Electrochemical grinding Electrochemical process in which a grinding wheel of abrasive material rotates along with the surface that is covered with an electrolyte and in which both the electrolyte and the abrasive wheel contributes to the grinding. The process By connecting to a power source, the workpiece acts as anode and the tool as cathode.

Electrochemical grinding (ECG) joins electrochemical machining with regular grinding. The gear utilized is like an ordinary processor. The wheel is a pivoting cathode installed with grating particles. The wheel is metal bonded with diamond or aluminum-oxide abrasives and turns at a surface speed from 1,200 to 2,000 m/min (4,000 to 7,000 ft/min).

Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).

electrochemical forming process. The noteworthy feature of electrolysis is that electrical energy is used to produce a chemical reaction, therefore, the machining process based on this principle is known as Electrochemical machining (ECM). This process works on the principle of of Faraday's laws of electrolysis.
