Abstract
An electric discharge wire cutting machine with one nozzle above the workpiece and another nozzle beneath the workpiece, one of the nozzles having a shape obtained by rotating an arc of a circle about the central axis of the conical configuration of the nozzle. This shape allows the working fluid to be smoothly expelled and to prevent the formation of gas bubbles by the wire in the working zone which might prevent adequate cooling of the wire and thereby cuase the wire to break.
