General Operating Instructions

Every ten hours of operation, lubri- cate the lathe’s gears and ways with white lithium grease, as directed in the Mainte- nance Section of this manual.

1.The Lathe can perform a wide variety of operations; the purchase of refer-

ence materials, such as books about machining or engineering tables, is highly recommended.

2.If Lathe use requires a higher de- gree of accuracy than supplied by the standard set-up, have the Lathe serviced by a qualified machinist.

3.Settings for the spindle, chuck, gibs, ways, and ends, will be determined by the length of the stock and the intended operation.

4.Turn the chuck by hand to make sure it rotates smoothly.

5.Plug the Lathe into a standard, grounded 120V electrical outlet.

General Milling Guidelines

1.When performing any operation with the Lathe it is best to proceed slowly and make several passes.

2.A 1000th of an inch of movement yields a 2000th inch cut.

3.Use of a high-quality cutting fluid (not included) will greatly aid in most mill- ing processes.

Facing Operations

Facing is the process of removing metal from the end of a workpiece to pro- duce a flat surface.

1.To safely perform a facing operation the jaws of the chuck must be as close as possible to the end of the workpiece. The workpiece should not extend more than 2 or 3 times its diameter from the chuck jaws unless the steady rest is used to support the end of the workpiece.
