We sometimes combine EDG (Electrical-Discharge Grinding) process with ECG (Electrochemical Grinding) process where material is removed by chemical action, the electrical discharges from the graphite wheel breaking up the oxide film and washed away by the electrolyte. The process is called ELECTROCHEMICAL-DISCHARGE GRINDING (ECDG).

2013-11-1 The mechanism of material removal in electric discharge grinding (EDG) is very complex due to interdependence of mechanical and thermal energies responsible for material removal. Therefore, on the basis of conceived process physics for material removal, an attempt has been made to predict the material removal rate (MRR).

Both wire electro-discharge grinding (WEDG) and electro-discharge grinding (EDG) with wire and disc electrodes were applied for fabricating radii and sharp corners, respectively. For example, when the coaxial hole with a groove is machined, first the cylindrical electrode is used for boring the hole by EDM, and next the electrode is reformed into a special plug shape to make the inside groove.

2017-4-23 Electric Discharge Grinding (EDG) EDG is similar to EDM except that the electrode is a rotating wheel (usually graphite). Positively charged work pieces are immersed in or flooded by a dielectric fluid and fed past the negatively charged wheel by servo-controlled machine table. Metal is removed by intermittent high frequency electrical discharges passing through the gap between wheel and workpiece. Each spark discharge

2019-2-20 Similar to cutting EDM, Electric discharge grinding (EDG) uses a rotating wheel as an electrode instead of wire as an electrode in the mechanism of metal removal. Micro-EDM is a process where workpiece is usually below 1mm size, it delivers high precision and very fine micro detailing [ 23 ].
Read More2012-4-28 Electro-Discharge Machining (EDM) is machining with sparks. The work-piece is held in a jig submerged in a dielectric fluid such as kerosene. A power supply generates rapid electric pulses that create a discharge between the work piece and an electrode (a continuous wire or a shaped graphite form) at the point at which the two are closest.
