摘要： An electric discharge machining apparatus is provided with an electrode mounting section which mounts a tool electrode, and an electrode driving section which has a radial driving section which supports and drives the electrode mounting section in a non-contact manner in a radial direction and a thrust driving section which supports and drives the electrode mounting section in a non-contact manner in a thrust direction, and a machining state is controlled by adjusting a position of the tool electrode by the electrode driving section. Because of such a structure, a mass increase of a section which should be driven together with the electrode is restricted, and high response in X-axis, Y-axis and Z-axis directions are achieved, whereby an electric discharge machining apparatus capable of improving a machining speed and a machining accuracy is achieved.
