Electrochemical grinding (ECG) is a hybrid machining process in which material removal happens by joint action of electrochemical machining (ECM) and mechanical grinding. About 90–95% material is detached from machined components through anodic dissolution by chemical reaction, and remaining 5–10% material is detached through abrasion ...

2.Electrochemical Grinding (ECG) 1.In ECG, the material removal is achieved by combined action of abrasive and electrochemical process energy. The resulting surface has high surface integrity, is burr free, and has negligible distortion. 2.The abrasive particles of the grinding wheel make a contact with the workpiece and the gap between the

difficult to process [4.5]. As a result, the application of tungsten and its alloys in a wider field is restricted. Electrochemical grinding is a composite processing method, which combines mechanical process with electrochemical effect [6]. Because of the electrochemical action, ECG can be used to process brittle materials with high hardness.

The results showed that the electrochemical characteristics could be highly predictive for the performance of ECG in different electrolytes. Besides, compared with CG, although the surface roughness after ECG increased, the grinding force was greatly reduced, and the material removal rate (MRR) was improved under recommended processing parameters.
