Congratulations on selecting the OTMT SC4
Bench Lathe (SC4). You have chosen a
precision machine tool that can perform a wide
range of complex and precise lathe operations.
With proper maintenance and care, it will
provide many years of service.
have any questions regarding the operation of
your lathe, please contact Travers Technical
Support for assistance.

The purpose of this manual is to familiarize the
lathe operator with the installation and controls
of the machine and basic lathe procedures. To
become proficient in using the lathe, the
operator should seek in-depth training using
reference books, resources available on the
technical schools or from an operator already
skilled in the use of a similar lathe.
Capabilities of the Lathe
A precision metal-working lathe is one of the
most useful and productive tools in the
capability to produce cylindrical and tapered
shapes with very accurate dimensions in a
wide variety of materials such as steel, brass,
aluminum and many plastics. With appropriate
tooling it is even possible to create round,
concave and cubical shapes on the lathe.
The SC4 lathe is equipped with a powerful
1000-watt brushless DC motor with electronic
speed control, providing strong torque at all
speeds, electronic braking and instant direction
reversal for operations such as tapping. The
PDF created with pdfFactory Pro trial version
motor is completely sealed from dirt, dust, oil,
metal chips and other shop contaminants and
is permanently lubricated and maintenance-
While the ultimate precision of a finished
workpiece depends on many factors, such as
the material, shape of the cutting tool, proper
adjustment of the lathe and skill of the lathe
operator, dimensions of one-one-thousandth of
an inch (0.001") or better are possible.
With the provided set of change gears, power
feed rates may be adjusted and a wide range
of both metric and SAE external and internal
threads can accurately be cut. The optional
milling head accessory
adds light vertical milling and precision drill
press capabilities to the SC4.
