1. Chemical polishing

The biggest advantage of chemical polishing compared with electrochemical polishing technology is that it does not need DC power supply and special fixture to polish complex shaped parts with high productivity. In terms of functionality, chemical polishing can not only obtain the physical and chemical cleanliness of the surface, but also remove the surface of the mechanical damage layer and stress layer, so as to get a mechanically clean surface after.

2. Electrolytic polishing

Electrolytic polishing is a special anodic process, in the anodic electrolytic grinding process, the surface simultaneously two contradictory processes, namely, the generation and dissolution of metal surface oxide film. Film formation and dissolution, in the polishing process will continue to generate, dissolve, so that the surface of the metal workpiece can be flattened to achieve a satisfactory smoothness and gloss to meet the surface polishing effect.

3. Fluid polishing

Fluid polishing is through the high-speed flow of liquid and polishing machine and the abrasive particles it carries to scour the surface of the metal workpiece, so as to achieve the purpose of surface polishing.

4. Magnetic polishing

Magnetic grinding polishing is the use of magnetic grinding in the magnetic field magnetic field under the action of the formation of abrasive material brush, grinding processing of the workpiece, the method of high processing efficiency, good quality, easy to control the processing conditions, good working conditions, the use of appropriate abrasive materials, surface roughness up to Ra0.1μm.

5. Ultrasonic polishing

On the basis of solution corrosion, electrolysis, the application of ultrasonic vibration stirring solution, separating the products of dissolution on the surface of the workpiece, so that the corrosion near the surface and electrolyte uniform ultrasonic cavitation in the liquid inhibits the corrosion process, which is conducive to surface glossing.

And we get a metal workpiece, can not be eager to polish, to be divided first to understand clearly the polishing needs and the effect to be achieved, and then according to the actual goal, to choose the appropriate metal workpiece polishing method.
