What is EDM?
| Author : Polcraft inc Date : 2012/7/13 5:50:01 |
EDM stands for Electrical Discharge Machining. A media of electrode is used to erode a workpiece using electrical sparks. The electricity flows through the electrode in the form of a square wave attacking the points of least resistance on the workpiece similar to how a bolt of lightning would hit a tree before it hits the ground. This "Zap" happens every time the current is switched on in the square wave and then the current is switched off to allow the debree to be flushed away. This process happens over and over many times a second as the electrode is slowly advanced deeper and deeper into the cut. The electrode never touches the workpiece because the actual cutting is being done by the spark gap between the electrode and the workpiece.
Electrical Discharge Machining is a very precise and demanding process. Any product required for the operation of an EDM must demonstrate high quality standards. Understanding this demand for quality, many of these products can be manufactured with the know-how obtained from many years of hands-on EDM experience.
