Electrochemical grinding is a reverse of electroplating. In this, the metal surface is converted into its respective oxide which is then removed by the rotating grinding wheel. Only 5-10% of the material is removed by the Abrasive grinding wheel, the rest is removed by the flow of electrolyte. Parts or Construction of Electrochemical Grinding:

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.

It can be seen from Fig. 6a that the minimum distance between workpiece and grinding wheel matrix is always kept at 40 μm, demonstrating that the abrasive particles of the grinding wheel are involved in the material removal process. Besides, due to the electrochemical corrosion, part of the workpiece is dissolved before grinding.
