摘要： A work rotating apparatus, for use in conjunction with a laser machine tool, comprises a frame, a rotatable shaft mounted on the frame for rotation on an axis, and a work mounting chuck supported by the shaft. A first disc is fixed to and rotates with the shaft. A second, stationary, disc is mounted on the frame in opposed relation to the rotatable disc. Recesses, formed on one of the discs, are positioned in circumferentially spaced relationship to one another, in a circle centered on the axis of the rotatable shaft. A spring-loaded ball detent is provided on the other disc for engagement with selected ones of the recesses. The work can be easily moved to each of several preset angles of inclination. A lock lever is provided to lock the shaft not only at the preset positions, but at any other desired position, so that any desired angle of inclination of the work can be achieved.
