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
Looking down the bore of the Big Bore Lathes is
like looking straight down the barrel of a huge
cannon. With an extra-large 9" spindle bore and
inside/outside spindle noses for mounting chucks
on both sides of the headstock, these lathes can
handle monster-sized workpieces such as large-
diameter oil pipes or hydraulic cylinders. They
are exquisitely built with ultra-tight tolerances,
and the headstocks and gearboxes are assembled
in a laboratory-like environment to ensure
absolutely pristine bearings and fittings for a
lifetime of rugged use. Each lathe is built to
order with chucks precision-fitted onto the lathe
at the factory.
The beds of these lathes are constructed with
Meehanite castings that are hardened and
precision-ground in the traditional three V-way
prismatic design—long used on South Bend
Lathes for its accuracy, durability, and rigidity.
The headstock features gear levers, and the
carriage includes an adjustable clutch that
disables automatic carriage feed when it contacts
the included 4-position apron stop or in the event
of a crash.
To further ensure a high degree of accuracy,
these lathes are equipped with high-quality
spindle bearings and a Fagor DRO. The spindle
nose is A2-15 with an MT#7 taper. The tailstock
has an MT#6 taper and 10" of quill travel. For
easy end drilling of large diameter holes and
chamfers with the tailstock handwheel, a 2-speed
gearbox is incorporated in the tailstock.
Also included is a remote-mounted control panel
on the carriage, and a rapid traverse motor with
controls for moving the cross and longitudinal
feeds for quick tooling positioning and returns.
These lathes are equipped with two types of
brakes: a band-style foot brake and an electric
motor brake.
Capabilities
These Big Bore Lathes are built for daily use
in busy gas and oil field settings. Loaded with
many nice features and high-precision parts,
these lathes excel when long drill pipes, shafts,
and flanges need to be surfaced, chamfered,
or threaded. Thick castings, heavy mass, and
quality construction throughout provide the
necessary brawn for demanding production and
manufacturing tasks.

Model SB1065F–SB1071F SAFETY
Additional Metal Lathe Safety
Rotating Parts. Always keep hands and body
at a safe distance from rotating parts—
especially those with projecting surfaces.
Never hold anything against rotating
workpiece, such as emery cloth, that can
pull you into lathe.
Guarding. Guards and covers protect against
entanglement or flying objects. Always
ensure they are properly installed while
machine is running.
Adjustment Tools. Remove all chuck keys,
wrenches, and adjustment tools before
turning lathe ON. A tool left on the lathe
can become a deadly projectile when
spindle is started.
Safe Clearances. Before starting spindle, verify
workpiece has adequate clearance by
hand-rotating it through its entire range of
motion.
New Setups. Test each new setup by starting
spindle rotation at the lowest speed and
standing to the side of the lathe until
workpiece reaches full speed and you can
verify safe rotation.
Spindle Speeds. Using spindle speeds that
are too fast for the workpiece or clamping
equipment can cause rotating parts to come
loose and strike nearby people with deadly
force. Always use slow spindle speeds with
large or non-concentric workpieces. Never
exceed rated RPM of the chuck.
Long Stock Safety. Long stock can whip
violently if not properly supported. Always
support any stock that extends from the
chuck/headstock more than three times its
own diameter.
Clearing Chips. Metal chips can be razor sharp.
Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.
Chucks. Chucks can be heavy and difficult to
hold. During installation and removal,
protect your hands and precision bed ways
by using a chuck cradle or piece of plywood
over the bed ways. Use lifting equipment,
as necessary, for large chucks.
Stopping Spindle. Always allow spindle to
completely stop on its own, or use a brake,
if provided. Never put hands or another
object on a spinning workpiece to make it
stop faster.
Crashing. A serious explosion of metal parts
can occur if cutting tool or other lathe
component hits rotating chuck or a
projecting part of workpiece. Resulting
metal fragments can strike nearby people
and lathe will be seriously damaged.
To reduce risk of crashing, ALWAYS
release automatic feeds after use, NEVER
leave lathe unattended, and CHECK all
clearances before starting lathe.
Coolant Safety. Coolant can become very toxic
through prolonged use and aging. To
minimize toxicity, change coolant regularly.
When using, position nozzle properly to
avoid splashing operator or causing a
slipping hazard on floor.
Tool Selection. Cutting with incorrect or dull
tooling increases risk of injury from broken
or dislodged components, or as a result of
extra force required for operation. Always
use sharp tooling that is right for the job.
Sanding/Polishing. To reduce entanglement
risk, never wrap emery cloth around
rotating workpiece. Instead, use emery
cloth with the aid of a tool or backing
board.
Measuring Workpiece. To reduce risk of
entanglement, never measure rotating
workpieces.
Serious injury or death can occur from getting entangled in, crushed between, or struck
by rotating parts on a lathe! Unsecured tools or workpieces can eject from the chuck and
strike nearby operators with deadly force. To minimize the risk of getting hurt or killed,
anyone operating this lathe MUST follow the hazards and warnings below.

