INTRODUCTION
About This Machine
Foreword
"The screw cutting engine lathe is the oldest and
most important of machine tools and from it all
other machine tools have been developed. It was
the lathe that made possible the building of the
steamboat, the locomotive, the electric motor, the
automobile and all kinds of machinery used in
industry. Without the lathe our great industrial
progress of the last century would have been
impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathe represented in this manual is a
modern day version of the screw cutting lathes
that trace their roots back to the 1700's, which
were themselves technological improvements of
the bow lathe that can be traced back thousands
of years to the ancient Egyptians.
Now, almost 300 years later, these modern
"screw cutting" lathes are not just a piece of
refined machinery, but a culmination of human
ingenuity and knowledge embodied into the
design and synergy of thousands of interworking
parts—some of which represent the life's work
and dreams of many inventors, mechanical
engineers, and world-class machinists—including
the likes of Leonardo da Vinci, Henry Maudsley,
and the founders of South Bend Lathe, John and
Miles O'Brien.
And now the torch is passed to you—to take
the oldest and most important type of machine
tool—and carry on the tradition. As the operator
of a South Bend Lathe, you now join the ranks
of some very famous and important customers,
such as Henry Ford, who used the machines he
purchased to help him change the world.
Features
This 16-Speed Gearhead Lathe is packed with
standard features and equipment, such as a
complete coolant system, easy-to-clean chip
drawer, one-shot way lubrication system,
included steady and follow rests, chuck guard,
adjustable work lamp, foot brake, powered cross
feed, 3- and 4-jaw chucks, and faceplate. Models
SB1054F and SB1055F also feature a Fagor
2-axis 20iT DRO.
Spindle speeds are controlled by a 2-speed motor
and convenient headstock levers, which allow the
operator to quickly set the spindle speed within
the available range of 40–2000 RPM.
Bed ways are constructed with Meehanite
castings that are precision hardened and ground
in the traditional 3-V prismatic design—long
used on South Bend Lathes for accuracy,
durability, and rigidity.
Headstock features quick-change gear controls
and an adjustable clutch mechanism that can
be set to disable the feed rod to prevent crash
damage. Spindle is a D1-6 (camlock type) with an
MT#6 taper and 2
MT#4 taper and offers 6" of travel.
Finally, to ensure long-lasting accuracy in the
most demanding shops, the spindle is equipped
with Japanese NTN bearings.

Capabilities
This 16-Speed Toolroom Lathe is built for daily
use in a busy industrial setting. Loaded with
many nice features and high-precision parts, this
lathe excels at making fine tools, dies, thread
gauges, jigs, and precision test gauges—however,
it is by no means delicate. Thick castings, heavy
weight, and quality construction throughout
provide the necessary brawn for demanding
production and manufacturing tasks.

Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including

Attempting difficult
For Machines Mfg. Since 3/11 16-Speed Gearhead Lathe
SAFETY
Additional Metal Lathe Safety
Clearing Chips. Metal chips can easily cut bare
skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag.Use a
brush or vacuum to clear metal chips.
Chuck Key Safety. A chuck key left in the chuck
can become a deadly projectile when the
spindle is started. Always remove the chuck
key after using it. Develop a habit of not
taking your hand off of a chuck key unless it
is away from the machine.
Tool Selection. Cutting with an incorrect or
dull tool increases the risk of accidental
injury due to the extra force required for the
operation, which increases risk of breaking
or dislodging components that can cause
small shards of metal to become dangerous
projectiles. Always select the right cutter for
the job and make sure it is sharp. A correct,
sharp tool decreases strain and provides a
better finish.
Securing Workpiece. An improperly secured
workpiece can fly off the lathe spindle with
deadly force, which can result in a severe
impact injury. Make sure the workpiece is
properly secured in the chuck or faceplate
before starting the lathe.
Speed Rates. Operating the lathe at the wrong
speed can cause nearby parts to break or the
workpiece to come loose, which will result in
dangerous projectiles that could cause severe
impact injuries. Large or non-concentric
workpieces must be turned at slow speeds.
Always use the appropriate feed and speed
rates.
Stopping Spindle by Hand. Stopping the spindle
by putting your hand on the workpiece
or chuck creates an extreme risk of
entanglement, impact, crushing, friction, or
cutting hazards. Never attempt to slow or
stop the lathe spindle with your hand. Allow
the spindle to come to a stop on its own or
use the brake.
Crashes. Aggressively driving the cutting tool
or other lathe components into the chuck
may cause an explosion of metal fragments,
which can result in severe impact injuries
and major damage to the lathe. Reduce this
risk by releasing automatic feeds after use,
not leaving lathe unattended, and checking
clearances before starting the lathe.
Make sure no part of the tool, tool holder,
compound rest, cross slide, or carriage will
contact the chuck during operation.
Chucks. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or
hands if mishandled. Get assistance when
handling chucks to reduce this risk. Protect
your hands and the precision-ground ways
by using a chuck cradle or piece of plywood
over the ways of the lathe when servicing
chucks.
Safe Clearances. Workpieces that crash into
other components on the lathe may throw
dangerous projectiles in all directions,
leading to impact injury and damaged
equipment. Before starting the spindle,
make sure the workpiece has adequate
clearance by hand-rotating it through its
entire range of motion. Also, check the tool
and tool post clearance, chuck clearance, and
saddle clearance.
Long Stock Safety. Long stock can whip violently
if not properly supported, causing serious
impact injury and damage to the lathe.
Reduce this risk by supporting any stock
that extends from the chuck/headstock more
than three times its own diameter. Always
turn long stock at slow speeds.
Coolant Safety. Coolant is a very poisonous
biohazard that can cause personal injury
from skin contact alone. Incorrectly
positioned coolant nozzles can splash on
the operator or the floor, resulting in an
exposure or slipping hazard. To decrease
your risk, change coolant regularly and
position the nozzle where it will not splash
or end up on the floor.

