Apr 12, 2017· Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine …
Electrical Discharge Machining. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. From: Machining and machine …

Machine tool - Machine tool - Electrical-discharge machining (EDM): EDM involves the direction of high-frequency electrical spark discharges from a graphite or soft metal tool, which serves as an electrode, to disintegrate electrically conductive materials such as hardened steel or carbide. The electrode and workpiece are immersed in a dielectric liquid, and a feed mechanism maintains a spark ...
Each grinding wheel is composed of a conductive grindstone having abrasive grains bound by a conductive binding material. An electrode discharge is applied from an electro-discharge truing electrode disposed in the space between the grindstone surfaces in a non-contacting relationship with the grindstone surfaces.

Electro Chemical Grinding (ECG) Electrochemical grinding combines both electrolytic action (90%) and physical grinding (10%) to provide precision, burr-free and stress-free results. Owing to the electrolytic reaction, ECG eliminates the need for a separate deburring operation.
Dec 15, 2017· Because the electrical discharge erodes by the wire and the workpiece, wire EDM machines use a spool of wire that's continuously moving to present a fresh discharge path in the cut. This "cheese cutter" approach to EDM works well, but it has an important limitation: the wire must pass entirely through the workpiece, making an essentially ...
