Electrochemical polishing principle
Electrochemical polishing, also known as electrolytic polishing. Electrolytic polishing is the workpiece to be cast as an anode, insoluble metal cathode, the two poles while immersed in the electrolytic cell, through the direct current generated by the selective anodic dissolution, so that the workpiece surface brightness increases, to achieve the mirror effect.
Mechanical polishing Mechanical polishing is by cutting, plastic deformation of the material surface to remove the polished convex and get a smooth surface of the polishing method, the general use of stone, wool wheel, sandpaper, etc., mainly to manual operation, special parts such as rotary Body surface, you can use turntables and other auxiliary tools, surface quality requirements can be super-precision polishing method. Ultra-precision polishing is the use of special abrasive, grinding fluid containing abrasive polishing press on the workpiece surface, for high-speed rotary motion. High Precision CNC Machining Aluminum Supplier The surface roughness Ra0.008m can be achieved by this technique, which is the highest among the various polishing methods. Optical lens mold often use this method.