Chuck Safety
SAFETY
For Machines Mfg. Since 3/11
Entanglement. Entanglement with a rotating
chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt
to slow or stop the lathe chuck by hand,
and always roll up long sleeves, tie back
long hair, and remove any jewelry or loose
apparel BEFORE operating.
Using Correct Equipment. Many workpieces can
only be safely turned in a lathe if additional
support equipment, such as a tailstock or
steady rest, is used. If the operation is too
hazardous to be completed with the lathe or
existing equipment, the operator must have
enough experience to know when to use a
different machine or find a safer way.
Disconnect Power. Serious entanglement or
impact injuries could occur if the lathe is
started while you are adjusting, servicing, or
installing the chuck. Always disconnect the
lathe from power before performing these
procedures.
Proper Maintenance.
maintained and lubricated to achieve
maximum clamping force and withstand
the rigors of centrifugal force. To reduce
the risk of a thrown workpiece, follow all
maintenance intervals and instructions in
this document.
All chucks must be properly
Chuck Capacity. Avoid exceeding the capacity
of the chuck by clamping an oversized
workpiece. If the workpiece is too large to
safely clamp with the chuck, use a faceplate
or a larger chuck if possible. Otherwise, the
workpiece could be thrown from the lathe
during operation, resulting in serious impact
injury or death.
Clamping Force. Inadequate clamping force
can lead to the workpiece being thrown
from the chuck and striking the operator
or bystanders. Maximum clamping force
is achieved when the chuck is properly
maintained and lubricated, all jaws are
fully engaged with the workpiece, and the
maximum chuck clamping diameter is not
exceeded.
Trained Operators Only. Using a chuck
incorrectly can result in workpieces coming
loose at high speeds and striking the
operator or bystanders with deadly force.
To reduce the risk of this hazard, read
and understand this document and seek
additional training from an experienced
chuck user before using this chuck.

Circuit Rating....................................... 15 Amps
Connection .. Hardwire with Locking Switch
Full-Load Current Rating
The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.
SB1053 Full-Load Rating ................ 20.3 Amps
SB1054F Full-Load Rating ............ 10.15 Amps
SB1055F Full-Load Rating ............ 10.23 Amps
The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.
If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.
power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit must
be safely sized to handle the full-load current
that may be drawn from the machine for an
extended period of time.
For your own safety and protection of property,
consult a qualified electrician if you are unsure
about wiring practices or electrical codes in
your area.
Note: The circuit requirements listed in this
manual apply to a dedicated circuit—where only
one machine will be running at a time. If this

PREPARATION
Grounding Requirements
In the event of certain types of malfunctions or
breakdowns, grounding provides a path of least
resistance for electric current—in order to reduce
the risk of electric shock.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding
wire. If repair or replacement of the power cord
is necessary, do not connect the equipmentgrounding wire to a live (current carrying)
terminal.
Check with a qualified electrician or service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the machine is properly grounded.
If you ever notice that a cord is damaged or
worn, disconnect it from power, and immediately
replace it with a new one.
440V Operation
As specified in the Circuit Requirements
section for the Models SB1054F and SB1055F
on the previous page, these machines must be
hardwired to the power source, using a locking
switch (see Figure 12). These machines must
also be connected to a grounded metal permanent
wiring system; or to a system with an equipmentgrounding conductor. Due to the complexity and
high voltage involved, this type of installation
MUST be done by a qualified electrician or
service personnel.
Electrocution or fire may
occur if machine is not
correctly grounded and
attached to the power
supply. Use a qualified
electrician to ensure a safe
power connection.
220V Operation
The power cord and plug specified under Circuit
Requirements section for the Model SB1053 on

