INTRODUCTION
INTRODUCTION
About These Machines
Foreword
"The screw cutting engine lathe is the oldest and most important of machine tools and from it all other machine tools have been developed. It was the lathe that made possible the building of the steamboat, the locomotive, the electric motor, the automobile and all kinds of machinery used in industry. Without the lathe our great industrial progress of the last century would have been impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathes represented in this manual are a modern day version of the screw cutting lathes that trace their roots back to the 1700's, which were themselves technological improvements of the bow lathe that can be traced back thousands of years to the ancient Egyptians.
Now, almost 300 years later, these modern "screw cutting" lathes are not just a piece of refined machinery, but a culmination of human ingenuity and knowledge embodied into the design and synergy of thousands of interworking parts—some of which represent the life's work and dreams of many inventors, mechanical engineers, and world-class machinists—including the likes of Leonardo da Vinci, Henry Maudsley, and the founders of South Bend Lathe, John and Miles O'Brien.
And now the torch is passed to you—to take the oldest and most important type of machine tool—and carry on the tradition. As the operator of a South Bend Lathe, you now join the ranks of some very famous and important customers, such as Henry Ford, who used the machines he purchased to help him change the world.
Capabilities
These EVS Toolroom Lathes are built for daily use in a busy industrial setting. Loaded with many nice features and high-precision parts, these lathes excel at making fine tools, dies, thread gauges, jigs, and precision test gauges— however, they are by no means delicate. Thick castings, heavy weight, and quality construction throughout provide the necessary brawn for demanding production and manufacturing tasks.
Features
As the name implies, these lathes feature EVS (Electronic Variable Speed) spindle control, which allows the operator to quickly set the exact spindle speed within the available range of 20–2500 RPM. Spindle speed is displayed on a digital readout and controlled within each speed range with the use of a dial—no changing gears or looking up complex lever positions on a chart.
The beds of these lathes are constructed with Meehanite castings that have been precision hardened and ground in the traditional 3-V prismatic design—long used on South Bend Lathes for its accuracy, durability, and rigidity.
The headstock features quick-change gear levers and an adjustable clutch mechanism for the feed rod that can be set to prevent damage in the event of a crash.
To further ensure a high degree of accuracy, these lathes are equipped with NSK or NTN spindle bearings. The spindles are the D1-6 camlock type with an MT#6 taper and 2.0625" bore. The tailstock quills have an MT#4 taper and offer 6" of travel.
The EVS lathes also include a pressurized headstock oiling system that pre-lubricates bearings/gears before the spindle starts and delivers perfect lubrication during low speed operations (compare to conventional splash and bath oil systems that leave bearings/gears starved for oil when the spindle is first started and during low speed operations).
Finally, these EVS toolroom lathes are packed with standard features, such as a complete coolant system, easy-to-clean chip drawer, one­shot way lubrication system, included steady and follow rests, adjustable work lamp, foot brake, and powered cross feed.

SAFETY
SAFETY
Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending on how it is installed and maintained, and the operator's experience, common sense, risk awareness, working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This responsibility includes proper installation in a safe environment, personnel training and usage authorization, regular inspection and maintenance, manual availability and comprehension, application of safety devices, integrity of cutting tools or accessories, and the usage of approved personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property damage from negligence, improper training, machine modifications, or misuse. Failure to read, understand, and follow the manual and safety labels may result in serious personal injury, including amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are defined as follows:
Death or catastrophic harm WILL occur.
Death or catastrophic harm COULD occur.
Basic Machine Safety
1. Owner’s Manual: All machinery and
machining equipment presents serious injury hazards to untrained users. To reduce the risk of injury, anyone who uses THIS item MUST read and understand this entire manual before starting.
2. Personal Protective Equipment:
or servicing this item may expose the user to flying debris, dust, smoke, dangerous chemicals, or loud noises.

Attempting
For Machines Mfg. Since 7/09 EVS Toolroom Lathes
SAFETY
Additional Metal Lathe Safety
1. Clearing Chips. Metal chips can easily cut
bare skin—even through a piece of cloth. Avoid clearing chips by hand or with a rag. Use a brush or vacuum to clear metal chips.
2. Chuck Key Safety. A chuck key left in the
chuck can become a deadly projectile when the spindle is started. Always remove the chuck key after using it. Develop a habit of not taking your hand off of a chuck key unless it is away from the machine.
3. Tool Selection. Cutting with an incorrect
or dull tool increases the risk of accidental injury because extra force is required for the operation, which increases risk of breaking or dislodging components, which can cause small shards of metal to become dangerous projectiles. Always select the right cutter for the job and make sure it is sharp. A correct, sharp tool decreases strain and provides a better finish.
4. Securing Workpiece. An improperly secured
workpiece can fly off of the lathe spindle with deadly force, which can result in a severe impact injury. Make sure the workpiece is properly secured in the chuck or faceplate before starting the lathe.
5. Large Chucks. Large chucks are very heavy
and difficult to grasp, which can lead to crushed fingers or hands if mishandled. Get assistance when installing or removing large chucks to reduce this risk. Protect your hands and the precision-ground ways by using a chuck cradle or piece of plywood over the ways of the lathe when servicing chucks.
6. Safe Clearances. Workpieces that crash into
other components on the lathe may throw dangerous projectiles in all directions, lead­ing to impact injury and damaged equipment. Before starting the spindle, make sure the workpiece has adequate clearance by hand­rotating it through its entire range of motion. Also, check the tool and tool post clearance, chuck clearance, and saddle clearance.
7. Speed Rates. Operating the lathe at the
wrong speed can cause nearby parts to break or the workpiece to come loose, which will result in dangerous projectiles that could cause severe impact injury. Large workpieces must be turned at slow speeds. Always use the appropriate feed and speed rates.
8. Stopping Spindle by Hand. Stopping the spin-
dle by putting your hand on the workpiece or chuck creates an extreme risk of entangle­ment, impact, crushing, friction, or cutting hazards. Never attempt to slow or stop the lathe spindle with your hand. Allow the spindle to come to a stop on its own or use the brake (if equipped).
9. Crashes. Driving the cutting tool or other
lathe components into the chuck may cause an explosion of metal fragments, which can result in severe impact injuries and major damage to the lathe. Reduce this risk by releasing automatic feeds after use, not leav­ing lathe unattended, and checking clear­ances before starting the lathe. Make sure no part of the tool, tool holder, compound slide, cross slide, or carriage will contact the chuck during operation.
10. Long Stock Safety. Long stock can whip vio-
lently if not properly supported, causing seri­ous impact injury and damage to the lathe. Reduce this risk by supporting any stock that extends from the chuck/headstock more than three times its own diameter. Always turn long stock at slow speeds.
11. Coolant Safety. Contaminated cutting fluid
is a very poisonous biohazard that can cause personal injury from skin contact alone. Incorrectly positioned cutting fluid nozzles can splash on the operator or the floor, resulting in an exposure or slipping hazard. To decrease your risk, change cutting fluid regularly and position the cutting fluid nozzle where it will not splash or end up on the floor.

