Precision parts machining process

It is impossible to complete all the processing contents of all surfaces in one process for precision parts processing. The entire processing process of precision parts processing can be divided into the following stages:

(1) Rough processing stage. Most of the processing allowances of each processing surface are removed, and the precision datum is processed, mainly considering to maximize productivity.

(2) Semi-finishing stage. Defects that may occur after rough processing are removed to prepare for surface finishing. It is required to achieve a certain processing accuracy, ensure appropriate finishing allowances, and complete the processing of secondary surfaces at the same time.

(3) Finishing stage. In this stage, a high cutting speed, a small feed rate and a cutting depth are used to remove the finishing allowances left by the previous process so that the surface of the part meets the technical requirements of the drawing.

(4) Finishing stage. It is mainly used to reduce the surface roughness value or strengthen the processing surface. It is mainly used for surface processing with very high surface roughness requirements (ra≤0.32μm).

(5) Ultra-precision processing stage. The processing stage with a processing accuracy of 0.1-0.01μm and a surface roughness value of ra≤0.001μm. The main processing methods are: precision cutting, precision mirror grinding, precision grinding and polishing, etc.
