Electrochemical grinding - Wikipedia

Electrochemical grinding - Wikipedia Currents involved The needed current is proportional to the desired rate of material removal, and the removal rate in mm/minute is proportional to the amps per square mm. Typical currents range from 0.1 amp per square mm to 5 amps per square mm. Thus, for a small plunge cut of a 1 by 1 mm tool with a slow ...

Applications of Electrochemical grinding. Electrochemical grinding is often used for hard materials where conventional machining is difficult and time-consuming, such as stainless steel and some exotic metals. For materials with hardness greater than 65 HRC, ECG can have a material removal rate 10 times that of conventional machining.

Electrochemical grinding is a combination of electrochemical machining and grinding processes. The major difference between ECM and ECG is that In ECG grinding wheel is used instead of a cutting tool. Electrochemical grinding is done when there is a need to remove the material from the surface of the workpiece.

In Electrochemical grinding, the metal bonded grinding wheel filled with a non-conductive abrasive. The grinding wheel act as a cathode and the workpiece is act as an anode. The electrolyte, which is usually sodium nitrate, sodium chloride, potassium nitrite, with a concentration of 0.150 to 0.300 kg/litre of water.

Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
