In the process of designing, the processing of precision mechanical parts must not only meet its use requirements, that is, have the ability to work required, but also meet the production requirements during the process of operation. The process is easy to process and the processing cost is very low, such parts will be called with good manufacturability to a certain extent.
Basic requirements for processing technology of precision machinery parts
1. In the process of selecting the blank, it is necessary to adopt the blank preparation method in the reasonable amount of mechanical manufacturing, and directly use its profile, casting, forging, welding and stamping methods during operation. The selection of the blank is related to the specific production technical conditions, and generally depends on the production batch, ability, performance, and processing possibility.
2. The structure of precision mechanical parts processing is very simple in the process of designing. In the operation, simple surfaces and combinations are mainly used. To a certain extent, the processed surface should be used as much as possible. The number is small and the processing area is small.
3. Precise mechanical parts processing regulations require proper manufacturing accuracy and surface roughness. The cost will increase with the improvement of its accuracy. In the case of high accuracy during operation, such The increase in is extremely significant, therefore, high accuracy should not be pursued when there is no sufficient basis. In the same way, the surface roughness of the parts should also be appropriately specified according to the actual needs of the mating surface.
4. When the precision mechanical parts are processed to a certain extent, they design parts with good manufacturability. In the process of designing, they must be combined with process and technical staff and be good at learning from them. In addition, in metal technology The courses and manuals also provide some basic knowledge about craftsmanship for reference.
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. It is a very important technical index. This is the main basis for testing the surface quality of the parts during use. .
