When processing precision mechanical parts, we must first work out the processing technology of mechanical parts to ensure that every link is normal. In the processing of precision mechanical parts, milling is used to produce and process a variety of metal materials and metal materials, and can carry out production and processing of plan views, inner and outer cylindrical surfaces and their cone surfaces.

The whole process of grinding can be done by carrying out micro-analysis and drilling of steel parts from the abrasive grains of mineral acid according to the grinding tool, including the comprehensive functions of complex physics and organic chemistry. Because the raw material of the grind tool is softer than the raw material of the steel to be grind, the abrasive grains in the abrasive are placed on the surface of the grind or fluctuate to form a multi-blade matrix. When the grind and steel parts are grinding and fitness exercises, they must work. Under pressure, micro-analysis drilling is carried out on the surface of steel parts.

When using chromium oxide, polyether or other abrasives, a very thin layer of air oxide film will be produced on the surface of the steel parts, which is very easy to be worn off. The air oxide film is constantly being ground during the whole grinding process. It is produced quickly and is continuously worn away by plants, which speeds up the whole process of grinding and reduces the roughness.
