About This Machine
Foreword
Capabilities
"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.
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.
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.
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.
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same school shops have mostly been replaced
by computer labs.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.
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.
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.
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.
Quality Allen-Bradley electrical components and
attention to detail provide dependable electrical
control of the powered movements.
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?
And finally, this milling machine comes with a
circulating coolant system with the pump and
reservoir in the column base.

startup. Always disconnect power
contain chemicals known to cause cancer,
respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.
BEFORE any service or adjustments,
including changing blades or other tooling.
16. Difficult Operations: Attempting
difficult operations with which you are
unfamiliar increases the risk of injury.
If you experience difficulties performing
the intended operation, STOP! Seek an
alternative method to accomplish the
same task, ask a qualified expert how the
operation should be performed, or contact
our Technical Support for assistance.
10. Secure Workpiece/Tooling: Loose
workpieces, cutting tools, or rotating
spindles can become dangerous projectiles
if not secured or if they hit another object

Additional Milling Machine Safety
1. Understanding Controls: The mill is a
complex machine that presents severe
cutting or amputation hazards if used
incorrectly. Make sure you understand the
use and operation of all controls before you
begin milling.
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: Chips from the operation are
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.
2. Safety Accessories: Flying chips or debris
from the cutting operation can cause eye
injury or blindness. Always use a chip guard
in addition to your safety glasses or use a
face shield when milling.
3. Work Holding: Milling a workpiece that is
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.
8. Machine Care & Maintenance: Operating
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.
4. Spindle Speed: To avoid tool or workpiece
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.
9. Cutting Tool Usage: Cutting tools have very
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.
5. Spindle Direction Change: Changing spindle
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.

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.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
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.
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.
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.
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.
Before cleaning, gather the following:
•
•
Disposable rags
Cleaner/degreaser (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
3. Wipe off the surfaces. If your cleaner or
degreaser is effective, the rust preventative
will wipe off easily.
•
Safety glasses & disposable gloves
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.)
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.
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.
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.

Bolting to Concrete Floors
Leveling & Mounting
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.
Anchor
Bolt
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.

and Anchor
Leveling
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.
Figure 7. Common types of fasteners for bolting
machinery to concrete floors.
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.

Rotating Head
Tramming Spindle
1. DISCONNECT MILL FROM POWER!
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.
2. Loosen the four rotation lock bolts on the
face of the head shown in Figure 26.
!
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.

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.

Setting Spindle Speed
Using the correct spindle speed is important
for safe and satisfactory results, as well as
maximizing tool life.
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.
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.
•
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.
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:
•
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.
*Recommended
Cutting Speed (FPM) x 12
= SpindleSpeed (RPM)
Tool Dia. (in inches) x 3.14
*Double if using carbide cutting tool
Figure 33. Spindle speed formula for milling.
Setting Spindle Speed Range
Setting the spindle speed range involves using a
lever to engage/disengage the spindle spline with
the bull gear.
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.
To set the spindle speed range:
1. DISCONNECT MILL FROM POWER!
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.
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
High Range
60–575 RPM
575–5000 RPM
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.
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.

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.
— 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.

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.
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.
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.
To use the auto-downfeed system:
1. Make sure that the spindle rotation is turned
OFF and the spindle is at a complete stop.
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.
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.
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.
Auto-Downfeed (Engaged) Position
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,

Cleaning
Lubrication
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.
The mill has numerous moving metal-to-
metal 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

gives you personality!
Use the schedule and information in Figure 45
as a daily guide for lubrication tasks.
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.
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.

check the level of the coolant.
BIOLOGICAL & POISON
HAZARD!
Use the correct personal
protection equipment
when handling cutting
fluid. Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
A small amount of coolant is lost during normal
operation. Check the coolant reservoir regularly
and fill it if necessary. We recommend changing
the coolant every three months or sooner if it
develops an unpleasant odor.

5. Remove the two pump mounting cap screws
and move the pump out of the way (see
Figure 57).
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.
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.
Follow Federal, State, and the coolant
manufacturer's requirement to safely dispose
of the used 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
Adjusting Gibs
To avoid rust problems or corrosion damage,
use the following information to protect your
investment when storing the mill for any length
of time.
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.
•
•
DISCONNECT MILL FROM POWER!
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.
Lubricate the mill as directed in the
Lubrication section beginning on Page 43.
•
•
Clean out the coolant reservoir in the base
of the mill as directed in the Changing
Coolant section on Page 49.
Gibs are adjusted with a screw on each end of
the gib, that move the tapered gib back-and-
forth to increase or decrease the friction pressure
between the sliding surfaces. The process of
properly adjusting the gibs requires trial-and-
Thoroughly clean all unpainted, bare metal
surfaces, then coat them with a light weight
grease or rust preventative. Take care to
ensure these surfaces are completely covered error and patience.
but that the grease or rust preventative is
kept off painted surfaces.
DISCONNECT MILL FROM POWER BEFORE
ADJUSTING THE GIBS!
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.
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.
•
Loosen the belts to prevent them from
stretching during storage. Post a reminder
on the mill that the belts need to be re-
installed or tensioned before resuming
operations.
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.
•
•
Place a few moisture absorbing desiccant
packs inside the electrical and control panel
boxes.
Note: It will be necessary to remove small parts,
such as way wipers and covers, to access the gib
adjustment screws.
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 plastic parts.
•
At least once a month, start the mill 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.

Adjusting Leadscrew
Backlash
Leadscrew backlash is the amount the leadscrew
rotates before the attached device begins to
move.
Table Gib &
Adjustment Screw
Although the mill is equipped with double-
bronzed longitudinal and cross leadscrew nuts to
minimize backlash, leadscrews will always have
a certain amount of backlash that will increase
with normal wear.
Figure 58. Table gib and adjustment screw
underneath the left side of the table.
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.
