INTRODUCTION
About These Machines
Foreword
"Most boys should learn a trade in order that they may become skilled workmen. The trained workman is always in demand...When a boy has learned a trade, becomes a skilled mechanic, he has excellent equipment with which to begin life's battle, but he need not stop there. George Westinghouse, the Wright Brothers, Henry Ford, and the Studebaker Brothers were mechanics, and it was their mechanical training that made their success possible." —Machine Shop
Equipment, 2nd Ed., 1920, by the O'Brien Brothers, founders of South Bend Lathe.
The first South Bend milling machine debuted in the 1950's. During that time, the milling machine and the already well-established South Bend lathes created the foundation of many tool rooms and school shops across America and beyond her borders. Many young men in those days came of age on South Bend equipment, becoming world-class machinists, mechanical engineers, inventors, and manufacturing visionaries.
A lot has changed in the world since then. Those same school shops have mostly been replaced by computer labs. The technology in the rotary dial phone, television set, mechanical calculator, computer, and camera of that decade could barely fit into one large room together—now they fit into a tiny box that is no bigger than a box of breath mints. And the average production machinist spends more time at a computer than at a machine. Technology has been much refined and the world operates on a much faster pace.
But some things haven't changed. The same human ingenuity and passion that created the best mechanical technology of today still exists within us. The core machines of the modern shop, like this South Bend milling machine, are still fundamentally important.
When you think about it, the greatest mechanical technology of the future will be what we create today. As the owner of a South Bend milling machine, you are now part of a great legacy. What will you create with yours?
Capabilities
These Milling Machines are built for daily, non-stop use in a busy industrial setting, tool room, or school shop. They are easy to set-up, truly accurate, and built to give you long years of service when properly cared for. These milling machines support workpieces up to 750 lbs. and are perfect for face milling, end milling, planing, slot or keyway cutting, dovetailing, routing, drilling, reaming, and boring to name a few. With the movable ram and tilting head, all these tasks can be performed on horizontal, vertical, and angled surfaces. When equipped with additional accessories, such as a rotary table or dividing head, these milling machines can do even more.
Features
These milling machines feature 3-axis table movement with built-in longitudinal power feed. They are constructed with high-grade Meehanite castings, and the saddle and knee ways are Turcite coated and built with wide dovetails for maximum support and accuracy through the full range of movement.
To ensure quality work results, we have equipped these mills with NSK or NTN spindle bearings that are rated to P4 (ABEC-
7) tolerances. The spindle tapers are R8 and the spindles have powered down feed with fine, medium, and coarse feed controls.
The headstocks are mounted on a wide-dovetail movable ram with 13" of travel on the column and 360° rotating capability. The headstocks themselves can swivel 90° left/right or 45° forward/back so they can be positioned for nearly any setup needed.
To reduce the time spent doing daily lubrication, we have outfitted these milling machines with a one-shot lubrication system that is as quick and easy as one pump of a lever.
And finally, each machine is designed to accept a circulating coolant system with room for the pump and reservoir in the column base. Additional features include a movable work light, and Allen Bradley electrical controls.

Cleaning & Protecting
For Machines Mfg. Since 8/09
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:

Lifting & Moving
PREPARATION
2. Place the lifting web straps under the ram
and connect them to the safety hook, as illustrated in Figure 6.
For Machines Mfg. Since 8/09
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.
The method of lifting and moving the mill described below requires at least two other people for assistance and a forklift with two lifting web straps rated for at least 3000 lbs. each.
Important: Before lifting the mill, make sure the four turret lock bolts (two on either side of the ram) are torqued to 47 ft/lbs.
To lift and move the mill:
1. Swing the ram around 180° from the position
that it was shipped in, then rotate the head upright, as illustrated in Figure 6 (refer to Ram Movement on Page 36 and Headstock Movement on Page 32 for detailed instructions).
Note: Place padding between the straps and the
mill to protect the ram and ways, and to keep from cutting the web straps.
3. Unbolt the mill from the shipping pallet.
4. With your assistants steadying the load to
keep it from swaying, lift the mill a couple of inches.
— If the mill tips to one side, lower to the
ground and adjust the ram or table to balance the load. Make sure to re-tighten the lock levers and bolts before lifting the mill again.
— If the mill lifts evenly, continue to move it
to its permanent location.
Note: After re-positioning the ram and
headstock, make sure they are locked in place to prevent unexpected movement during lifting and moving.

1. Make sure all tools, cables, and other items
are well clear of table movement as you follow these steps.
2. Refer to the Table Movement section,
beginning on Page 29, to understand how the power feed, table locks, and limit switch function.
3. Loosen the table locks on the front of the
table.
4. Plug the power feed power cord into a 110V
power outlet.
Note: There are 110V outlets on the right side of
the electrical cabinet that can be used for the power feed or other 110V accessories.
5. Make sure the power feed directional lever
is in the neutral (middle) position, turn the speed dial counterclockwise to the lowest setting, then flip the power switch to the on (up) position.
6. Turn the directional lever to the left, slowly
turn the speed dial clockwise to increase the speed, then confirm that the table is moving to the left.
7. Watch for the table limit stop to hit the
limit switch and turn the power feed OFF, stopping the table movement.

