This article provides a discussion on a working principle, the operations, characteristics, capabilities, and applications of electrochemical grinding (ECG). The basic elements of the ECG machine tool are also presented.

This article describes the various characteristics of electrochemical grinding (ECG). It discusses grinding methods that can be performed with ECG components, namely, the electrolyte delivery and circulating system, the electrolyte, the DC power supply, grinding wheel, and the workpiece. Grinding, surface grinding, internal grinding, form grinding, and cylindrical grinding are discussed. The article also lists the advantages, disadvantages, and applications of ECG.

Electrochemical discharge grinding (ECDG) is a combination of electrochemical grinding (ECG) and electrical discharge grinding (EDG), with some modification of each. This article commences with a schematic illustration of a setup for ECDG using a solid bonded graphite wheel. It describes the process characteristics of ECDG in terms of current density, wheel speed, wear ratio, accuracy and finish, wheel maintenance, and profile grinding. The article concludes with a comparison of ECDG with EDG and ECG.
