INTRODUCTION

About This Machine

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 people 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 Those same school shops have mostly been replaced by computer labs.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.

Capabilities

This Milling Machine is built for daily, non-stop use in a busy industrial setting, tool room, or school shop. It is easy to set-up, truly accurate, and built to give you long years of service when properly cared for. This milling machine supports workpieces up to 750 lbs. and is 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, this milling machine can do even more.

Features

This milling machine features 3-axis table movement with built-in longitudinal power feed. It is 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 this mill with NSK or NTN spindle bearings that are rated to P4 (ABEC-7) tolerances. The spindle taper is R8 and the spindle has powered down feed with fine, medium, and coarse feed controls.

The headstock is mounted on a wide-dovetail movable ram with 13" of travel on the column and 360° rotating capability. The headstock itself can swivel 90° left/right or 45° forward/back so it can be positioned for nearly any setup needed.

To reduce the time spent doing daily lubrication, we have outfitted this milling machine with a one-shot lubrication system that is as quick and easy as one pump of a lever.

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?

Quality Allen-Bradley electrical components and attention to detail provide dependable electrical control of the powered movements.

And finally, this milling machine comes with a circulating coolant system with the pump and reservoir in the column base.

2. Safety Accessories:

from the cutting operation can cause eye injury or blindness.

in addition to your safety glasses or use a face shield when milling.

3. Work Holding:

not properly clamped to the table could cause the workpiece to fly into the operator with deadly force! Before starting the machine, be certain the workpiece has been properly clamped to the table. NEVER hold the workpiece by hand during operation.

4. Spindle Speed:

breakage that could send flying debris at the operator and bystanders, use the correct spindle speed for the operation. Allow the mill to gain full speed before beginning the cut.

5. Spindle Direction Change:

rotation direction while it is spinning could lead to impact injury from broken tool or workpiece debris, and workpiece or machine damage. ALWAYS make sure the spindle is at a complete stop before changing spindle direction.

6. Stopping Spindle: To reduce the risk of hand

injuries or entanglement hazards, DO NOT attempt to stop the spindle with your hand or a tool. Allow the spindle to stop on its own or use the spindle brake.

7. Chip Cleanup:

sharp and hot and can cause burns or cuts. Using compressed air to clear chips could cause them to fly into your eyes, and may drive them deep into the working parts of the machine. Use a brush or vacuum to clear away chips and debris from the machine or workpiece and NEVER clear chips while the spindle is turning.

8. Machine Care & Maintenance:

the mill with excessively worn or damaged machine parts increases the risk of machine or workpiece breakage, which could eject hazardous debris at the operator. Operating a mill in poor condition will also reduce the quality of the results. To reduce this risk, maintain the mill in proper working condition by ALWAYS promptly performing routine inspections and maintenance.

9. Cutting Tool Usage:

sharp leading edges—handle them with care! Using cutting tools that are in good condition helps to ensure quality milling results and reduces the risk of personal injury from broken tool debris. Inspect cutting tools for sharpness, chips, or cracks before each use, and ALWAYS make sure the cutting tools are firmly held in place before starting the machine.

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.

Although 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:

• Disposablerags

• Cleaner/degreaser (certain citrus-based

degreasers work extremely well and they have non-toxic fumes)

• Safetyglasses&disposablegloves

Note: Automotive degreasers, mineral spirits, or

WD•40canbeusedtoremoverustpreventative.

Before using these products, though, test them on an inconspicuous area of a painted area to make sure they will not damage it.

Basic steps for removing rust preventative:

1. Put on safety glasses and disposable gloves.

2. Coat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

degreaser is effective, the rust preventative will wipe off easily.

Note: To clean off thick coats of rust preventative

on ﬂat surfaces, such as beds or tables, use

aPLASTICpaintscrapertoscrapeoffthe

majority of the coating before wiping it off

withyourrag.(Donotuseametalscraperor

it may scratch the surface.)

4. Repeat Steps 2–3 as necessary until clean,

then coat all unpainted surfaces with a quality metal protectant or light oil to prevent rust.

GAS

Gasoline and petroleum products have low flash points and can explode or cause fire if used for cleaning. Avoid using these products to remove rust preventative.

Many cleaning solvents are toxic if inhaled. Minimize your risk by only using these products in a well ventilated area.

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.

Weight Load

Refer to the Machine Speciﬁcations for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

Physical Environment

The physical environment where your machine is operated is important for safe operation and longevity of parts. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous or flammable chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature is outside the range of 41°– 104°F; the relative humidity is outside the range of 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device.

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated.

Lifting & Moving

PREPARATION

2. Place the lifting web straps under the ram

and connect them to the safety hook, as illustrated in Figure 5.

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 5 (refer to Ram Movement on Page 33 and Headstock Movement on Page 29 for detailed instructions).

Note: After re-positioning the ram and

headstock, make sure they are locked in place to prevent unexpected movement during lifting and moving.

