Numerous tiny holes appears due to erosion of impulse discharging, and therefore get the needed shape of workpiece( as show in figure 1-1). In addition to wire EDM, the same principle is used today in diesinker, or vertical EDM, which makes a cavity in the work piece using a copper or graphite electrode in the desired shape. Wire-cut EDM - Working principle In EDM wire-cutting machines, a thin single-strand metal wire (usually made of brass) is fed through the workpiece, submerged in a tank of dielectric fluid. Those guides are usually CNC controlled and can move on a x-y axis. Suitable for high precision taper processing, high precision parts processing etc. Kashif Ishfaq et al. Brad's experience in machinery sales provides our customers a wealth of know-how. Electrodes for Spark EDM are mostly manufactured from graphite or copper tungsten. A beam of electrons is emitted from the electron gun which is a triod consisting of: A cathode is a hot tungsten filament (2500°C) emitting high -ve potential electrons.