Cleaning & Protecting
For Machines Mfg. Since 7/09
The unpainted surfaces are coated at the factory with a heavy-duty rust preventative that prevents corrosion during shipment and storage. The benefit of this rust preventative is that it works very well. The downside is that it can be time-consuming to thoroughly remove.
Be patient and do a careful job when cleaning and removing the rust preventative. The time you spend doing this will reward you with smooth-sliding parts and a better appreciation for the proper care of the unpainted surfaces.
lthough there are many ways to successfully remove the rust preventative, we have cleaned thousands of machines and found the following process to be the best balance between efficiency and minimized exposure to toxic fumes or chemicals.
Before cleaning, gather the following:

Avoid chlorine-based solvents, such as acetone or brake parts cleaner that may damage painted surfaces. Always follow the manufacturer’s instructions when using any type of cleaning product.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. #OATALLSURFACESTHATHAVERUSTPREVENTATIVE
with a liberal amount of your cleaner or degreaser and let them soak for a few minutes.
3. Wipe off the surfaces. If your cleaner or

Lifting & Moving
This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help and use power equipment.
Do not attempt to lift or move this lathe if you do not have the proper equipment or the necessary assistance from other people. All lifting equipment must be rated to at least 5,000 lbs. to account for dynamic loads from bouncing or pulling that may be applied while lifting. Refer to the Things You'll Need section on Page 8 for details.
To lift and move your lathe:
1. Prepare the permanent location for the
lathe.

7. Unbolt the lathe from the shipping pallet,
then with an assistant to help keep the lathe from swaying, raise the lathe a couple of inches.
— If the load is not well balanced, or you
see any other difficulties with the lifting equipment, immediately lower the lathe to the pallet again. Resolve any lifting or balancing issues, then repeat this step.
For accurate turning results and to prevent warping the cast iron bed and ways, the lathe bedways MUST be leveled from side-to-side and from front-to-back.
Re-check the bedways 24 hours after installation, two weeks after that, and then annually to make sure they remain level.
Leveling machinery helps precision components, such as bedways, remain straight and flat during the lifespan of the machine. Components on an unleveled machine may slowly twist due to the dynamic loads placed on the machine during operation.
For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.
See the figure below for an example of a high precision level.
8. With assistance to steady the load, move it to
the prepared location and lower it in place.
Figure 10. Example of a precision level.

Refer to the Lubrication
Section in this Manual
for Recommended
Oil Type.
The headstock, gearbox, and apron oil reservoirs must have the proper amount of oil in them before the lathe can be operated for the first time.
Running the lathe without oil in a gearbox is considered unwarrantable abuse, which may result in damage to the bearings and gears. Refer to the Lubrication section, beginning on Page 56, for details on how to check and add oil.
-14-
For Machines Mfg. Since 7/09 EVS Toolroom Lathes
In addition to the gearboxes, we also recommend that you lubricate all other points on the machine at this time. This can be accomplished by following the maintenance schedule on Page
54.
Note: If your lathe was shipped with oil in the gearboxes, do not change that oil until after the break-in period.
PREPARATION
This machine is equipped with a frequency drive that contains sensitive electronics, which can be damaged by a phase converter. DO NOT use a phase converter to power this machine. Doing so will void the warranty.

Power Connection
Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.
Once all preparation steps previously described in this manual have been completed, the machine can be connected to the power source. In order to be connected to the power source, a circuit must be installed/prepared that meets the requirements of the lathe, and a power connection method must be established for that circuit. The following lists show the minimum requirements for each model, and instructions follow for each connection method.
Note About Power Cords: Using an incorrectly sized cord causes electrical components on the machine and the cord to become very hot, which will greatly decrease the life of electrical components or result in fire. For best results, use the shortest length of cord possible for your machine, and never use a smaller cord gauge than the specified minimum.

