ABSTRACT:
A work rotating device for use with a laser beam machine tool comprises an L-shaped frame from which a servo motor, speed reducer, and a rotatable work holder are supported in cantilever fashion by a shaft rotatable in bearings provided in a hole in the frame. The shaft has an end plate haivng a spring-loaded indexing pin engageable with any selected one of several indexing holes in an indexing plate fixed to the frame. The angle of inclination of the axis of rotation of the work is read from a scale on the end plate, by means of an indexing mark on the indexing plate. The indexing plate and end plate exert axial pressure respectively on outer and inner rings of the bearings to eliminate play.
