Abstract

A wire electrodischarge machine comprises a cross table on which a workpiece is mounted and which is driven in a horizontal plane. In X and Y directions, upper and lower dielectric fluid nozzles which are disposed above and below the workpiece, a nozzle drive device for driving one of the upper and lower nozzles within a horizontal plane, in U and V directions, in order to conduct taper machining, and a verical shaft for supporting the nozzle drive device and the above-mentioned one of the upper and lower nozzles. The axis of the nozzle which is driven by the nozzle drive device is disposed, even during the taper machining, within the area defined by the periphery of the vertical shaft at which the vertical shaft is supported such that it can slide vertically.
