The process is immersed in an electrolyte which allows the workpiece to be dissolved by accelerated corrosion resulting from electrochemical machining, which in this process does about 90% of the cutting. The remaining 10% is removed by the abrasive tool that uncovers non-corroded material faster, which accelerates the electrochemical machining.

Electrochemical grinding is often used for hard materials where conventional machining is difficult and time-consuming, such as stainless steel and some exotic metals. For materials with hardness greater than 65 HRC, ECG can have a material removal rate 10 times that of conventional machining.
Either electrochemical machining (ECM) or CNC milling can be the better choice, depending on the situation. PECM is advantageous as a non-contact, non-thermal process that is compatible with any conductive metal or alloy. With PECM, thin walls, speed, repeatability, and low surface roughness are all possible.
