Basic requirements for processing technology of precision mechanical parts

In the process of design, the processing of precision mechanical parts should not only meet the use requirements, that is, have the required ability to work, but also meet the production requirements in the process of operation. In the process of design, the processing of precision mechanical parts is easy to process and the processing cost is very low. To a certain extent, such parts will be called having good processing ability Artistry. Basic requirements for processing technology of precision mechanical parts

one In the process of blank selection, it is necessary to adopt the blank preparation method in mechanical manufacturing. In operation, it will directly use its profile, casting, forging, welding, stamping and other methods. In use, the blank selection is related to the specific production technology 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 design. The simplest surface and combination are mainly used in the operation. To a certain extent, the minimum number of machined surfaces and the minimum machining area should be used as far as possible.

3. The cost of machining precision mechanical parts with proper manufacturing accuracy and surface roughness will increase with the improvement of its accuracy. In the case of high accuracy, the increase is extremely significant. Therefore, when there is no sufficient basis, high accuracy should not be pursued. In the same way, the surface roughness of parts should also be properly specified according to the actual needs of the matching surface.

4. When precision mechanical parts are processed to a certain extent, the parts with good processability are designed. In the process of design, it is necessary to combine with the technical staff and be good at learning from them. In addition, some basic knowledge about processability is also provided in the metal technology course and manual for reference. To a certain extent, the surface roughness of precision mechanical parts can effectively reflect the error of the micro geometry of the part surface, which is a very important technical index. When it is used, it is the main basis for testing the surface quality of parts.