4. Make sure the cord/wires have loose slack
between the strain relief and terminal connections, then tighten the strain relief to secure the power cord.
Note: The strain relief must be tightened against
the outermost jacket of the cord. Avoid over­tightening the strain relief or it may crush the cord and cause a short.
5. Test the strain relief to ensure it is properly
tightened by pulling the cord from outside the box with light-to-moderate force. When the strain relief is properly tightened, the cord will not slide.
Figure 14. Location to connect power inside main
electrical cabinet.
2. Thread the power cord through the strain
relief, and up to the main power switch shown in Figure 14.
3. Connect the incoming L1, L2, L3 and ground
wires to the main power switch terminals, as illustrated in Figure 15.
6. Close and lock the main electrical box door.
Hardwiring Lathe to Power Source
Hardwire setups require power supply lines to be enclosed inside of conduit, which is securely mounted and constructed in adherence to applicable electrical codes.
A hardwire setup for this machine must be equipped with a locking disconnect switch as a means to disconnect the power during adjustments or maintenance, which is a typical requirement for lock-out/tag-out safety programs (commonly required by OSHA).
Figure 16 shows a simple diagram of a hardwire setup with a locking disconnect switch between the power source and the machine.

Correcting Out-of-Phase Wiring
This sub-section is only provided for troubleshooting. If you discover during the test run that the lathe will not operate, or that the spindle runs backwards, the lathe may be wired out of phase. Without the proper test equipment to determine the phase of power source legs, wiring machinery to 3-phase power may require trial-and-error. Correcting this is simply a matter of reversing the positions where two of the incoming power source wires are connected.
To correct wiring that is out of phase:
1. Push the stop button, turn the main power
switch to OFF, and disconnect the machine from power (or shut OFF and lock out the power source if hardwired).
2. Open the electrical box and disconnect the
L1 and L2 wires shown in Figure 15 on the "To Power Source" side of the switch.
3. Connect the L1 wire to the terminal where
the L2 wire was connected originally.
4. Connect the L2 wire to the terminal where
the L1 wire was connected originally.
5. Close and latch the electrical box, and
reconnect the machine to the power source.
Test Run
After all preparation steps have been completed, the machine and its safety features must be tested to ensure correct operation. If you discover a problem with the operation of the machine or its safety components, shut the machine down, disconnect it from power, and do not operate it again until you have resolved the problem.
Note: The variable speed on this machine is controlled by a frequency drive unit constructed with sensitive electronics. These electronics can be damaged if power is disconnected during operation. Therefore, unless the stop button and brake lose functionality, always properly shut the machine down before disconnecting it from the power source.
A Troubleshooting section is provided, starting on Page 74, to assist you with solutions if a problem occurs or if the lathe does not function as described in this section.
If you need additional help after reviewing the troubleshooting section, or you are not confident troubleshooting the machine on your own, contact our tech support at (360) 734-1540.
To test run your machine:
1. Read and follow the safety instructions at
the beginning of the manual, take required safety precautions, and make sure all previous preparation steps discussed in this manual have been followed and completed.
2. Clear away all tools and objects used during
assembly, lubrication, and preparation.
3. DISCONNECT LATHE FROM POWER!
4. Make sure that the chuck and jaws, if
installed, are secure (refer to Chuck and Faceplate Mounting on Page 27).
Note: If a chuck is not installed on the lathe, you
do not need to install one for this test.

OPERATION
OPERATION
Operation Overview
The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used durin operation, so they can more easily understand the controls discussed later in this manual.
Note: Due to the generic nature of this overview, it is not intended to be an instructional guide for performing actual machine operations. To learn more about specific operations and machining techniques, seek training from people experienced with this type of machine, and do additional research outside of this manual by reading "how-to" books, trade magazines, or websites.
To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations.
To complete a typical operation, the operator does the following:
1. Puts on safety glasses, rolls up sleeves,
removes jewelry, and secures any clothing, jewelry, or hair that could get entangled in moving parts.
2. Examines the workpiece to make sure it
is suitable for turning, then mounts the workpiece in one of the chucks or on the faceplate, and removes the chuck key from the chuck.
3. Mounts the tooling, aligns it with the
workpiece, then backs it away to establish a safe startup clearance.
4. Clears all tools from the lathe.
5. Sets the correct spindle speed range for the
operation, and turns the spindle speed dial all the way counterclockwise (to the lowest speed) to avoid the possibility of damage from a high speed start.
6. Checks for safe clearances by rotating
the workpiece by hand at least one full revolution.
Loose hair, clothing, or jewelry could get caught in machinery and cause serious injury or death. Keep these items away from moving parts at all times to reduce this risk.
During operation, small metal chips may become airborne, leading to serious eye injury. Wear safety glasses to reduce this risk.
7. Moves slides to where they will be used
during operation.
8. If using power feed, selects the proper feed
rate for the operation.
9. Turns the main power switch ON, resets
the stop button so it pops out, then moves the spindle ON/OFF lever down to start spindle rotation. The spindle will rotate counterclockwise (down and toward the operator when facing the front of the lathe).
10. Turns the spindle speed dial clockwise to the
desired RPM.
11. Uses the carriage handwheels or power
feed options to move the tooling into the workpiece for operations.
12. When finished cutting, moves the ON/OFF
lever to the center position to turn the lathe OFF, then removes the workpiece.

Chuck & Faceplate Mounting
This lathe is shipped with the 3-jaw chuck installed. This is a scroll-type chuck, meaning that all three jaws move in unison when adjusted.
The included 4-jaw chuck features independent jaws, which are used for square or unevenly­shaped stock, and to mount work that needs to be adjusted to near "0" total indicated runout.
If neither chuck can hold your workpiece, the cast-iron faceplate has slots for T-bolts that hold standard or custom clamping hardware. With the correct clamping hardware, this faceplate will hold non-cylindrical parts.

