Difference Between CHM and ECM - Chemical ...

In Electro-Chemical Machining (ECM), material is removed by ionic dissolution but under the assistance of electro-chemical reaction. No corrosive etchant is used here; instead, a suitable electrolyte is employed. ECM requires a shaped tool made of electrically conductive material that is placed close to the workpiece (a small gap is maintained).

New Applications for Electrochemical Grinding | Modern ...

Although it has experienced a steady growth, electrochemical grinding (ECG) is mostly known as a niche process. Developed in the 1930s, it became popular in the US in the 1950s for grinding carbide cutting tools. At the time, the only other way to grind carbide was with an expensive, natural diamond grinding wheel.
