The equipment for processing precision mechanical parts mainly includes CNC lathes, milling machines, planers, grinders, CNC machining centers, etc. When processing precision mechanical parts, we need to know the specific requirements of precision mechanical parts processing for materials and precision mechanical parts. It is impossible to complete all the processing contents of all surfaces in one process with precision mechanical parts processing. The entire processing process of precision parts processing can be divided into the following stages:

(1) Roughing stage. Most of the machining allowance of each machined surface is removed, and the fine reference is machined, and the main consideration is to increase the productivity as much as possible.

(2) Semi-finishing stage. To remove the defects that may occur after rough machining, to prepare for the finishing of the surface, it is required to achieve a certain machining accuracy, ensure an appropriate finishing allowance, and complete the machining of the secondary surface at the same time.

(3) Finishing stage. At this stage, high cutting speed, small feed and cutting depth are used to remove the finishing allowance left by the previous process, so that the surface of the part can meet the technical requirements of the pattern.

(4) Finishing stage. It is mainly used to reduce the surface roughness value or strengthen the machined surface, and it is mainly used for surface machining with high surface roughness requirements (ra≤0.32μm).

(5) Ultra-precision machining stage. The processing accuracy is 0.1-0.01μm, and the surface roughness value ra≤0.001μm is in the processing stage. The main processing methods are: precision cutting, fine mirror grinding, precision grinding and polishing.

The processing of precision mechanical parts is very important for the selection of cutting tools and cutting machine tools. These hardware devices affect the processing efficiency of precision mechanical parts to a certain extent. If you want to improve the processing efficiency of mechanical parts, you have to choose Large-scale machining plants with high technical personnel can ensure both the quality of the workpiece and the processing efficiency of the workpiece to a greater extent.
