Electrical Discharge Machining (EDM) is an electro thermo process that uses a thin metal wire (wire EDM) along with de-ionized water. With wire EDM, high-pressure water is used to conduct electricity and to flush away particles. The EDM process removes metal by producing a rapid series of electrical discharges, sometimes called “Spark Machining.” The EDM method allows for precision machining out of hard conductive materials. The method works for complex machining in any metal including steel, titanium, hastelloy and kovar.

 The precision machining from EDM equipment is a common process for machining components for aerospace, gas turbines, medical, automotive and anywhere else complex precision machining is required. Machines run constantly and require dependable components to avoid costly breakdowns.
