ABSTRACT:
A multi-spindle machine tool comprises a frame mounting an indexable work spindle carrier which carries a plurality of rotatably mounted work spindles, and a workpiece gripper mounted on each spindle and including an actuating element movable axially of the associated spindle to open and close the workpiece gripper. A ring surrounds all of the spindles and is angularly movable about an axis coincident with the axis of the carrier, and a cam surface on said ring co-acts with said actuating elements whereby the grippers can be opened and closed by a sequence of operations including angular movement of the ring and indexing of the spindle carrier.
