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. It is also a low stress machining operation that avoids potential ...

Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject ...

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...

Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermoelectric energy between the workpiece and an electrode. Material removal rate (MRR) is an important performance measure in EDM process. Since long, EDM researchers have explored a number of ways to improve and optimize the MRR including some unique experimental ...

Abrasive Electrical Discharge Grinding (AEDG) . Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of Al-SiC composite, removal rate of the AEDG process (t e = 10 m s, and n = 500 rpm) is about 5 times greater than that of EDM process, and about twice of EDG process.

Electrical discharge machining (EDM) is a new technology that uses electric energy and heat energy to process. The difference between electrical discharge machining and general machining is that the tool and workpiece are not in contact during electrical discharge machining. Instead, the metal material is gradually eroded by the pulse spark discharge generated between the tool and …
