Grinding - Memry

Abrasive grinding is an ideal alternative to conventional machining because of the high ductility and rapid work hardening of the material. Electrochemical grinding (ECG) combines the precision of abrasive grinding with the low force qualities of electrochemical erosion.The process limits physical stresses, mechanical damage, and heat affect inherent to more conventional processes.

Chemical and Electro Chemical Energy Based Processes

Electrochemical Grinding (ECG) is a combination of electrochemical (Anodic) dissolution of a material, according to Faraday's Law, and light abrasive action. The metal is decomposed to some degree by the DC current flow between the conductive grinding wheel (Cathode) and the work piece (Anode) in the presence of an electrolyte solution.