SAFETY
Additional Chuck Safety
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.
Chuck Speed Rating. Excessive spindle speeds
greatly increase the risk of the workpiece
or chuck being thrown from the machine
with deadly force. Never use spindle speeds
faster than the chuck RPM rating or the
safe limits of your workpiece.
Using Correct Equipment. Many workpieces can
only be safely turned in a lathe if additional
support equipment, such as a tailstock or
steady/follow 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.
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 a chuck.
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.
Proper Maintenance. All chucks must be
properly 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.
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.

Power Supply
Requirements
Availability
Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.
To minimize the risk of electrocution, fire,
or equipment damage, installation work and
electrical wiring must be done by an electrician
or qualified service personnel in accordance with
all applicable codes.
Circuit Information
For your own safety and protection of property,
consult an electrician if you are unsure about
wiring practices or applicable electrical codes.
A 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. (If this machine is
connected to a circuit protected by fuses, use a
time delay fuse marked D.)
Circuit Requirements 230V/460V
This machine is pre-wired to operate on a 230V
power supply circuit. With the SB460VSB1065F
conversion kit installed, the machine will operate
on 460V. Under both options, this machine must
have a power supply circuit that has a verified
ground and meets the following requirements:
Nominal Voltage ............................... 230V/460V
Cycle .............................................................60 Hz
Phase ....................................................... 3-Phase
Minimum Circuit Rating .............. 90/50 Amps
Connection ........Hardwire w/Locking Switch
Note: The circuit requirements in this manual
are for
a dedicated circuit—where only one
machine will be running at a time. If this
machine will be connected to a shared circuit
where multiple machines will be running at
the same time, consult a qualified electrician to
ensure the circuit is properly sized.
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.
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.
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.
Full-Load Current Rating
Full-Load Rating at 230V 3-PH......71.6 Amps
Full-Load Rating at 460V 3-PH......35.8 Amps

Grounding Requirements
This machine must be grounded! 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 power cord repair or replacement is necessary,
do not connect the equipment-grounding 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.

Unpacking
This item was carefully packaged to prevent
damage during transport. If you discover any
damage, please immediately call Customer
Service at
[phone] for advice. You may
need to file a freight claim, so save the containers
and all packing materials for possible inspection
by the carrier or its agent.
Inventory
This class of lathes is built specifically to order.
To verify that your shipment is complete, please
compare your order with the bill of materials
sheet from the crate.
Note: Additional documentation pertaining to
the electrical system is shipped inside of the lathe
electrical cabinet.
IMPORTANT: DO NOT use a static phase
converter to create 3-phase power—it can quickly
decrease the life of electrical components on this
machine. If you must use a phase converter, only
use a rotary phase converter.
When connected to a rotary phase converter,
power from the manufactured power
leg (sometimes called 'the wild wire' or
'manufactured leg') can fluctuate. Make sure that
when you connect the lathe to the phase converter
you connect the wild wire to the lathe input
lead L2, and that L1 and L3 incoming power
do not fluctuate. Fluctuation of power to the
transformer may cause magnetic switch chatter
and transformer damage and prevent the lathe
from starting correctly.
Phase Converter
As specified in the Circuit Requirements
section on the previous Page, this machine must
be hardwired to the power source, using a locking
switch (see Figure 12).
This machine must also be connected to a
grounded metal permanent wiring system; or to a
system with an equipment-grounding conductor.
Due to the complexity and high voltage involved,
this type of installation MUST be done by an
electrician or qualified service personnel.

PREPARATION
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, the
following
process works well in most situations
.
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

Before using these products, though, test them
on an inconspicuous area of a painted surface 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.
Cleaning & Protecting
Open the end gear cover and clean the end
gears using a stiff brush with mineral spirits.
DO NOT get any cleaner or rust preventative
on the V-belts or the brake band lining, as it
could damage them or make them slip during
operations.
