However, in ECM-based combined processes (such as electrochemical grinding (ECG), electrochemical discharge machining), both ECM and the other processes participate in material removal. The resulting synergetic effect is a 1+1=3 effect which implies that the combined effect of ECM with other process energy is more than double the benefits of ...
Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...

Electrochemical grinding is capable of achieving a surface of Ra 16 µin (0.41 µm). However, unlike with traditional abrasive grinding, the finish is matte rather than highly polished. While electrochemical grinding works with different metals, the material that is being ground must be conductive and electrochemically reactive.

The basic components of the process are a conductive grinding wheel, typically made of a matrix of copper, abrasive and resin, a tank that holds an electrolytic solution, and a direct current power ...
Basically, it is a combination of an electrochemical process and a grinding process used for metal removal. You may also hear it referred to as "anodic machining" or "electrolytic grinding". In the process, the part of a cathode is played by the grinding wheel, while the role of an anode is played by the workpiece.
