Electro Chemical Grinding (ECG) Electrochemical grinding combines both electrolytic action (90%) and physical grinding (10%) to provide precision, burr-free and stress-free results. Owing to the electrolytic reaction, ECG eliminates the need for a separate deburring operation.
Electrochemical Grinding (ECG) Electrochemical grinding (ECG) is a combination of ECM and the grinding process. The metal is removed both by anodic dissolution as in ECM and abrasion by the grinding wheel. In this process, both the grinding wheel and the work piece have to be conductors of electricity. The grinding wheels employed are in general metal (phosphor bronze)-bonded diamond …
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.
