Factors affecting precision parts machining
The mechanical parts processing industry is a pillar industry of the national economy with very promising prospects. When processing precision mechanical parts, processing factories have many requirements and regulations for the processing technology to ensure the qualification rate of the parts leaving the factory. Do you know what factors affect precision parts machining? Let's take a look together below!
Precision machining technology for mechanical and electrical products was proposed in the 1960s. It is an important method to improve the performance, quality, service life, and reliability of mechanical and electrical products, as well as the cross-sectional area of bar materials. Precision machining refers to machining technology with a machining error of less than 0.1m and a surface roughness of less than RA0.025IXM, also known as sub micron machining. The level of precision machining is an important indicator of the manufacturing industry's level.
In addition to the fluctuations of hydraulic and pneumatic sources in precision parts machining, the working environment has a significant impact on machining quality. Therefore, the working environment is a necessary condition to ensure machining quality. The working environment mainly includes temperature, purification, and anti vibration requirements. The impact of environmental temperature changes on machine tool accuracy is particularly significant, including temperature changes caused by thermal factors due to machining errors. Dust with a total machining error of (40 70)% can cause scratches on the surface of the workpiece and affect surface quality. During the process, if vibration occurs, stripes or fabric marks have already been machined on the surface of the workpiece, and the surface smoothness is significantly reduced.
With the increasing demand for high precision in parts processing, the requirements for the processing environment are becoming more and more stringent. From the analysis of the impact of precision parts processing on gas pressure fluctuations, environmental temperature changes, and external and natural vibrations, there are many factors that affect precision parts processing. In order to improve the accuracy of ultra precision processing, it is not only necessary to understand the influence of factors, but also to master solutions.
