ABSTRACT:
A wire-cut electric discharge machine having an improved nozzle system for supplying working fluid into a working gap between a workpiece and wire electrode. The improved nozzle system comprises a working fluid nozzle coaxial with the wire electrode and an auxiliary nozzle for producing an intense jet stream in the back portion of the wire electrode, namely, into the slit formed by the spark erosion. The jet stream pressure acts on the semicylindrical surface opposite the front surface at which the discharge pressure is produced to preserve the linearity of the wire electrode.
