EDM Laboratories Inc. Company Profile

EDM (electric discharge machining) is a process which removes metal by vaporizing it with a spark. Anyone who has ever dropped a wrench across a car battery has witnessed a very crude form of EDM. The modern EDM process uses high frequencies, sometimes creating hundreds of thousands of tiny sparks per second. A servo motor changes the feed rate of the electrode to keep the voltage constant and a dielectric fluid serves the purposes of acting as a dielectric barrier to allow the charge to build up, a coolant to prevent the electrode from getting hot, and removing the vaporized...
