At present, precision hardware processing components. Hardware precision parts processing manufacturers have already achieved precision μ M level, it not only requires high-precision processing machinery and equipment, CNC blades, high-precision testing instruments, and highly skilled employees, but also a good processing natural environment is a key factor to ensure the accuracy of precision hardware processing.

In the whole process of precision machinery and equipment processing, the processing technology system software of precision hardware Machine element is endangered by the drilling heat, friction heat and other internal pyrogens, while heat exchange with environmental factors is carried out.

Precision hardware processing is unlikely to involve all surface processing within a single process flow. The entire process of precision hardware processing can be divided into the following stages:

1. Rough machining stage. Remove the vast majority of machining allowances from each machining surface and produce precision standards, with the key consideration of improving production efficiency as much as possible on the ground.

2. Semi precision machining stage. After removing the defects that may be caused by rough machining, prepare for surface finishing and ensure a certain machining accuracy to ensure moderate finishing allowance. At the same time, carry out the processing of primary and secondary surfaces.

3. Precision processing stage. At this stage, a large cutting amount is selected, precision hardware components are processed at a low cutting speed and deep drilling depth, and the remaining finishing allowance from the previous process is removed to ensure that the surface of the parts meets the technical standards of the sample drawing.

4. Finishing stage. The key is to reduce the surface roughness value or strengthen the machined surface, and the key is to specify a high surface roughness (ra ≤ 0.32 μ m) Surface processing.

5. Ultra high precision machining stage. Processing accuracy between 0.1-0.01 μ m. Surface roughness value ra ≤ 0.001 μ The processing stage of m. The key processing methods include high-precision drilling, precision mirror glass cutting, high-precision grinding, and polishing.
