Precision mechanical parts processing

Generally, it is for the

processing and production of parts of precision mechanical equipment, which requires a very high precision, so in addition to understanding the specific requirements of precision mechanical parts processing for materials and the common skills of precision mechanical parts processing, we should also understand what are the steps in the processing process of precision mechanical parts processing, and I will share with you the five stages of precision mechanical parts processing.

1. Rough machining

The main consideration is to increase productivity. Most of the machining allowance of each machining surface is removed, and the precision standard is machined.

2. Semi-finishing

The main purpose is to remove the defects that may occur after roughing, and at the same time complete the machining of secondary surfaces. A certain machining accuracy must be achieved in order to prepare for the finishing stage and to ensure an appropriate finishing allowance.

3. Finishing

In the finishing stage, large cutting speed, small feed and cutting depth are mainly used to cut off the machining allowance left by semi-finishing, so that the surface of precision mechanical parts meets the technical requirements of the drawings.

4. Finishing processing

It is mainly used to reduce surface roughness

or strengthen the machined surface, and is mainly used for surface processing with high surface roughness requirements.

5. Ultra-precision machining

It is mainly used to make the machining accuracy of the workpiece 0.1-0.01μm, and the surface roughness value Ra≤0.001μm is 0.001μm.
