During the design process of precision mechanical component processing, it is not only necessary to meet its usage requirements, that is, to have the required work ability, but also to meet production requirements during the operation process. Precision mechanical component processing is easy to process and has low processing costs during the design process. Such parts are to some extent referred to as having good processability.
Basic requirements for the processing technology of precision mechanical components:
1. In the process of selecting raw materials, it is necessary to use the reasonable raw material preparation methods in mechanical manufacturing. During the operation, methods such as profiles, casting, forging, welding, and stamping are directly used. The selection of raw materials during use is related to specific production technology conditions, and generally depends on the production batch, talent performance, and processing possibility.
2.The structure of precision mechanical parts processing is very simple in the design process. When operating, simple surfaces and combinations are mainly used, and to a certain extent, the number of processed surfaces and processing area should be minimized as much as possible.
3. The cost of precision machining parts with appropriate manufacturing precision and surface roughness will increase with the improvement of their precision. When operating with high precision, this increase is extremely significant. Therefore, without sufficient basis, high precision should not be pursued. Similarly, the surface roughness of the parts should also be appropriately specified according to the actual needs of the mating surface.
4. When precision mechanical components are processed to a certain extent, they must be designed with good processability. In the process of design, it is necessary to combine with process technicians and be good at learning from them. In addition, some basic knowledge about processability is also provided in metal technology courses and manuals.
The surface roughness of precision mechanical parts processing can effectively reflect the error of the micro geometric shape of the part surface to a certain extent, which is a very important technical indicator. When used, this is the main basis for checking the surface quality of the part.
