Wire electric discharge machine
First Claim
1. A wire electrical discharge machining apparatus in which a working fluid is interposed between a wire electrode and a workpiece to machine the workpiece by electrical discharge, comprising:
- an upper guide and a lower guide which are respectively disposed above and below the workpiece and respectively incorporate wire guides for guiding said wire electrode;
a nozzle for jetting and supplying the working fluid from at least one of said upper guide and said lower guide toward the workpiece; and
a pump for supplying the working fluid to said nozzle, wherein a gas is mixed into the working fluid on an upstream side of said pump, and the working fluid in a state of a gas-liquid mixed phase is jetted and supplied from said nozzle to the workpiece.
