The electrochemical grinding (ECG) process offers a number of advantages over conventional grinding, such as low induced stresses, large depths of cut, increased wheel life and the ability to machine delicate workpieces. However, one disadvantage is the difficulty of controlling the dimensional accuracy of the workpiece.
Electrochemical grinding can increase grinding parameters, especially radial grinding stock (grinding depth). The productivity is 3-5 times higher than that of general grinding according to time per piece. (2) Good processing quality. In electrochemical grinding, the grinding wheel is mainly to remove the oxide film on the coating surface.

Grinding Services Overview. The machining process known as grinding or abrasive cutting uses a grinding wheel with an abrasive surface to cut or grind away unwanted material, creating a smooth finish. MW offers a few different grinding services including CNC grinding, electrochemical grinding (ECG), and precision sharpening.
ECG combines abrasive grinding with electrochemical machining to provide stress-free, low force, and burr-free cuts. Used extensively for medical and aerospace applications to cut high-temperature alloys, stainless-steels, and materials that are difficult to machine. Typical applications include needles, fasteners, and tube cutoff.
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process.
