a wire electrode supplying apparatus for a wire electric discharge machine to effect the machining of a workpiece by inserting a wire electrode through the workpiece and allowing electric discharge to take place between the workpiece and the wire electrode . in this apparatus , a wire electrode feeding section is provided for inserting the wire electrode through the workpiece , as well as a feeding - side guide section and a receiving - side guide section are provided with the workpiece placed therebetween for the positioning of the wire electrode . the wire electrode is formed of a small - diameter wire , and the feeding - side guide section and the receiving side guide section are respectively provided with small openings for constraining the direction of its movement . the passage of the wire electrode through the small openings is aided by reducing the speed of feeding the wire electrode when the wire electrode passes through the small openings . a vertically movable jet nozzle is provided for allowing a working fluid to be jetted from the vicinity of the feeding - side guide section toward the receiving - side guide section so that the wire electrode after passing through the feeding - side guide section heads toward the receiving - side guide section . by starting the jetting of the working fluid after passing through the jet nozzle , the wire electrode is guided positively .
