Abstract
In a wire cut electrical discharge machining apparatus having an automatic wire feeder which feeds an electrode wire 10 through the material 12 to be machined automatically, electricity feeders 70 for supplying electrical energy for the machining operation to the wire 10 are disposed within a tubular guide 64 through which the wire 10 extends. The tubular guide 64 is improved in rigidity, and improved reliability is achieved in the supply of electricity to the wire.
