It is impossible to finish all the machining contents of all the surfaces in one process. <br>
The whole machining process of precision parts can be divided into the following stages: < br > the whole machining process of precision parts can be divided into the following stages
1. Rough machining stage. The main consideration is to cut off most of the machining allowance of each machining surface and process the fine datum, so as to improve the productivity as much as possible. <br>
2. Finishing stage. It is mainly used to reduce the surface roughness value or strengthen the machined surface. It is mainly used for the surface machining with high surface roughness requirements (RA ≤ 0.32 μ m). <br>
3. Semi finishing stage. It is required to achieve a certain machining accuracy, ensure the appropriate finishing allowance, and complete the secondary surface processing. <br>
4. Finishing stage. In this stage, large cutting speed, small feed rate and cutting depth are used to cut off the finishing allowance left by the previous process, so that the part surface can meet the technical requirements of the drawing. <br>
5. Ultra precision machining stage. The machining accuracy is 0.1-0.01 μ m, and the surface roughness Ra ≤ 0.001 μ M. The main processing methods are: precision cutting, precision mirror grinding, precision grinding and polishing. <br>
