1. Mechanical polishing method: The abrasive material and the pipe surface are ground through mechanical force to achieve the purpose of removing surface defects. Commonly used grinding tools include grinding wheels, abrasive belts, grinding cloths, etc. The advantages of mechanical polishing are high processing efficiency, low cost, and suitable for mass production. The disadvantage is that the surface is rough and prone to scratches and residues.
2. Chemical polishing method: Surface defects are repaired through chemical reactions to improve surface finish. Commonly used chemical polishing agents include nitric acid, hydrofluoric acid, phosphoric acid, etc. The advantage of the chemical polishing method is that it has good surface quality and can remove minor defects and burrs. However, the disadvantage is that it is difficult to operate, requires strict control of process parameters, and the waste liquid and waste gas generated pollute the environment to a certain extent.
3. Electrochemical polishing: Its advantages are long-lasting mirror gloss, stable process, less pollution, low cost, and good corrosion resistance. Its disadvantages are high pollution prevention, large one-time investment in processing equipment, complex parts requiring tooling and auxiliary electrodes, and mass production also requires cooling facilities. It is suitable for mass production and is mainly used in high-end products, export products, and products with tolerances. Its processing technology is stable and the operation is simple.
