South Bend Vertical Spindle Precision Milling Machine
(circa 1958)
For Machines Mfg. Since 8 /09Model SB1027
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same school shops have mostly been replaced
by computer labs.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.

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:
•Disposablerags
•Cleaner/degreaser (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
•Safetyglasses&disposablegloves
Note: Automotive degreasers, mineral spirits, or
WD•40canbeusedtoremoverustpreventative.
Before using these products, though, test them
on an inconspicuous area of a painted area to
make sure they will not damage it.
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
aPLASTICpaintscrapertoscrapeoffthe
majority of the coating before wiping it off
withyourrag.(Donotuseametalscraperor
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.

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

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.

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 it 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.

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.

Model SB1027
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).
For Machines Mfg. Since 8 /09
Since the mill head was rotated parallel to
the table for shipping purposes, you will need
to tram the spindle with the table if your first
cut requires a 90° alignment. Refer to the
Tramming Spindle section on Page 30 for
detailed instructions.
Inspections &
Adjustments
The following list of adjustments were performed
at the factory before the machine was shipped:
Be aware that machine components can shift
during the shipping process. Pay careful
attention to these adjustments during operation
of the machine. If you find that the adjustments
are not set according to the procedures in this
manual or your personal preferences, re-adjust
them.
4. Start the spindle rotation at a medium speed
and let the mill run for 20 minutes.
5. Stop the spindle rotation and allow the
spindle to come to a complete stop by itself.
6. Set the spindle speed to the high range, then
start the spindle rotation at a medium speed
and let the mill run for another 20 minutes.
7. Stop the spindle rotation, and turn the mill
OFF.
The spindle break-in of the mill is now complete!
