PURPOSE:To supply a sufficient amount of machining fluid to a machining gap, by providing machining fluid supply nozzles so that the nozzle crosses at an angle within 15 deg.C with respect to a wire electrode. CONSTITUTION:An electric discharge machine, feeding out a wire electrode 3 from a wire electrode supply drum 1, positions the wire electrode 3 in its machining part by a pair of positioning guides provided in a position relatively approaching to both sides of a work 4, and the used wire electrode 3 is wound onto a wire electrode collecting drum 2. Machining fluid supply nozzles 5, 5, whose point end part is positioned to a side of the work 4 from the positioning guide, are provided in a part of the main unit of the wire cut electric discharge machine so that the nozzle 5 crosses at a desired angle within 15 deg. with respect to the wire electrode 3. |
