( electrical discharge machining) involves the removal of metal from a workpiece by sending an electric current through an electrode or wire. The principle is the same for wire erosion, die-sinking and micro-drilling. This technique ensures perfection in terms of dimensions and surface finish regardless of the type of metal being machined. Once a micro-hole has been drilled, the wire can be passed through the workpiece and the erosion of the metal can take place.