PREPARATION
Cleaning & Protecting
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:
1. Put on safety glasses and disposable gloves.
2. #OATALLSURFACESTHATHAVERUSTPREVENTATIVE
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.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
Note: Automotive degreasers, mineral spirits, or

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.
Remove the end gear cover and end gears,
and use a stiff brush with mineral spirits
to clean the rust preventative from the
gears and shafts. DO NOT get any cleaner
or rust preventative on the V-belts, as it
could damage them or make them slip
during operations. If the belts do become

7. Unbolt the lathe from the shipping pallet,
then with two other people to help keep
the lathe from swaying, raise it a couple of
inches.
— If the load is not well balanced, or you
see any other difficulties with the lifting
equipment, immediately lower the lathe
to the pallet again. Resolve any lifting or
balancing issues, then repeat this step.
For accurate turning results and to prevent
warping the cast iron bed and ways, the lathe
bedways MUST be leveled from side-to-side
and from front-to-back on both ends.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.
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.

PREPARATION
To level the machine, use a precision level to
make sure the bedways are level from side-toside and from front-to-back.
Assembly
With the exception of the handwheel handles, the
lathe is shipped fully assembled.
— If using the included leveling pads (see
Figure 22), place them under the six
leveling jack bolt locations, then adjust
the bolts to level the lathe.
To install the handwheel handles, thread the
large handle into the carriage handwheel and the
small handle into the cross slide handwheel, as
shown in Figure 24.

— If using mounting hardware that does not
allow for adjustment, level the lathe by
placing metal shims between the lathe
base and the floor before bolting it down.
Bolting to Concrete Floors
Lag screws and anchors, or anchor studs
(below), are two popular methods for bolting
machinery to a concrete floor. We suggest you
research the many options and methods for
mounting your machine and choose the best one
for your specific application.

Most electrical codes require that machines
connected to the power source by fixed
conduit MUST be secured to the floor.

HAVE OIL INCLUDED!
Refer to the Lubrication
Section in this Manual
for Recommended
Oil Type.
The headstock, quick-change gearbox, and apron
oil reservoirs must have the proper amount of oil
in them before the lathe can be operated for the
first time.
Damage caused to the bearings and gears from
running the lathe without oil in the reservoirs
will not be covered under warranty. Refer to the
Lubrication section, beginning on Page 67, for
details on how to check and add oil.

In addition to the reservoirs, we also recommend
that you lubricate all other points on the
machine at this time. This can be accomplished
by following the maintenance schedule on
Page 65.
Note: If this lathe was shipped with oil in the
reservoirs, do not change that oil until after the
test run and break-in procedures.
Adding Coolant
Add the coolant of your choice now. For detailed
instructions on where the coolant tank is located
and how to add fluid, refer to Coolant System
Service subsection on Page 72.
Power Connection
After you have completed all previous setup
instructions and circuit requirements, the
machine is ready to be connected to the power
supply.
Model SB1054F & SB1055F
Due to the complexity required for planning,
bending, and installing the conduit necessary for
a code-compliant hardwire setup, an electrician
or other qualified person MUST perform this
type of installation.
Hardwire setups typically require power supply
wires to be enclosed inside of a solid or flexible
conduit, which is securely mounted at both ends
with the appropriate conduit fittings. All work
must adhere to the required electrical codes.
The hardwire setup must include a locking
disconnect switch (see Figure 25) between the
power source and the machine. This switch
serves as the means to completely disconnect
the machine from power to prevent electrocution
from accidental startup during adjustments,
maintenance, or service to the machine.

Connect a power cord that meets the Circuit
Requirements on Page 18, as instructed later
in this subsection. Attach a locking NEMA L1530 plug as directed by the plug manufacture,
and insert it into a matching receptacle
that is connected to a circuit that meets the
requirements listed on Page 18.
When removing the plug from the receptacle,
grasp it and pull it completely out of the
receptacle. Do not pull by the cord as this may
damage the wires inside.

electrical cabinet. The strain relief must be
tightened against the outer jacket of the
cord; however, avoid over-tightening the
strain relief or it may crush the cord and
cause a short.
Connecting Power
1. Make sure the master power switch is
turned to the OFF position, then open the
electrical cabinet door.
2. Refer to Figure 26 to identify the master
power switch and the hole at the bottom of
the electrical cabinet for the incoming power.
