Wheel Type — While different wheels can be used in electrochemical grinding, the wheel must be conductive. Thus, the grinding wheel is similar to traditional bonded abrasive particle wheels but unique to the process, the wheel is infused with high amounts of copper to make it conductive.
This process is a combination of the traditional grinding process and the electrochemical machining process. The electrochemical grinding process is also popularly known as electrolytic grinding or anodic machining. The material is removed by the action of the grinding wheel as well as by a chemical reaction.
PROCESS OF GRINDING IN ECM The main feature of electrochemical grinding (ECG) process is the use of a metallic grinding wheel which is embedded with insulating abrasive particles such as diamond, set in the conducting material. Copper, brass, and nickel are the most commonly used materials while aluminum oxide is a typical abrasive used while ...
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).
As the grinding wheel is the cathode within our electrochemical cell, the abrasives are present to assist in the removal of non-conductive elements. The electrochemical action grinding swarf is a fine particulate (anode mud) that does not adhere to the perishable during the grinds.

E = E. a - E. c, where . E. a. and. E. c. are the overpotential
Electrochemical grinding is a combination of electrochemical machining and grinding processes. The major difference between ECM and ECG is that In ECG grinding wheel is used instead of a cutting tool. Electrochemical grinding is done when there is a need to remove the material from the surface of the workpiece.
The electrochemical grinding process typically embodies a grinding wheel which uses an electrically conductive abrasive and bonding agent. The electrolyte is introduced to the work area in the same manner that coolant would be introduced in conventional wet grinding operations. This topic seeks to develop an electrochemically assisted precision ...
