Electrolyte grinding is a modification of both the grinding and electrochemical machining. In this process, machining is affected both by the grinding action and by the electrochemical process. Hence, in the true sense, it may be called 'mechanically assisted electrochemical machining. Working Principle of Electrochemical Grinding

Electrochemical machining is a process of removing metal with the help of the electrolysis process. The electrochemical process is also known as the reverse of the electroplating process because, in electroplating, the metal is deposited on the surface of the workpiece, while in electrochemical machining the metal is removed from the workpiece.

2.Electrochemical Grinding (ECG) 1.In ECG, the material removal is achieved by combined action of abrasive and electrochemical process energy. The resulting surface has high surface integrity, is burr free, and has negligible distortion. 2.The abrasive particles of the grinding wheel make a contact with the workpiece and the gap between the
