Five stages of precision parts processing

Precision parts processing is the precision machining of precision parts for precision equipment, which requires high precision. This also leads us to not only understand the specific requirements of parts processing on materials, and the common skills of processing parts, but also should understand the precision What are the stages of the process of processing precision parts, the following is the Asian and American precision dispatcher to share with you the five stages of precision mechanical parts processing.

1. Roughing

Mainly to increase productivity. The machining allowance of the machined surface is cut off, and the precision reference is processed.

2. Semi-finishing

It is mainly to remove the defects that may occur after rough machining, and at the same time complete the processing of the secondary surface. A certain machining accuracy must be achieved in order to prepare for the finishing stage to ensure an appropriate finishing allowance.

3. Finishing

The parts processed by precision parts mainly use large cutting speed, small feed rate and cutting depth to remove the machining allowance left by semi-finishing during the finishing stage, so that the surface of precision mechanical parts meets the technical requirements of the drawings.

4. Finishing

It is mainly used to reduce the surface roughness or strengthen the processed surface, and is mainly used for surface processing with high surface roughness requirements.

5. Ultra-precision machining

Mainly using precision cutting, precision mirror grinding, precision grinding and polishing and other processing methods to make the processing accuracy of the workpiece 0.1-0.01μm, surface roughness value ra≤0.001μm.

to sum up

The five stages of precision parts processing are from coarse to fine and gradually refined. After these five stages of processing, the accuracy of mechanical parts can meet the requirements of customers.
