During the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing intactness, and difficulty in removing chips are seriously affected, which seriously affects the quality, production cycle and processing cost of Precision parts. According to the theory of metal skills, metal cutting, non-standard equipment parts processing principles and other theories, the above-mentioned material processing difficulties are analyzed, and a set of effective stainless steel data drilling, reaming, and boring processing skills are explored. China's mechanical manufacturing operations are constrained by skills and talents, and it is difficult to compete with major European and American companies in terms of skill innovation and product development. However, with the influx of foreign capital and the intensification of work competitions, domestic machinery parts processing work has increased investment in independent development, and has achieved endless results, especially in the digital display skills and digital display hardware of the mechanical measuring instrument production company Gage commodities have been broken. For example, the 2m cnc gear measuring instrument that has been successfully developed in China has become a precision measuring instrument with strong international competition strength. In addition, by virtue of external forces, it also provided excellent assistance to domestic machining companies in terms of skills. Nowadays, most domestic non-standard equipment parts processing companies have introduced many foreign precision machining equipment brands. There is no shortage of equipment imported from Japan and Germany in this center. With the assistance of external forces, it also largely improves the accuracy and quality of the products processed from non-standard equipment parts.

  Non-standard equipment parts processing needs to obtain super-lubricated processing appearance and high processing accuracy. This requires the knife to have a high standard life. Whether the tool is worn or not, it will be based on whether the appearance quality of the processing reduces the tolerance. The standard life of diamond tools is very high, and tool wear is also very slow when cutting at high speed. Therefore, in ultra-precision cutting, the cutting speed is not restricted by the tool life, which is different from the general cutting rules.

  The cutting speed selected for non-standard equipment parts processing practice is often selected based on the dynamic characteristics of the ultra-precision machine tool used and the dynamic characteristics of the cutting system, that is, the rotation speed with the smallest vibration. At this speed, the surface roughness is the smallest and the processing quality is the highest. Obtaining high-quality non-standard mechanical processing appearance is the primary question for non-standard equipment parts processing. The use of good quality, especially good dynamic characteristics, low vibration, ultra-precision machine tools can use high cutting speeds and can process power.

  The selection of non-standard equipment parts processing parameters mainly includes the selection of the cutting tool viewpoint, the cutting speed and the cutting depth and feed speed. From the past experience, we know that when processing plastic data, if you choose a tool with a larger rake angle, you can effectively suppress the formation of the built-up edge. This is when the tool rake angle increases, the cutting force decreases, the cutting deformation is small, and the tool and chip The contact length becomes shorter, which reduces the foundation of built-up edge.
