In the processing of precision machinery parts, the first thing to develop the processing technology of mechanical parts, to ensure that each link is normal. Grinding is used in the machining of precision machinery parts. The entire grinding process can be completed by micro-analysis drilling of the steel parts with inorganic acid abrasive particles based on the grinding tool, and involves a combination of complex physics and organic chemistry. Because the raw material of the abrasive is softer than the raw material of the steel being ground, the abrasive particles in the abrasive are placed on the surface of the abrasive or shaken to form a multi-edge matrix. The steel surface is drilled for microscopic analysis under the necessary working pressure.
