About These Machines

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 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.

Capabilities

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.

Features

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.
