ABSTRACT:
Apparatus for supplying a working fluid and a wire electrode to a wire region of a wire-cut electrical discharge machine comprising a housing supported by a support member and having opposed aligned openings through which a wire electrode is passed into operation association with a workpiece at the work region to be operated on by the electrode. A working fluid is supplied under pressure into the housing and the working fluid passes through a nozzle supported in the housing against the workpiece. The nozzle is positioned in the housing to surround the wire electrode which travels therethrough and it projects from the housing to discharge the working fluid against the workpiece at a gap formed therewith. A guide die is supported in the housing to guide the wire electrode through the housing and the nozzle. Electrical energy is supplied to the wire electrode before it enters the housing and a second nozzle is supported by the housing to discharge working fluid against the electrical supply system to cool the same.
