ABSTRACT:
A tool exchanger for programmed machine tools includes a device for the conveyance of selected tools between a tool room and a main spindle of the machine tool and with two grip devices moving along a prescribed rotation angle and arranged in a carrier support mounted to the conveyance device and able to rotate between an alternate position and at least one standby position. In order to achieve faster exchange operations of the tools in a horizontal and vertical machining spindle, the drives to open and close both tool grips are activated at the same time. The support mounted includes a locking device which blocks the tool grip to standby position in its closed condition.
