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
These Turn-Nado ® Gearhead Lathes are built
for daily use in a busy industrial setting.
Loaded with many nice features and high-
precision parts, these lathes excel at making fine
tools, dies, thread gauges, jigs, and precision
test gauges—however, they are by no means
delicate. Thick castings, heavy weight, and
quality construction throughout provide the
necessary brawn for demanding production and
manufacturing tasks.
Features
These 16-Speed Gearhead Lathes are 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, faceplate, and
premium Allen-Bradley contactors, thermal
relays, and fuse system.
Spindle speeds are controlled by convenient
headstock levers, which allow the operator to
quickly set the spindle speed within the available
range of 20–1600 RPM.
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 headstocks feature quick-change gear levers
and the carriages include an adjustable clutch
that disables automatic carriage feed when it
contacts the included feed stop or in the event of
a crash.
These lathes feature a spindle clutch that allows
the operator to switch between forward and reverse
without shutting down the motor—a great time saver.
To further ensure a high degree of accuracy,
these lathes are equipped with high-quality
German spindle bearings and a Fagor 2-Axis
DRO. The spindles are D1-8 camlock with an
MT#7 taper and 3.15" bore. The tailstocks have
an MT#5 taper and 6.5" of quill travel.