Operation Overview
For Machines Mfg. Since 8/09
The purpose of this overview is to give an example of a typical milling operation. Read through the steps below to better understand the controls and functions described later in this manual, so that you will know how they are used to successfully operate the mill.
This overview is not intended to be a step-by-step operational guide.
To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations.
In a typical milling operation, the operator does the following:
1. Examines the workpiece to make sure it is
suitable for milling.
2. Firmly clamps the workpiece to the table.
Loose hair, clothing, or jewelry could get caught in machinery and cause serious personal injury. 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.
5. Configures the mill for the correct spindle
speed of the operation.
6. Puts on personal protective gear and makes
sure the workpiece and table are clear of all tools, cords, and other items.
7. Starts the spindle rotation and performs the
operation.
3. Installs the correct cutting tool for the
operation.
4. Uses the manual downfeed and table
controls to confirm the correct positioning of the cutting tool and workpiece for the operation. If the X-axis power feed will be used during the operation, the operator confirms the speed and length of table movement required.
8. Turns the mill OFF.

OPERATION
Setting 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 mill controls to produce the required spindle speed.
Determining Spindle Speed
Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the cutting tool, as noted in Figure 31:
*Recommended
Cutting Speed (FPM) x 12
Tool Dia. (in inches) x 3.14
= SpindleSpeed (RPM)
Setting Spindle Speed Range
Setting the spindle speed range involves engaging and disengaging a spindle spline that uses gearing to increase or decrease the range of spindle speeds.
The procedures to set the speed range for the Model SB1024 and Model SB1025/SB1026 differ slightly. Use the appropriate section on the following pages for the mill when selecting the speed range.
To avoid damage to the spindle, gears, or cutting tools:
s 3PINDLEROTATIONMUSTBETURNED/&&AND
the spindle must be at a complete stop BEFORE you change the spindle speed range.
*Double if using carbide cutting tool
Figure 31. Spindle speed formula for milling.
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. These sources will help you take into account all applicable variables to determine the best spindle speed for the operation.

Spindle downfeed movement on the mill is controlled by three mechanisms: 1) The coarse downfeed handle, 2) the fine downfeed handwheel, and 3) the auto-downfeed system.
Using the Coarse Downfeed Handle
1. Make sure that the spindle rotation is
turned OFF and the spindle is at a complete stop.
2. To set the downfeed for manual control,
pull the downfeed selector knob out, then rotate it clockwise until the selector pin under the knob seats in the forward manual (disengaged) position, as shown in Figure 38 and illustrated in Figure 39 on the next page.
Note: It may be necessary to turn the spindle by
hand as you move the selector to enable the gears to mesh.

G. Downfeed Stop & Locking Wheel: Sets
the depth of spindle downfeed. The stop is threaded into position, then the locking wheel is use to secure it in place.
H. Quill Dog: Moves with the quill and spindle
and disengages the downfeed clutch lever when it engages either the top or the downfeed stop.
I. Downfeed Selector: Sets the mill for manual
downfeed or auto-downfeed control.
Using the Fine Downfeed Handwheel
1. Make sure that the spindle rotation is turned
OFF and the spindle is at a complete stop.
2. To set the downfeed for manual control, pull
the downfeed selector knob out, then rotate the selector clockwise until the selector pin seats in the forward manual (disengaged) position.
3. Set the auto-downfeed direction pin in the
neutral (middle) position to disengage the fine downfeed handwheel from the auto­downfeed gears.
When the spindle rotation is reversed, either by changing the spindle speed range or by using the spindle direction switch, the direction of spindle auto-downfeed will reverse.
C. Auto-Downfeed Direction Pin: Starts, stops,
and reverses the auto-downfeed direction.
D. Fine Downfeed Clutch Lever: Engages the
fine/auto-downfeed gears.
E. Downfeed Scale: Used with the quill dog,
shows the depth of spindle downfeed in inches.
F. Quill Lock Lever: Secures the quill in place
for increased stability during operations.
4. Position the downfeed stop for the spindle
depth that is correct for your operation, then secure it in place with the locking wheel.
5. Use the coarse downfeed lever to lower the
spindle slightly until you can pull the clutch lever out to the left and it locks in place. This will engage the handwheel with the quill and spindle.
6. To lower the spindle, rotate the fine
downfeed handwheel. When the quill dog meets the downfeed stop, the clutch lever will disengage and the spindle will return to the top.

