Basic principles of grinding in the processing of precision mechanical parts

When processing precision mechanical parts, we must first formulate the processing technology of mechanical parts to ensure that each joint is flat. In the processing of precision machinery parts, grinding is used to produce and process all kinds of metal materials and metal materials, and it is possible to carry out production and processing of plan views, inner and outer cylindrical surfaces and their conical surfaces.

The whole process of grinding can be done by the abrasive grain of mineral acid and the grinding tool. Micro-analytical drilling of steel parts involves a combination of complex physics and organic chemistry. Since the raw material of the grinding tool is softer than the raw material of the steel to be ground, the abrasive particles in the abrasive are placed in the upper layer of the grinding tool or fluctuate to form a multi-blade matrix. Be sure to carry out micro-analytical drilling on the upper layer of the steel under working pressure.

When using chromium oxide, polyether or other abrasives, the upper layer of the steel will produce a very thin atmosphere oxide film, which is very easy to be ground off. In the middle of the process, the oxide film in the atmosphere is produced rapidly, and it is ground by the plants one after another, which accelerates the whole grinding process and reduces the roughness.

The passivated abrasive grains extrude the upper layer of the steel part, causing the raw materials to be processed to cause deformation, and the peaks and valleys of the upper layer of the steel part tend to be ironed during plastic deformation or lead to continuous deformation. Cold-worked and tough, resulting in micro-cutting to chipping.