Mounting Chuck or Faceplate
The 4-jaw chuck is shipped with six camlock studs that must be installed before the chuck can be mounted, as explained in this procedure. If you have not yet installed the camlock studs, complete the instructions in "Installing and Adjusting Camlock Studs" on Page 29.
To mount a chuck or faceplate:
1. DISCONNECT LATHE FROM POWER!
2. Lay a chuck cradle (see Figure 39) or
plywood under the chuck or faceplate and over the bedway to protect the precision ground surfaces from damage and reduce injury if fingers get pinched.
3. Clean away debris and oily substances from
the mating surfaces of the spindle and chuck or faceplate.
4. Inspect and make sure that all camlock
studs are undamaged, are clean and lightly oiled, and that the camlock stud cap screws are in place and snug.
Never install a chuck or faceplate without having the camlock cap screws in place or fully tightened. If you ignore this notice, the chuck may not be removable since the camlock studs may turn with the camlocks and never release.
5. Position the chuck/faceplate in front of the
spindle nose, align the chuck timing marks, as shown in Figure 42, and align the cam­lock studs with the sockets, then carefully insert the chuck or faceplate onto the spindle.
6. Tighten camlocks in a star pattern to draw
the chuck up evenly on all sides while reducing chance of alignment, and make sure to tighten camlocks in an incremental manner to ensure that no camlock gets fully tightened all at once (i.e., snug the camlocks on the first pass, then moderately tighten on the next pass, then fully tighten on the third pass).
As you tighten the camlocks, the chuck or
faceplate will snug up onto the spindle nose. When fully tightened, the cam line will fall between the two "V" marks on the spindle nose, as shown in Figure 43.
Cam Line

Refer to Chuck & Faceplate Mounting instructions on Page 27 to mount the faceplate to the spindle.
The 12" faceplate included with your lathe offers a wide range of uses, including machining non­concentric workpieces, straight turning between centers, off-center turning, and boring.
The tools needed for mounting a workpiece will vary depending on the type of setup you have.
Failure to properly secure a workpiece to the faceplate could cause the workpiece to be thrown from the lathe with deadly force at the operator or bystanders. Use a minimum of three independent clamping devices to hold a non-concentric workpiece onto the faceplate.

the sleeve into the spindle bore through the chuck or faceplate.
Figure 66 shows an example of the dead
center installed in the spindle, using a lathe dog and faceplate for turning between centers.
Dead Center
Dead Centers
The dead center achieves more accurate results than a live center, but it requires low spindle speeds and a small amount of oil to reduce friction heat that may damage the workpiece.
Use the dead center in the spindle, because the workpiece does not rotate on the tip and does not generate friction.
Use the carbide-tipped dead center in the tailstock where the workpiece will rotate against it and generate friction. The carbide-tipped dead center can better withstand the effects of friction; however, the tip of the center must be lubricated to avoid premature wear and maximize smooth operation. Also, using low spindle speeds will reduce the heat and wear from friction.
Live Centers
A live center has bearings that allow the center tip and the workpiece to rotate together, and can be installed in the spindle and the tailstock quill for higher speeds.
Figure 66. Example of using a dead center with a
faceplate and lathe dog.
To avoid premature wear of the dead center or damage to the workpiece, use low spindle speeds and keep the tip of the dead center mounted in the tailstock well lubricated.

Removing Center from Spindle
To remove the sleeve and center from the spindle, insert a piece of round bar stock or similar tool through the outboard end (on the left side of the headstock), then tap the sleeve loose.
Note: Hold onto the sleeve and center as you tap them loose to avoid dropping them and damaging the tip of the center or the bedways.
Mounting Center in Tailstock
Either a dead center or live center can be mounted in the tailstock. Mounting instructions are the same for both. Figure 67 shows an example of a dead center mounted in a tailstock.
Dead Center
To mount a center in the tailstock:
1. DISCONNECT LATHE FROM POWER!
2. Thoroughly clean and dry the tapered
mating surfaces of the tailstock quill bore and the carbide-tipped dead center, making sure that no lint or oil remains on the tapers.
3. Use the tailstock quill handwheel to feed the
quill out from the casting about 1". (Do not feed the quill out of the casting more than 2" or stability and accuracy will be reduced.)
4. Insert the center into the tailstock quill.
5. Seat the center firmly into the quill during
workpiece installation by rotating the quill handwheel clockwise to apply pressure, with the center engaged in the center hole in the workpiece.
Note: Only apply enough pressure with the
tailstock quill to securely mount the workpiece between centers. Avoid over­tightening the center against the workpiece, or it may become difficult to remove later, and it will result in excessive friction and heat, which may damage the workpiece and the center.
Figure 67. Example of using a dead center installed in
the tailstock.
Removing Center from Tailstock
To remove the center from the quill, hold onto it with a rag in one hand, then rotate the tailstock handwheel counterclockwise to draw the quill back into the casting until the center releases.

Steady Rest
The steady rest supports long shafts and can be mounted anywhere along the length of the bed.
To install and use the steady rest:
1. DISCONNECT LATHE FROM POWER!
2. Thoroughly clean the machined base of
the steady rest, then place it on the lathe bedways so the triangular notch fits over the bedway prism.
OPERATION
5. Close the steady rest so that the workpiece
is inside the finger rollers, then tighten the lock knob.
6. Loosen the three wing bolts so the finger
roller positions can be adjusted.
7. Use the finger adjustment knobs to
just touch the finger rollers against the workpiece without causing workpiece deflection.
8. Tighten the three wing bolts.
3. Position the steady rest where required to
properly support the workpiece, then tighten the hex nut shown in Figure 68 to secure it in place.

