Precision parts processing technology was proposed in the 1960s. It improves the performance, quality, service life and reliability of mechanical and electrical products, and the cross section of the rod can be an important method. Precision processing means that the processing error is less than 0.1 M, the surface roughness is less than RA0.025ixm machining technology, also known as sub -micron processing. The level of precision parts is an important sign of the national manufacturing level.
In addition to the fluctuations of hydraulic and pneumatic sources in precision parts, the working environment has a great impact on the quality of processing. Therefore, the working environment is a necessary condition for ensuring the quality of processing. The working environment mainly has temperature, purification and vibration resistance.
The impact of ambient temperature changes on the accuracy of the machine tool is particularly significant, including temperature changes in thermostic factor caused by processing errors. The dust of the total processing error (4070)%will cause the surface of the workpiece The surface of the workpiece has been processed with stripes or fabric marks, and the surface smoothness has been significantly reduced.
