The basic principle of grinding in the machining of precision mechanical parts
In the processing of precision mechanical parts, we must first develop the processing technology of mechanical parts to ensure that every link is normal. In the processing of precision mechanical parts, grinding is used to produce and process a variety of kinds of metal materials and metal materials, and can carry out the production and processing of the plan, internal and external cylindrical surface and its cone surface.
The whole process of grinding can be done by the trace analysis of the steel parts according to the grinding tool, including the comprehensive effect of complex physics and organic chemistry. Because the raw material of the grinding tool is softer than the raw material of the coated steel parts, the grinding particles in the abrasive agent are inserted into the surface layer of the grinding tool to form a multi-blade matrix. When the grinding tool and the steel parts exercise, the surface of the steel parts is microanalyzed and drilled under the necessary working pressure.
When using chromium oxide, polyether or other grinding agent, the surface of steel parts will produce a layer of extremely thin air oxide film. This layer of air oxide film is very easy to be worn away. In the whole process of grinding, the air oxide film is constantly produced rapidly, and continuously ground by plants, thus accelerating the whole process of grinding and reducing the roughness.
The passivated grinding particles squeeze the surface of the steel parts, which makes the raw materials deformed, and the peak and valley of the steel parts tend to be hot in the plastic deformation or cause cold hardening in the continuous deformation, and produce small cutting to rupture.