Compound Slide
The compound slide handwheel has an indirect­read graduated scale. This means that the distance shown on the scale represents the actual distance the tool moves, which will remove twice as much material from the diameter of the workpiece. The base of the compound slide has another graduated scale used for setting the tool to a specific angle.
To set the compound slide at a certain angle:
1. Loosen the two hex nuts at the base of the
compound slide (1 of 2 shown in Figure 71).
Compound

Four-Way Tool Post
The four-way tool post is mounted on top of the compound slide and allows a maximum of four tools to be loaded simultaneously.
The four-way tool post allows for quick indexing to different tools, which is accomplished by loosening the top handle, rotating the tool post to the desired position, then re-tightening the handle to lock the tool into position.
Tool Needed Qty
Tool Post T-Wrench ...............................................1
To load the tool post:
1. Choose the desired cutting tool.
2. Loosen the tool post bolts so that the cutting
tool can fit underneath them.
Note: If necessary, place one steel shim
underneath the cutting tool so the cutting tip is properly aligned with the workpiece. The shim should be as long and as wide as the cutting tool to properly support it.
Figure 71. Compound slide set at an angle.
2. Rotate the compound to the desired angle,
as indicated by the scale at the base, then retighten the two hex nuts.
Tip: The first time you set the angle of the
compound rest for cutting threads, mark the location on the cross slide as a quick reference point. This will allow you to quickly return the compound rest to that exact angle the next time you need to cut threads.
Over-extending a cutting tool from the tool post will increase the risk of it breaking during operation, which may cause metal pieces to be thrown at the operator or bystanders with great force. Only extend a cutting tool 2.5 times the width of its cross-section or less (i.e., 2.5 x 0.5" = 1.25").
3. Firmly secure the cutting tool with at least
two tool post bolts (Figure 72).

The adjustable apron stop system is designed to stop the longitudinal carriage movement at optional locations when the feedrod is engaged.
When the leadscrew is engaged for threading operations, the adjustable apron stop system will not disengage the leadscrew—you must move the half nut lever instead. Otherwise, the carriage can crash into the chuck, or if it contacts the stop, the leadscrew shear pin will break.
Before doing any threading operations, make sure to loosen the stop collar so it slides freely on the feedrod.

Spindle Speed
Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.
To set the spindle speed for your operation, you will need to: (1) Determine the best spindle speed for the cutting task, and (2) configure the lathe controls to produce the required spindle speed.
Determining Spindle Speed
Many variables affect the optimum spindle speed to use for any given operations, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown in Figure 78:
*Recommended
Cutting Speed (FPM) x 12
Dia. of Cut (in inches) x 3.14
*Double if using carbide cutting tool
Figure 78. Spindle speed formula for lathes.
= SpindleSpeed (RPM)
Cross Slide Handwheel
The cross slide handwheel moves the tool toward and away from the work. Turning the dial clockwise moves the slide toward the workpiece. Adjust the graduated scale by holding the handwheel with one hand and turning the dial with the other. The graduated scale reads in
0.001" increments and is a "direct-read" which means that the distace on the collar reflects the amount removed from the diamter of the workpiece.
Compound Slide Handwheel
The compound slide handwheel controls the position of the cutting tool relative to the workpiece. The compound is adjustable for any angle within its range. Angle adjustment is secured by two nuts on the base of the compound. The graduated scale reads in 0.001" increments and is a "indirect-read" which means that the distace on the collar reflects the distance that the tool moves.
Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.
A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life.
The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.
Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. All of these sources will help you take into account all the applicable variables in order to determine the best spindle speed for the operation.

OPERATION
Setting Spindle Speed
1. Make sure the spindle is turned OFF and it
has come to a complete stop.
2. Use the chart in Figure 79 to determine the
available spindle speed range closest to your calculated spindle speed.
For Machines Mfg. Since 7/09
Make sure the variable speed dial is turned all the way to the left (counterclockwise) before turning the lathe ON, or it may start up at a dangerously high rate of speed.

Low 20-400
High 400-2500
Figure 79. Spindle speed range chart.
If the headstock is in high range (400-2500 RPM), and if the spindle speed dial is turned completely to the left, the tachometer may show a speed lower than the 400 RPM listed on the headstock label. This headstock label indicates the allowable spindle speed for cutting operations within that range. If the lever is in high range, do not attempt cutting operations below 400 RPM.
3. Adjust the spindle speed range lever to the
range that covers your calculated spindle speed.
Note: To shift the spindle speed range lever, you
may need to apply pressure to the lever and slightly rotate the spindle by hand.

4. Turn the spindle ON and slowly turn the
variable speed dial to carefully adjust the spindle speed (shown on the digital display) to your calculated spindle speed.
Power Feed
On this machine, both the carriage and cross slide have power feed capability. The rate that these components move (feed rate) is controlled by how the levers are configured on the gearbox.
Feed rate and spindle speed must be considered together. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed rate to use with that spindle speed.
Often, the experienced machinist will use the feeds and speeds given in their reference charts or web calculators as a starting point, then make minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.
The carriage can alternately be driven by the leadscrew for threading operations. However, this section covers using the power feed option for the carriage and cross slide components for non-threading operations. To learn how to power the carriage for threading operations, refer to the Threading Controls section Page 48.

