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.
Capabilities
This Heavy 13

EVS 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.

EVS (Electronic Variable Speed)
Lathe is packed with standard features and
equipment, such as an electronic variable speed
spindle control, a complete coolant system, easy-
to-clean chip drawer, one-shot way lubrication
system, steady and follow rests, chuck guard,
adjustable work lamp, foot brake, powered
cross feed, 3- and 4-jaw chucks, faceplate, and
premium Allen-Bradley electrical equipment.
Spindle speeds are controlled electronically with
the turn of a dial and readily visible on the top-
mounted digital display.
The bed is 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 quick-change gear levers
and the carriage includes a feed rod clutch that
disables automatic carriage feed when it contacts
the adjustable feed stop collar.
To ensure a high degree of accuracy and a long-
lasting operational life, this lathe is equipped
with Japanese spindle bearings. The spindle is
a D1-5 camlock with an MT#5 taper and 1.65"
bore. The tailstock has an MT#3 taper and 4.5" of
quill travel.
