Abstract: An electrical discharge machining apparatus is provided with at least two work stations. A first servomotor is mounted above the first and second work stations, and a second servomotor mounted to the first servomotor so as to be selectively positioned over either of the first and second work stations by the first servomotor. The second servomotor is capable of causing relative motion between an electrode and a workpiece fixture in the first work station when positioned over the first work station and causing relative motion between an electrode and a workpiece fixture in the second work station when positioned over the second work station.
