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same school shops have mostly been replaced
by computer labs.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

PREPARATION
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:
s $ISPOSABLErags
s #LEANERDEGREASER (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
s 3AFETYGLASSESDISPOSABLEGLOVES
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:

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.
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.

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.

PREPARATION
Leveling & Mounting
Generally, you can either bolt your machine
to the floor or mount it on machine mounts.
lthough not required, we recommend that you
secure the machine to the floor and level it while
doing so. Because this is an optional step and
floor materials may vary, hardware for securing
the machine to the floor is not included.
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.
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.

The mill comes with a power feed unit for X-axis
table travel. Proper operation of the limit switch
attached to the front middle of the table is
critical for the safe use of this power feed unit.
If the power feed does not operate as expected
during the following steps, disconnect it from
power and contact our Tech Support at (360) 7341540 for assistance.
To test the X-axis power feed unit and table
limit switch:
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.
8. Turn the directional lever through the
neutral (middle) position and all the way to
the right. The table should begin moving to
the right.
9. Confirm that the table stops moving when
the limit stop presses against the limit
switch plunger.
10. Move the directional lever to the neutral
(middle) position and flip the power switch to
the off (down) position.

PREPARATION
Spindle Break-In
Since the mill head was rotated parallel to
the table for shipping purposes, you will need
Complete the spindle bearing break-in
procedure to avoid rapid deterioration of
spindle components when the mill is placed
into operation.
to tram the spindle with the table if your first
cut requires a 90° alignment. Refer to the
Tramming Spindle section on Page 33 for
detailed instructions.
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 25.
2. Make sure the spindle is at a complete stop.
3. Set the spindle speed to the low range
(refer to Setting Spindle Speed Range
beginning on Page 37 for detailed
instructions).
4. Start the spindle rotation at a medium speed
and let the mill run for 20 minutes.

OPERATION
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.
