When we are processing the product due to the flaws of the raw material, we usually use polishing to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It’s widely uses in machinery and tool manufacturing, precision engineering and related equipment, automobile and automobile manufacturing, aviation and aerospace engineering, construction and interior decoration industries. So do you know what kinds of polishing methods are there? Let’s follow me to learn about 4 common polishing methods.
1. Mechanical mirror polishing
It will be treated with a polishing wheel coated with a polished surface, which can reduce the surface of the shell, make the surface of the processed surface effect, and brighten the surface to change the surface effect, effectively repairing the surface scratches and scratches on the surface scratched.
2. Electropolishing:
Electrolytic polishing uses the polished parts as the anode and the insoluble metal as the cathode. The two electrodes are immersed in the electrolytic cell at the same time, and the DC ionization reaction produces selective anode dissolution to achieve a smooth and bright surface.
3. Chemical polishing
Chemical polishing can be used as a pre-treatment for decorative electroplating, or as a pre-treatment for chemical film formation such as phosphating and bluing. If dipped in anti-rust and passivation aqueous solution before painting, it can be used as the coating on the surface of the workpiece.
4. Ultrasonic polishing
Ultrasonic polishing is a processing method that uses the tool section to perform ultrasonic vibration and polishes brittle and hard materials through abrasive suspension. Put the workpiece into the abrasive suspension and put it together in the ultrasonic field, relying on the ultrasonic oscillation effect. The abrasive is ground and polished on the surface of the workpiece.
