ABSTRACT:
A combination magazine and changer for use with a machining head of an electrical discharge machine for rapidly changing a tool. The magazine includes a plurality of separate housings, each of which supports a tool. A retaining means is provided for each housing and creates an attracting force for holding the tools in place. The changer includes a robot arm arranged in proximity to the magazine and which is capable of linear motion relative to the magazine. A mechanical clamping member is mounted to an end of the arm and removes a given tool from the magazine for use in the machining head in a first linear motion and replaces the used tool on the magazine in a second reverse linear motion.
