摘要： The present invention relates to a compound electrical discharge machining (EDM) apparatus, which combines a small-hole EDM module and a wire-cut EDM apparatus and hence having the functions of small-hole and wire-cut EDM simultaneously. Thereby, in the compound EDM apparatus, a workpiece can be first processed by the small-hole EDM and subsequently by the wire-cut EDM without repositioning. Accordingly, automatic processing can be achieved. The inability of full automation in wire-cut EDM machines owing to lack of small-hole EDM functionality is improved.

摘要： A water purifying unit generates pure water by eliminating impurity ions from dielectric fluid. A corrosion-protection-ion generating unit generates corrosion protection ions, substitutes predetermined cations for impurity cations contained in the dielectric fluid, and substitutes the corrosion protection ions for impurity anions contained in the dielectric fluid. A switching unit switches a supply of the dielectric fluid between the water purifying unit and the corrosion-protection-ion generating unit. A switching control unit controls the switching unit based on a conductivity of the dielectric fluid measured by a conductivity measuring unit.
