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 lathes are a refined culmination of human ingenuity and knowledge embodied into the design and synergy of many different 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 carry on the tradition. As the operator of a South Bend Lathe, you join the ranks of some very famous and important customers, such as Henry Ford, who used his South Bend lathe to help him change the world.

Thank you for being a part of the new South Bend Lathe Co. We appreciate your business and hope this machine serves you well for a lifetime!

8" South Bend Precision Bench Lathe (Circa 1932)

8K™ Lathe

Dating back to 1931, the first South Bend 8" Bench Lathe made it much easier for machinists around the world to own a professional-duty lathe of exacting precision that was built to provide a lifetime of dependable service. In this same tradition, we are proud to offer the SB1001 8K Variable-Speed Bench Lathe.

This lathe is especially designed for discriminating machinists making small parts to extremely precise tolerances (jewelers, RC enthusiasts, watchmakers, model makers, optical engineers, gunsmiths, etc.).

Its compact size with heavy-duty construction and traditional South Bend “big lathe” features also make this lathe equally valuable for close-in precision toolroom or manufacturing operations.

The bed is constructed of hardened and ground castings in the traditional three V-way prismatic design—long used on South Bend Lathes for accuracy, durability, and rigidity. Its length allows for 18" between centers.

The headstock features a D1-3 variable-speed spindle that operates at 50–2300 RPM. Spindle speed changes are done very quickly and accurately with the convenient adjustment knob and digital display. Variable speed control allows the operator to “dial in” the perfect cutting speed for super-fine finishes.

The carriage has longitudinal power feeding capabilities with 9 available feed speeds ranging from 0.003"–0.0051"per revolution.

The South Bend 8K is capable of cutting inch or metric threads—12 inch threads from 10–32 TPI and 12 metric threads from 0.4–3.0mm.

Accessories include a heavy-duty tailstock, a

4-way tool post, MT#2 dead center, MT#3 dead center, and 3-jaw scroll chuck.