Note: Place padding between the straps and the

mill to protect the ram and ways, and to keep from cutting the lifting straps.

Leveling machinery helps precision components, such as bed ways, 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.

To level a machine, place metal shims under the contact points where the machine rests on the ﬂoor. 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.

We strongly recommend securing your machine to the floor if it is hardwired to the power source. Consult with your electrician to ensure compliance with local codes.

Although not required, we recommend that you level your machine and mount it to the ﬂoor. Because this is an optional step and ﬂoor materials may vary, mounting hardware is not included. Generally, you can either bolt your machine to the ﬂoor or mount it on machine mounts.

PREPARATION

Spindle Break-In

Complete the spindle bearing break-in procedure to avoid rapid deterioration of spindle components when the mill is placed into operation.

The high-quality bearings and gears used in the mill are manufactured to very close tolerances. However, this does not guarantee perfect dimensional mating of the bearing components or exact meshing of gear teeth. Before operational stress is placed on these and other moving parts in the mill, complete this break-in procedure to conform these components to one another and ensure trouble-free performance from the mill.

To perform the spindle break-in procedure:

1. Successfully perform all the steps in the

Test Run section beginning on Page 21.

2. Make sure the spindle is at a complete stop.

3. Set the spindle speed to the low range (refer

to Setting Spindle Speed beginning on Page 34 for detailed instructions).

OPERATION

Operation Overview

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.

Tramming Spindle

After positioning the head at an angle and when your operation requires that the spindle axis be precisely perpendicular to the table, you must tram or align the spindle with the table to ensure the spindle is exactly 90° to the table.

This procedure involves mounting a dial test indicator to the quill or spindle, rotating it around the table, and adjusting the spindle axis (Z-axis) 90° to the table X- and Y-axes, as illustrated in Figure 27.

4. Re-tighten the lock bolts when you have the

head in the desired position.

Figure 27. Spindle axis perpendicular to the table X-

and Y-axes.

We encourage you to research the many variations of spindle tramming to find the one that works best for you. If you do not already have a preference for performing this operation, use the following widely-used procedure for accurately tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are not exactly parallel with the table top. You may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of that of the table.

Note: A precision-ground plate can be substituted for the parallel blocks. Keep in mind that the farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be.

To tram the spindle to the table:

1. DISCONNECT MILL FROM POWER!

2. Prepare the mill by performing the following

tasks:

• Tightenanytable,knee,quill,orram

locks that should be tight during the intended milling operation.

4. Install the indicator holder into the spindle or onto the quill, then mount the indicator onto it so that the point is as parallel to the block as possible (see the illustration in Figure 28 for an example).

Figure 28. Dial test indicator mounted.

5. To measure spindle alignment along the

X-axis, place the parallel block directly under the spindle and indicator across the length of the table, as illustrated in Figure 29.

Note: If you must re-position the quill or the

knee to accommodate the above step, then review the tasks in Step 2 to make sure the mill is properly prepared for the tramming operation.

Note: Generally, the goal in the next steps is to

get the difference of the indicator readings between the end of the parallel bar down to

0.0005". However, the acceptable variance will depend on the requirements for your operation.

6. Rotate the spindle by hand so that the

indicator point rests on one end of the parallel block, as illustrated in Figure 29, then zero the dial.

7. Rotate the spindle so that the indicator point

rests in the same manner on the other end of the block, then read the dial.

— If the indicator dial still reads zero or is

within the acceptable variance, continue on with Step 8.

— If the indicator dial has moved from zero

beyond the acceptable variance, you will need to compensate for that amount by rotating the head left or right. Repeat Steps 5–6 until you are satisfied with the spindle axis alignment along the table X-axis.

9. Place the parallel block directly under the spindle and across the width of the table, as illustrated in Figure 30.

Figure 30. Parallel block positioned for the Y-axis

10. Rotate the spindle so that the indicator point

rests on the parallel bar, as illustrated in Figure 30, then zero the dial.

11. Rotate the spindle so that the indicator point rests on the other end of the bar in the same manner, then read the dial.

8. Re-tighten the rotation lock bolts.

Note: It is a good idea to repeat Steps 5-6 again

Note: Keep one of the rotation lock bolts

snug so that the head does not move loosely while you adjust it small amounts.

in case the head moved slightly during the process of re-tightening the lock bolts.

— If the indicator dial still reads zero or

is within the acceptable variance, the spindle is precisely perpendicular to the table in both the X- and Y-axes and the tramming procedure is complete.

— If the indicator dial has moved from zero

beyond the acceptable variance, you will need to compensate for that amount by tilting the head forward or back. Repeat Steps 9–10 until you are satisfied with the spindle axis alignment along the table Y-axis.

Note: Keep one of the tilt lock bolts snug so

that the head does not move loosely while you adjust it small amounts.

12. Re-tighten the tilt lock bolts.

Note: It is a good idea to repeat Steps 9-10 again

in case the head moved slightly during the process of re-tightening the lock bolts.