OPERATION
For Machines Mfg. Since 8/09
Using the Auto-Downfeed System
When using the auto-downfeed system, the spindle will move in the direction you choose with the auto-downfeed direction pin. When the quill dog reaches the top or meets the downfeed stop, the downfeed clutch lever will release. Then, if the spindle was traveling upward, the movement will simply stop. If the spindle was traveling downward, then the spindle will move back to the top at a rate controlled by the return spring on the left side of the head.
To use the auto-downfeed system:
1. Make sure that the spindle rotation is turned
OFF and the spindle is at a complete stop.
2. To set the mill for auto-downfeed, pull the
downfeed selector knob out, then rotate the selector clockwise and seat the pin in the rear auto-downfeed (engaged) position, as illustrated in Figure 42.
Auto-Downfeed (Engaged) Position
4. Position the auto-downfeed direction pin for
the spindle travel that is correct for your operation. It may be necessary to rock the fine downfeed handwheel back-and-forth to move the pin all the way in or out.
Note: The direction pin has three positions: 1)
In for one downfeed direction, 2) middle for
neutral or no movement, and 3) out for the reverse direction. The direction of spindle travel for the in and out positions is relative to the direction of spindle rotation. Keep in mind that spindle rotation and downfeed direction will reverse when the spindle speed range is changed.
5. Make sure the clutch lever is all the way to
the right in the disengaged position so that the spindle will not travel when rotation is started.
Note: We recommend that you complete the
remaining steps without a cutting tool installed, without a workpiece in place, and the table lower than the maximum spindle downfeed travel. This will enable you to test and confirm the settings before beginning the actual cutting operation.
Figure 42. Downfeed selector in the auto-downfeed
(engaged) position.
3. Position the downfeed stop for the spindle
depth that is correct for your operation, then secure it in place with the locking wheel.
To avoid damage to the system gearing, never use the auto-downfeed system with spindle speeds over 1860 RPM.
6. Set the mill for the correct spindle speed,
then begin spindle rotation.

MAINTENANCE
Cleaning
Regular cleaning is one of the most important steps in taking good care of this lathe. Each operator is responsible for cleaning the machine immediately after using it or at the end of the day. We 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 ways and table 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 mill during cleaning. Remember, personal neatness gives you personality!
Unpainted & Machined Surfaces
Besides the ways and elevation leadscrew, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes 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.
Lubrication
The mill has numerous moving metal-to­metal contacts that require regular and proper lubrication to ensure efficient and long-lasting operation, and to protect your investment.
Other than the lubrication points covered in this section, all other bearings are internally lubricated and sealed at the factory. Simply leave them alone unless they need to be replaced.
Before performing any lubrication task, DISCONNECT THE MILL FROM POWER!
Important: Before adding lubricant, clean the debris and grime from the oil cup or grease fitting and the immediate area to prevent contamination of the oil cups, grease fittings, or new lubricant.
Use the schedule and information in Figure 48 as a daily guide for lubrication tasks. Follow the referenced sections on the following pages for detailed instructions.
The following recommended lubrication schedule is based on light to medium mill usage. Keeping in mind that lubrication helps to protect the value and operation of the mill, you may need to perform the lubrication tasks more frequently depending on your usage.

Hazards
As some coolant ages, it develops dangerous microbes which eventually proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by cleaning out the coolant reservoir on a monthly basis or sooner, if needed based on your daily inspection.
The important thing to keep in mind when working with coolant is to minimize exposure to your skin, eyes, and respiratory system by wearing the proper personal protective equipment, which includes splash-resistant safety glasses, long-sleeve gloves, protective clothing, and a NIOSH-approved respirator.
Drain
Plug

4. Place the catch pan under the drain plug,
then remove the plug and allow the fluid to drain into the pan.
5. Clean away debris and grime from the
coolant drain screens on the base of the mill.
6. Use rags, scrapers, and cleaning solvent
to thoroughly clean out the bottom of the reservoir.
Note: Use a cleaning solvent that is compatible
with the type of coolant. For instance, if you are using a water-base coolant, then use a water-base cleaning solvent.

Adjusting Gibs
Gibs are tapered lengths of metal that are sandwiched between two moving surfaces. Gibs control the gap between these surfaces and how they slide past one another. Correctly adjusting the gibs is critical to producing good milling results.
Tight gibs make table movement more accurate but stiff. Loose gibs make moving the table sloppy but easier to do. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind.
Gibs are adjusted with a screw on each end of the gib, that move the tapered gib back-and­forth to increase or decrease the friction pressure between the sliding surfaces. The process of properly adjusting the gibs requires trial-and­error and patience.

Make sure all table and knee locks are loose. Then, loosen one gib adjustment screw and tighten the other the same amount to move the gib. Use the ball handles/crank to move the table/ knee until you feel a slight drag in that path of movement.
Refer to Figures 61–63 to identify the locations of the table, saddle, and knee gibs, and one of the two adjustment screws for each.

Although the mill is equipped with double­bronzed longitudinal and cross leadscrew nuts to minimize backlash, leadscrews will always have a certain amount of backlash that will increase with normal wear.
Generally, 0.005"–0.010" leadscrew backlash is acceptable to ensure smooth movement and reduce the risk of premature thread wear. However, if you find it necessary to adjust leadscrew backlash, perform the procedures listed below.
