Polishing is a finishing process performed by a polishing wheel coated with fine powder in a high-speed motion state. The main purpose is to improve the surface roughness of the part.

Plane polishing machine refers to a machine that performs ultra-precision processing of flat workpieces, removes scratches, spots, and collapses on the surface of the workpiece, and makes the surface of the workpiece bright and smooth, with a mirror effect or even a precise roughness value.

At present, the transition of polishing machine to high-end has gradually revealed its strong development momentum, and the automation and intelligence of equipment will be greatly improved. Polishing machines play a key role in the quality, appearance, sales, circulation, use and cost of hardware. At home and abroad, especially European and American countries, more and more attention is paid to the research and development of hardware polishing machines. With the continuous expansion of the domestic polishing industry, traditional polishing equipment can no longer meet the needs of the rapid development of the industry. In addition, the introduction of a compulsory certification system in my country has greatly improved the various requirements of domestic hardware production, and has also stimulated the continuous increase in the demand for automatic and intelligent high-end polishing machinery from polishing enterprises in various regions.

Polishing is generally divided into rough polishing and fine polishing: the purpose of rough polishing is to remove the polished damage layer. This stage should have the largest polishing rate. The surface damage caused by rough polishing is a secondary consideration, but it should be as small as possible; secondly It is fine polishing (or final polishing). Its purpose is to remove surface damage caused by rough polishing and minimize polishing damage.

After fine polishing, the polished surface is bright as a mirror, and no scratches can be seen under the bright field of the microscope, but the wear marks can still be seen under the phase contrast illumination. The polishing quality of the polishing machine seriously affects the structure of the sample, which has gradually attracted the attention of relevant experts. A lot of research work has been done on the performance of polishing machines at home and abroad, and many new models and new generation polishing equipment have been developed. The original manual operation is developing into a variety of semi-automatic and fully automatic polishing machines.
