ABSTRACT:
A machine tool having a tool-supporting hollow spindle has the tool mounted in fixed relation to a draw bar which slides axially within the spindle between a tool retaining position and a tool release position. A barrel cam within the spindle is adapted to be engaged and rotated by a cam driver member secured to an actuating shaft longitudinally movable within the spindle. The spindle rotates with the cam until a predetermined angular position is reached, after which additional longitudinal movement of the actuating shaft causes movement of the draw bar downwardly within the spindle from its tool retaining position to its tool release position, where the tool is resiliently supported until it is removed, either manually or by automatic means.
