Hi, Welcome to factory !
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...
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
Electrochemical grinding ECG is a variation of electrochemical machining ECM, in which material is removed from the workpiece by simultaneous electrochemical reaction and mechanically abrasive action. It offers a number of advantages over conventional grinding, such as low induced stress, large depths of cut, and increased wheel life.
Electrochemical grinding. The main feature of electrochemical grinding ECG is the use of a grinding wheel in which an insulating abrasive, such as diamond particles, is set in a conducting material. This wheel becomes the cathode tool.
May 14, 2015 Molecular decomposition process is an electrochemical grinding process that has been refined to enable The removal of increased amount of material while maintaining workpiece temperature to within 1 F. Reduced mechanical force to the workpiece. From roughing operations surface finishes achieved measure at 6 to 8 Ra in.
Electrolytic processing uses a low-voltage DC power supply 6 24 volts, a large operating current. In order to maintain a continuous and smooth supply of electrolyte to the electrolysis zone with sufficient flow rate and suitable temperature , the processing is generally carried out in a sealing device. Conductive grinding
Apr 01, 2000 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 ECG is one of the examples of ECM which is a combination of conventional grinding and ECM processes. ECG has an up to 595 grinding ratio of conventional grinding to ECM. The price of an ECG machine in the market reaches 53 million rupiahs.
