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 
1
16
" bore. Tailstock quill has an 
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.
