EVS Toolroom Lathes

-3-

"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 lathes represented in this manual are 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.

As the name implies, these lathes feature EVS 
(Electronic Variable Speed) spindle control, 
which allows the operator to quickly set the 
exact spindle speed within the available range of 
20–2500 RPM. Spindle speed is displayed on a 
digital readout and controlled within each speed 
range with the use of a dial—no changing gears 
or looking up complex lever positions on a chart.

The beds of these lathes are constructed with 
Meehanite castings that have been precision 
hardened and ground in the traditional 3-V 
prismatic design—long used on South Bend 
Lathes for its accuracy, durability, and rigidity.

The headstock features quick-change gear levers 
and an adjustable clutch mechanism for the feed 
rod that can be set to prevent damage in the 
event of a crash.

To further ensure a high degree of accuracy, 
these lathes are equipped with NSK or NTN 
spindle bearings. The spindles are the D1-6 
camlock type with an MT#6 taper and 2.0625" 
bore. The tailstock quills have an MT#4 taper 
and offer 6" of travel.

The EVS lathes also include a pressurized 
headstock oiling system that pre-lubricates 
bearings/gears before the spindle starts and 
delivers perfect lubrication during low speed 
operations (compare to conventional splash 
and bath oil systems that leave bearings/gears 
starved for oil when the spindle is first started 
and during low speed operations).

Finally, these EVS toolroom lathes are packed 
with standard features, such as a complete 
coolant system, easy-to-clean chip drawer, one-
shot way lubrication system, included steady and 
follow rests, adjustable work lamp, foot brake, 
and powered cross feed.

These EVS Toolroom 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.
