ECG is a hybrid process combining electrochemical machining and grinding. Electrochemical machining is an electrolytic operation where the workpiece becomes an anode and the cutting tool (in the case of ECG, a grinding wheel) becomes the cathode.
The Electrochemical Grinding (ECG) process removes material with low cutting force increasing wheel life and providing a burr free, stress free part with no recast or heat affected zone. The CS1-EA combines the best of the CS1-A Precision Abrasive and CS1-E Electrochemical Cutoff machines into one robust and compact design.
