ABSTRACT:
In a workpiece support for use with a laser beam machine tool, in which the workpiece is rotated about an axis tiltable through 90.degree. or more to either side of a vertical condition, the workpiece is held by a chuck driven through a right-angle speed reducer by a servomotor. The chuck, reducer and motor are all supported on a shaft rotatably mounted in bearings on a frame. The shaft is coupled to a disc having angle markings and lockable at discrete rotational positions on the frame. Fine adjustment of the rotational position of the shaft relative to the disc is effected by engagement of an offset protrusion on the end of the shaft by a screw-shifted operating member on the disc. Two such operating members are provided in opposed relationship on opposite sides of the protrusion so that they can be used to lock the shaft and disc securely together.
