Electrochemical Grinding Electrochemical grinding (ECG) utilizes a negatively charged abrasive grinding wheel, electrolyte solution, and a positively charged work- piece, as shown in Fig. 3.1. The process is, therefore, similar to ECM except that the cathode is a specially constructed grinding wheel instead of a cathodic shaped tool like the ...
