When processing precision mechanical parts, we must first formulate 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 metal materials and metal materials, and can produce and process the plan, inner and outer cylindrical surfaces and their conical surfaces.
What can be done in the whole grinding process is that the grinding particles of mineral acid carry out micro analysis and drilling of steel parts according to the grinding tool, including the comprehensive effects of complex physics and organic chemistry. Because the raw material of the grinding tool is softer than the raw material of the steel part to be studied, the abrasive grains in the abrasive are placed in the surface of the grinding tool or fluctuate to form a multi-edge matrix. When the grinding tool and the steel part are grinding and fitness exercises, the micro analysis drilling is carried out on the surface of the steel part under the necessary working pressure.
When chromium oxide, polyether or other abrasives are selected, a very thin layer of air oxide film will be produced on the surface of steel parts. This layer of air oxide film is very easy to be ground off. During the whole grinding process, the air oxide film is constantly and rapidly produced, and then continuously ground off by plants, thus speeding up the whole grinding process and reducing the roughness.
The passivated abrasive grains carry out extrusion molding on the surface of the steel parts, causing deformation of the raw materials to be produced and processed. The peaks and valleys of the surface of the steel parts tend to be flattened in plastic deformation or cause cold work hardening in continuous deformation, and then fracture to produce micro cutting.
