摘要

A crankshaft lathe of the single spindle pin type capable of universal use with a variety of types of crankshafts. The lathe includes a single tool support mounted upon ways for movement both perpendicular and parallel to the workpiece axis. A single drive motor powers both workpiece rotation and tool movement through an indexable connection wherein the relative angular relationship between workpiece and tool drive is adjustable. Automatic controls permit the lathe to individually machine the pins sequentially of a multiple pin crankshaft.
