To enhance machining efficiency, tool exchange time have to be reduced. Most automatic tool changer is made up of compound cam and motor. it is not easy to design and manufacture compound cam, and it has no flexibility. But if servo motor is used, it is easy to changer is developed with servo motor, clutch, ball-screw and spline nut. Experimental results show that automatic tool changer designed with servo motor have good faculties.
