Working of Electro Chemical Grinding a type of unconventional machining

Electro Chemical Grinding | Non-Traditional Machining Process

Electro chemical grinding is also called electrolytic grinding. Metal is removed from the surface of the work piece by electro chemical action and also by the abrasive action of a grinding wheel. 90% of metal is removed by electrochemical action and 10% of metal is removed by the abrasive action of the grinding wheel.
