Definition
Electrochemical grinding (ECG) is a hybrid process combining grinding and ECM, which uses a grinding wheel as electrode to remove electrically conductive material. Direct current (DC) flows through an electrolyte between the negatively charged grinding wheel and the positively charged workpiece. Material removal takes place through the combination of mechanical and electrochemical processes, acting on the same area at the workpiece. Advantages of this hybrid machining process result from interaction between micro-cutting and electrochemical dissolving, both processes acting in a surface layer of the workpiece.
Theory and Application
In ECG processes, schematically shown in Fig. 1, the rotating grinding wheel acts as cathode (negatively charged) which provides the desired shape of the workpiece. The workpiece is connected to the positive pole of a DC power supply. The electrolyte fluid, such as sodium...
