Method and apparatus for electrodischarge wire machining

摘要

A wire electrical discharge machining apparatus for machining a workpiece (2) by supplying electric discharge energy to a gap between a wire electrode (1a) and the workpiece (2) by machining-electric-power supplying means and by relatively moving the wire electrode (1a) and the workpiece (2) by positioning means has fluid supplying means (12) in which a working-fluid supplying means for supplying a working liquid (4a) to the gap, a mist supplying means for supplying a mist (7) to the gap, a gas supplying means for supplying a gas (8) to the gap, and a cooling-fluid supplying means for supplying the working liquid (4a) which is a cooling fluid for cooling the workpiece (2) are combined and are formed integrally. It is possible to effect wire electrical discharge machining which is suitable for attainment of higher accuracy and higher quality.
