Precision mechanical parts processing
Generally, processing and production are carried out for the components of precision mechanical equipment, which requires a very high level of accuracy. Therefore, in addition to understanding the specific requirements for materials and commonly used techniques in precision mechanical component processing, we should also understand the processing steps of precision mechanical component processing. Below, we will share with you the five stages of precision mechanical component processing
1. Rough machining
The main consideration is to improve productivity. Most of the machining allowances on each machining surface are cut off and precision benchmarks are produced
2. Semi precision machining
The main task is to remove defects that may occur after rough machining, while completing the processing of secondary surfaces. It is necessary to achieve a certain machining accuracy in order to prepare for the finishing stage and ensure appropriate finishing allowance
3. Fine processing
In the precision machining stage, high cutting speed, small feed rate, and cutting depth are mainly used to cut the machining allowance left by semi precision machining, so that the surface of precision mechanical components meets the technical requirements of the drawings
4. Finishing processing
Mainly used to reduce surface roughness or strengthen machined surfaces, mainly for surface processing with high surface roughness requirements
5. Ultra precision machining
The main processing methods used are precision cutting, precision mirror grinding, precision grinding, and polishing to achieve a machining accuracy of 0.1-0.01&mu for the workpiece; m. Surface roughness value ra≤ 0.001μ m。