End Gear Setup
The gearbox drive gear on this lathe can be configured for the "normal position" or the "alternate position" (both described in following paragraphs), depending upon the type of operation to be performed. The lathe is shipped with the end gears in the normal position. Gears must be thoroughly cleaned and re-coated in grease before installing (refer to Page 61), and the backlash must be maintained at 0.005" for correct meshing.
Normal Position
The 24T end gear is installed in the top position, the 44T/56T end gears in the middle position, and the 57T end gear in the bottom position, as shown in Figure 86. In the normal position, the 56T and 57T gears are meshed, which allows for inch and metric threading and all general feed operations.

Cleaning
Regular cleaning is one of the most important steps in taking care of this lathe. We recommend that each operator be responsible for cleaning the machine immediately after using it or at the end of the day. We also recommend that the cleaning routine be planned into the workflow schedule, so that adequate time is set aside to do the job right.
Typically, the easiest way to clean swarf from the bed ways and chip drawer is to use a wet/dry shop vacuum that is dedicated for this purpose only. The small chips leftover after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as it may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands.
All visible swarf should be removed from the lathe during cleaning.

Monitoring Oil Temperature
During operations, regularly monitor the oil temperature shown in the sight glass in Figure
109. The temperature of the headstock oil must remain under 170° F. or the oil will start to overheat and break down, causing it to lose its lubrication properties.
The headstock lubrication system is the most important lubrication system on the machine. It consists of an electric oil pump, a low oil pressure kill switch, a holding tank, oil lines, and a distribution manifold. The headstock has a series of oil lines that direct oil to key locations, such as the spindle bearings and headstock gearing, to ensure that they always remain well lubricated.
The oil pump automatically turns ON and begins oiling the headstock components when the main power switch is turned ON and the emergency stop button is reset. The oil is pumped before the spindle is started to protect the spindle bearings against potential damage from dry starts.
Checking & Adding Oil
The sight glass on the side of the headstock oil tank, shown in Figure 109, shows the oil level and temperature; the bottom line represents the minimum oil level and the top line represents the maximum oil level. The lathe must be powered down and stopped when to get an accurate reading on the oil level.
Oil Fill Spout
Under normal conditions, the oil should not reach 170° F.; however, if it does, shut down the machine and allow the oil to cool. Investigate why the oil is getting so hot. Possibilities may be poor ventilation, excessive work loads, poor oil quality, oil is breaking down (losing lubricity) due to long term use, or extreme work site temperatures.
If possible, correct the conditions causing the oil to get hot. If the oil is old or you suspect it is of poor quality, change it. If the work loads or working environment are extreme, reduce the duty cycle of the lathe to allow the oil to cool down when it gets hot.
If the oil temperature ever exceeds 170° F., change it as soon as possible to make sure the spindle bearings have high quality lubrication.
Verifying Oil Pump Operation
To prevent costly damage to the headstock gears and bearings, a kill switch will shut the lathe down if the oil pump stops working or the oil level is too low. You can verify that the pump is working by looking at the sight glass shown in Figure 109. When working correctly, oil can be seen flowing across the sight glass.

Cleaning Pump System & Changing Oil
The headstock oil pump system must be cleaned and the oil changed after the break-in period and then annually (or every six months with hard service or extreme working conditions).
To clean the oil pump system:
1. DISCONNECT LATHE FROM POWER!
2. Remove the cap from the fill spout shown in
Figure 110.

3. Place at least a 3-gallon drain pan under the
tank and remove the drain plug to empty the oil into the pan.
4. Clean away any dust, debris, metal shavings,
or grime from the access cover.
5. Using a 4mm hex wrench, remove the four
access cover cap screws, then use the cap screw in the center as a handle and lift off the access cover.
6. Put on splash-proof safety glasses, rubber
gloves, and a respirator rated for fumes.
7. Using mineral spirits and rags, wipe down
the inside of the tank to clean it. Make sure to soak up any excess mineral spirits with a dry rag, so it does not stay in the tank.
10. Re-install the suction screen.
Tip: Consider placing one or two magnets at the
bottom of the tank to collect any fine metal particles generated by the headstock drive train. This will make cleaning easier the next time around and ensure that more metal particles are kept out of the headstock oil.
11. Re-install the drain plug.
12. Refill the tank with oil (refer to Page 56 for
the recommended type and amount of oil to use).
13. Replace the fill spout plug.

Ways & Slides
The way pump shown in Figure 117 lubricates the saddle and cross slide way guides with the oil from the apron reservoir.
To use the way pump to lubricate the ways, pull the pump knob out for two or three seconds and then push it in. The pump draws oil from the apron reservoir and then forces it through drilled passages to the way guides.
Repeat this process and move the carriage left/ right and the cross slide forward/backward to distribute oil along the way guides.
Lubricate the guides once before and once after operating the lathe. If the lathe is in a moist or dirty environment, increase the lubrication interval and make sure to keep the oil level full.

Unpainted & Machined Surfaces
Besides the ways and leadscrew, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes the top of the saddle, the cross slide, compound slide, tool post, chuck, feedrod, and any other surface you can find that could be vulnerable to rust if left unprotected (this especially includes any parts that may be exposed to water soluble cutting fluids). Typically with these parts, a thin film of oil is all that is necessary for protection. Any quality metal protectant can be used to protect machined surfaces, including either of the oils you use elsewhere in the lathe.

