What are the factors that affect the machining of precision parts?

The mechanical parts processing industry is the pillar industry of the national economy and has very considerable prospects. When processing precision mechanical parts, the parts processing factory will have many requirements and regulations on the processing technology to ensure the pass rate of the factory parts. So what are the factors that affect the processing of precision parts? Let's take a look together!

Precision parts machining technology was proposed in the 1960s, it is an important method to improve the performance, quality, service life and reliability of mechanical and electrical products, and the section of the bar can be an important method, precision machining refers to the machining error less than 0.1 m, the surface roughness is less than RA0.025IXM processing technology, also known as sub-micron processing, precision parts processing level is an important symbol of the national manufacturing level.

In addition to the fluctuation of hydraulic and pneumatic sources in precision parts processing, the working environment has a great influence on the processing quality, so the working environment is a necessary condition to ensure the processing quality, and the working environment mainly has the requirements of temperature, purification and anti-vibration.

The influence of ambient temperature changes on the accuracy of machine tools is particularly significant, including temperature changes due to thermal factors caused by machining errors. Dust with a total machining error of (4070)% will cause scratches on the surface of the workpiece and affect the surface quality. During the process, such as vibration , the surface of the workpiece has been processed with stripes or fabric traces, and the surface finish is significantly reduced.

With the high precision required for parts processing, the requirements for the processing environment are becoming more and more stringent. Only from the analysis of the influence of precision parts processing on gas pressure fluctuations, ambient temperature changes, external and natural vibration, the analysis of precision parts processing factors There are many influences. In order to improve the accuracy of ultra-precision machining, it is necessary not only to understand the influence of factors, but also to master solutions.
