Mechanical parts processing industry is the pillar of the national economy, with a very promising future. When processing precision mechanical parts, processing plants have many requirements and regulations for the processing process to ensure the qualification rate of the factory parts. So what are the factors that affect the processing of precision parts? Let's take a look below!
Precision parts machining technology was proposed in the 1960s, it is to improve the performance, quality, service life and reliability of electromechanical products, as well as the cross-section of the bar can be an important method, precision machining refers to machining errors less than 0.1m, surface roughness less than RA0.025IXM processing technology, also known as sub-micron processing, precision parts machining level is the level of national manufacturing Important symbol.
In addition to the fluctuations of hydraulic and pneumatic sources in precision parts machining, the working environment has a great impact on the quality of processing, so the working environment is necessary to ensure the quality of processing, the working environment mainly temperature, purification and anti-vibration requirements.
Environmental temperature changes on the machine tool accuracy is particularly significant, including temperature changes due to processing errors caused by thermal factors, the total machining error (4070) % of dust can lead to surface scratches on the workpiece and affect the surface quality process, such as vibration occurs, the surface of the workpiece has been processed streaks or fabric traces, the surface finish is significantly reduced.
With the high precision of parts processing requirements, the requirements of the processing environment more and more stringent, only from the precision parts processing on the impact of gas pressure fluctuations, ambient temperature changes, external and self-vibration three aspects of the analysis, the impact of precision parts processing factors are many, in order to improve the accuracy of ultra-precision machining, not only to understand the impact of factors, but also must master the solution.