Oil Amount ..........................................1 or 2 Drops
Lubrication Frequency ................................... Daily
This lathe has five ball oiler locations (see Figures 118–119) that should be oiled on a daily basis. In order to properly squirt oil into the ball oiler mechanisms, you will need an oil can or gun.
Cleaning Electrical Box Filter
The door of the electrical box contains an air filter (Figure 120) to prevent dust from entering the box as the cooling fan pulls in cool air to reduce heat.
The air filter should be cleaned on a monthly basis to ensure proper air circulation in the electrical box. A clogged air filter will not allow the cooling fan to do its job, which could result in a decreased lifespan of the electrical components.
Cooling Fan

MAINTENANCE
End Gearing
Grease Type ............................................... NLGI#2
Frequency ................Annually or When Swapping
The end gears, shown in Figure 121, should always have a thin coat of heavy grease to minimize corrosion, noise, and wear. Care must be taken to avoid over-greasing because excess grease may be flung onto the V-belts, which will reduce optimal power transmission from the motor.
End
Gears
Figure 121. Location of end gears that require grease.
Handling & Care
Make sure to clean and lubricate any gears you install or swap. Unless you are very careful during handling and storage, the coating of grease on the gears will easily pickup dirt or debris, which can then spread to the other gears and increase the rate of wear.
Make sure the cover remains installed whenever possible to keep the gears free of dust or debris from the outside environment.
Lubricating
1. DISCONNECT LATHE FROM POWER!
2. Remove the headstock side cover and all the
end gears shown in Figure 121.
3. Clean the end gears thoroughly with mineral
spirits to remove all the old grease. Use a small brush if necessary to clean between the teeth.
4. Clean the shafts from which the end gears
were removed, and wipe up any old grease splatters in the vicinity and on the inside of the headstock cover.
5. With clean hands, apply a thin layer of
grease on the gears. Make sure to get grease between the gear teeth, but not so much that it fills the voids between the teeth.
6. Install the end gears and mesh them
together with an approximate backlash of
0.005". Once the gears are meshed together, apply a small dab of grease in the crux of where the gears mesh together—this grease will spread around when the gears start moving and re-coat any areas scraped off during installation.
Annual Maintenance
Once a year, remove all the end gears, clean them thoroughly, and apply a new coating of grease. Even if the headstock side cover has been kept in place throughout the year, it is still possible for dust from the V-belts to build-up in the grease, and the grease may also start to break down with extended or heavy use.

Cutting Fluid System
The cutting fluid system consists of a fluid tank, pump, and flexible nozzle. The pump pulls fluid from the tank and sends it to the valve, which controls the flow of cutting fluid to the work area. When the valve is opened or closed, the fluid comes out of the nozzle and drains through the chip drawer and into the catch tray and then into the tank where it is picked up again by the pump. Figure 122 shows many of these components and their locations.

Hazards
As some cutting fluid ages, dangerous microbes can proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by replacing the old cutting fluid on a monthly basis, as indicated in the maintenance schedule.
The important thing to keep in mind when working with the cutting fluid is to minimize exposure to your skin, eyes, and respiratory system by wearing the proper PPE (personal protective equipment), such as splash-resistant safety glasses, long-sleeve gloves, protective clothing, and a NIOSH approved respirator.
BIOLOGICAL & POISON
HAZARD! Use the correct personal protection equipment when handling cutting fluid. Follow federal, state, and fluid manufacturer requirements for proper disposal.

Although most swarf from machining operations falls into the chip tray and stays there, some small chips drain into the tank. The pump uses a screen to prevent it from picking up the small swarf that ends up in the tank.
Since the swarf is spread throughout the coolant system, cleaning the system on a regular basis is a requirement to maintain the life of the pump.

2. Place the 5-gallon bucket behind the lathe
and underneath the coolant nozzle. If you have the optional hose, place the hose in the bucket. Otherwise, you may need to hold the bucket up to the coolant nozzle to prevent coolant from splashing outside of the bucket.
3. Turn the cutting fluid pump ON (or have
another person turn it ON if you are holding the bucket), and pump the old cutting fluid out of the tank. Turn the pump OFF immediately after fluid stops flowing.
Running the pump without adequate fluid in the tank may permanently damage it. This is abuse and not covered by the warranty.
4. DISCONNECT LATHE FROM POWER!
5. Remove the vented cover shown in Figure
122 and slide the tank half way out of the base, as shown in Figure 123.
8. Slide the tank partially into the base and
reconnect fluid hose (if removed).
Tip: Leave one or more magnets at the bottom
of the tank to collect metal chips and make cleanup easier next time.
9. Refill the tank with new cutting fluid, then
slide the tank completely into the base.
10. CONNECT LATHE TO POWER.
11. Open the valve on the cutting fluid nozzle.
12. Turn the cutting fluid pump ON to verify
that fluid cycles properly, then turn it OFF.
Note: It may take a few seconds for the pump to
start circulating fluid; however, if fluid does not start coming out within the first minute, turn the pump OFF so you do not burn out the pump motor. Try priming the pump manually by pour cutting fluid down into the nozzle, then repeat Step 13.
— If necessary, disconnect fluid hose from
pump, where shown in Figure 124.

