The 5 stages of precision component machining

Precision parts processing is generally aimed at the production of precision mechanical equipment components, which requires very high precision. Therefore, in addition to understanding the specific material requirements and common techniques for precision mechanical parts processing, we should also understand the steps involved in the processing of precision mechanical parts. Below, Santongde Metal Products Co., Ltd. will share with you the five stages of precision mechanical parts processing.

1. Rough machining

The main consideration is to improve productivity. Most of the machining allowance on each processing surface has been removed, and a precision benchmark has been machined.

2. Semi precision machining

The main purpose is to remove defects that may occur after rough machining, while completing the machining of secondary surfaces. It is necessary to achieve a certain level of machining accuracy in order to prepare for the precision machining stage and ensure appropriate precision machining allowance.

3. Precision machining

In the precision machining stage, large cutting speeds, small feed rates, and cutting depths are mainly used to remove 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 used for surface machining with high surface roughness requirements.

5. Ultra precision machining

The main processing methods used are precision cutting, mirror surface grinding, precision grinding, and polishing to achieve a machining accuracy of 0.1-0.01 μ m and a surface roughness value ra ≤ 0.001 μ m.

Summary:

The five stages of precision parts machining are a gradual process from coarse to fine, and through these five stages of machining, the accuracy of mechanical components can meet the requirements of customers.