Setting Spindle Speed

For Machines Mfg. Since 8 /09

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 33:

To avoid damage to the spindle, gears, or cutting tools:

• SpindlerotationmustbeturnedOFFand

the spindle must be at a complete stop BEFORE you change the spindle speed range.

• ThemillisdesignedtoONLYoperatewith

the spindle speed range selector in either the high or low position. To avoid damaging the moving parts inside the headstock, never start spindle rotation without the range selector detent pin firmly seated in either the high or low position.

• Whenchangingthespindlespeedrange

and the direction of spindle rotation reverses, you will need to either change the cutting tool for the direction of spindle rotation or use the spindle direction switch to compensate for the change.

Figure 33. 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.

Setting Spindle Speed Range

Setting the spindle speed range involves using a lever to engage/disengage the spindle spline with the bull gear.

To set the spindle speed range:

1. DISCONNECT MILL FROM POWER!

2. Use the chart below to find the spindle speed

range that includes the required spindle speed for your operation.

Spindle Speed Ranges

Low Range 60–575 RPM

High Range 575–5000 RPM

When the spindle speed range is changed, the direction of spindle rotation will reverse. ALWAYS know which way the spindle is rotating before beginning the cutting operation.

-34-

Page 37

3. Press the spindle speed range lever shown

in Figure 34 toward the head to release the detent pin from the detent plate, move selector so that the pin is over the other detent, then release the selector.

— When the lever is pointing to the rear and

the front detent is engaged, the low speed range is selected. Conversely, when the lever is pointing toward the front and the rear detent is engaged, the high speed range is selected.

OPERATION

Downfeed Controls

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

OPERATION

Fine Downfeed Controls

There are a number of devices on the head that are used with the fine downfeed handwheel or the auto-downfeed system. Refer to Figure 39 and the descriptions below to become familiar with these controls.

Figure 39. Fine downfeed controls.

A. Auto-Downfeed Rate Selector: Selects one of

the three auto-downfeed rates.

B. Fine Downfeed Handwheel: Manually

controls fine spindle downfeed.

G. Downfeed Stop & Locking Wheel: Sets

the depth of spindle downfeed. The stop is threaded into position, then the locking wheel is used to secure it in place.

H. Quill Dog: Moves with the quill and spindle

and disengages the downfeed clutch lever when it meets either the top or 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 slightly lower the spindle until you can pull the clutch lever out to the left and it locks in place. This will engage the fine 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 releases. Then, if the spindle was traveling upward, the movement simply stops. If the spindle was traveling downward, then the spindle moves 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 40.

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 40. 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 3000 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 machine. 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 45 as a daily guide for lubrication tasks.

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.

Running the coolant pump without adequate coolant in the reservoir may permanently damage the coolant pump. This action is considered abusive and is not covered by the warranty.

3. If the level of coolant in the reservoir is less

than 2", add more fluid through the screen to fill the tank.

The coolant reservoir on this mill is only designed to store coolant. During storage some fluids grow dangerous microbes, which will produce an unpleasant odor. As well, due to the collection of toxic metal chips in the fluid, the fluid can become a potent and extremely poisonous solution to humans and animals. Use the correct personal protection equipment and immediately change the coolant if either of these conditions occur.

Follow Federal, State, and the coolant manufacturer's requirement to safely dispose of the used coolant.

MAINTENANCE

5. Remove the two pump mounting cap screws

and move the pump out of the way (see Figure 57).

Figure 57. Location of coolant pump.

6. Use rags, scrapers, and cleaning solvent

to thoroughly clean out the bottom of the reservoir and the base of the pump. Make sure that the interior is completely dry before adding new coolant.

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.

Machine Storage

To avoid rust problems or corrosion damage, use the following information to protect your investment when storing the mill for any length of time.

• DISCONNECTMILLFROMPOWER!

• Lubricatethemillasdirectedinthe

Lubrication section beginning on Page 43.

• Cleanoutthecoolantreservoirinthebase

surfaces, then coat them with a light weight grease or rust preventative. Take care to ensure these surfaces are completely covered but that the grease or rust preventative is kept off painted surfaces.

Note: If the machine will be out of service for

only a short period of time, use way oil or a good grade of medium-weight machine oil (not auto engine oil) in place of the grease or rust preventative.

Adjusting Gibs

Gibs are tapered lengths of metal between two dovetail sliding 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.

DISCONNECT MILL FROM POWER BEFORE ADJUSTING THE GIBS!

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 handwheel/crank to move table/ knee until you feel a slight drag in that path of movement.

Refer to Figures 58–60 on the next page to identify the locations of the table, saddle, and knee gibs, and one of the two adjustment screws for each.

Note: It will be necessary to remove small parts, such as way wipers and covers, to access the gib adjustment screws.

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.

underneath the left side of the table.

Saddle Gib &

Adjustment Screw

Figure 59. Saddle gib and adjustment screw.

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.