MAINTENANCE
Machine Storage
If the machine is not properly prepared for storage, it may develop rust or corrosion. If decommissioning this machine, use the steps in this section to ensure that it remains in good condition for later use.
To prepare your machine for short-term storage (up to a year):
1. Pump out the old cutting fluid, and flush the
lines and tank with warm, soapy water.
2. DISCONNECT LATHE FROM POWER!
3. Thoroughly clean all unpainted, bare metal
surfaces, then apply a liberal coat of way oil.
4. Lubricate the machine as outlined in the
lubrication section.
5. Cover and place the machine in a dry area
that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy.
6. Once or twice a month, depending on the
ambient humidity levels in the storage environment, wipe down the machine as outlined in Step 3.
For Machines Mfg. Since 7/09
To prepare your machine for long-term storage (a year or more):
1. Run the lathe for 10 minutes to bring the
gearboxes to operating temperature, then drain and refill the all gearboxes with fresh oil.
Note: During extended storage (more than two
years), any component above the oil level may rust from condensation. We recommend overfilling any sealed gearbox. However, over time there will be some seepage around some shafts and seals. If any gearbox is overfilled make sure to put a tag on the controls as a reminder for the maintenance person to correct the oil level before starting the machine. If a gearbox cannot be overfilled, every few months manually rotate the shaft or spindle to coat any exposed gears with oil.
2. Pump out the old cutting fluid, and flush the
lines and tank with warm, soapy water.
3. DISCONNECT LATHE FROM POWER!
4. Thoroughly clean all unpainted, bare metal
surfaces, then apply a liberal coat of way oil, a heavy grease, or rust preventative. Take care to ensure these surfaces are completely covered but that the rust preventative or grease is kept off of painted surfaces.
7. Every few months, start the machine
and run all gear-driven components for a few minutes. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion, especially during the winter months.
-64-
5. Lubricate the machine as outlined in the
lubrication section.
6. Loosen or remove machine belts so they do
not become stretched during the storage period. (Be sure to also affix a maintenance note near the power button as a reminder that the belts have been loosened or removed.)
7. Place a few moisture absorbing desiccant
packs inside of the electrical box.
8. Cover and place the machine in a dry area
that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy.

Backlash Adjustment
SERVICE
Cross Slide Leadscrew
Tools Needed: Qty
Backlash is the amount of free play felt while switching rotation directions with the handwheel. This can be adjusted on the compound and cross slide leadscrews.
Reducing backlash to less than 0.001" is impractical. Avoid the temptation to overtighten the backlash set screw while adjusting. Overtightening leads to accelerated wear of the wedge, nut, and leadscrew.
Compound Leadscrew
Hex Wrench 3mm .................................................1
Hex Wrench 5mm ................................................1
Backlash is adjusted by loosening all four cap screws shown in Figure 126, and then tightening the center set screw, which pushes down on a wedge and forces the nut apart, taking up lash in the nut and leadscrew.
If you end up adjusting the nut too tight, loosen the set screw, tap the cross slide a few times with a rubber or wooden mallet, and turn the handle slowly back-and-forth, until the handle turns freely.
Tools Needed: Qty
Hex Wrench 3mm .................................................1
Backlash is adjusted by tightening the set screws shown in Figure 125. When these screws are adjusted against the leadscrew nut, they offset part of the nut to remove play between the nut and leadscrew.
If you end up adjusting the nut too tight, loosen the set screws, tap the compound a few times with a rubber or wooden mallet, and turn the handle slowly back and forth until it moves freely.
To readjust the backlash, rock the handle back and forth, and tighten the screws slowly until the backlash is at approximately 0.001" as indicated on the handwheel dial.
To re-adjust the backlash, rock the handle back and forth and tighten the set screw slowly until the backlash is at approximately 0.001" as indicated on the handwheel dial.

Gib Adjustment
The goal of adjusting the cross slide, tailstock, saddle, and compound gib screws is to remove sloppiness in the ways without over-adjusting them to the point where the slides become stiff and difficult to move.
In general, loose gibs cause poor finishes and tool chatter; however, over-tightened gibs cause premature wear on the slide, leadscrew, and nut, and are difficult to operate.
The gibs are tapered and held in position by a screw at each end. To adjust the gib, turn one screw a
1
4 turn counterclockwise, so both screws move toward the same direction. Now test the feel of the sliding component by turning the handwheel, and adjust the gib screws as necessary to make it tighter or looser.
The gib adjustment process usually requires some trial-and-error. Repeat the adjustment process as necessary until you find the best balance between loose and stiff movement. Most machinists find that the ideal gib adjustment is one where a small amount of drag or resistance is present yet the handwheels are still easy to move.
Figures 128–131 show the location of the screws for each gib on this machine.

Hundreds of Thousands of Lathes Sold With a Tradition of Quality Since 1906!
© November, 2009 by South Bend Lathe Co. For Machines Mfg. Since 7/09
Scope of Manual
This manual assumes that the reader has a basic understanding of safe electrical practices and general wiring concepts, including how to safely make wire connections and avoid shorts. This manual is intended to be a reference source in the event that a repair or component replacement becomes necessary during the life of the machine. If an electrical repair becomes necessary, and you do not have experience working with electricity or performing wiring tasks, we strongly encourage you to get help from an experienced individual, such as an electrician, or from our technical support. Following this advice will help you avoid serious personal injury, maintain your warranty, and keep your machine operating correctly.

Electrical Safety Instructions
These pages are accurate at the time of printing. In the constant effort to improve, however, we may make changes to the electrical systems of future machines. Study this section carefully. If you see differences between your machine and what is shown in this section, call Technical Support at (360) 734-1540 for assistance BEFORE making any changes to the wiring on your machine.
Shock Hazard: Working on wiring that is
1. connected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!
Wire Connections: All connections must be
2.
tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.
Modifications: Using aftermarket parts or
3.
modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
Motor Wiring: The motor wiring shown
4.
in these diagrams is current at the time of printing, but it may not match your machine. Always use the wiring diagram inside the motor junction box.
Circuit Requirements: You MUST follow
5.
the requirements at the beginning of this manual when connecting your machine to a power source.
Capacitors/Inverters: Some capacitors and
6.
power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.
Wire/Component Damage: Damaged wires
7.
or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components before completing the task.
Experiencing Difficulties: If you are
