Precision mechanical parts processing is generally aimed at the parts of precision mechanical equipment, which requires very high precision. Therefore, in addition to understanding the specific requirements for materials and common skills of precision mechanical parts processing, we should also know what steps are involved in the processing of precision mechanical parts, Let's share with you the five stages of precision machinery parts processing.
1. Rough machining
The main consideration is to improve productivity. Most of the machining allowance of each machining surface is removed, and the precision datum is machined.
2. Semi finishing
It mainly refers to the removal of defects that may occur after rough machining, and the processing of secondary surfaces. A certain machining accuracy must be achieved to prepare for the finishing stage and ensure proper finishing allowance.
3. Finishing
In the finishing stage, large cutting speed, small feed rate and cutting depth are mainly used to cut off the machining allowance left by semi finishing to make the surface of precision mechanical parts meet the technical requirements of drawings.
4. Finishing
It is mainly used to reduce the surface roughness or strengthen the machined surface. It is mainly used for surface processing with high requirements for surface roughness.
5. Ultra precision machining
It mainly uses precision cutting, precision mirror grinding, precision grinding, polishing and other processing methods to make the machining accuracy of the workpiece within 0.1-0.01 μ m. Surface roughness value ra ≤ 0.001 μ m。
summary
The five stages of precision mechanical parts processing are from coarse to fine and gradually refined. After these five stages of processing, the precision of mechanical parts can meet the requirements of customers. Weituo Precision Machinery focuses on the processing and manufacturing of precision machinery parts. It can process according to the drawings and materials required by customers to produce precision machinery parts that customers are satisfied with.
