 During the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing appearance integrity, and difficulty in chip removal will appear, which seriously affect the quality, production cycle and processing cost of precision parts with such materials. According to the theories of metal skills, metal cutting and non-standard equipment parts processing, the difficulties in the above-mentioned material processing are analyzed, and a set of effective stainless steel drilling, reaming and boring processing skills are explored. China's machinery manufacturing industry is constrained by skills and talents, and it is difficult to compete with large companies in Europe and America in terms of skills innovation and commodity research and development. However, with the influx of foreign capital and the intensification of work competitions, domestic machinery parts processing has increased investment in independent development, and has achieved infinite results. In particular, the mechanical measuring instrument manufacturing company has completed a breakthrough in digital display skills and digital display hardware measuring tools. For example, the 2-meter CNC gear measuring instrument successfully developed in China has become a precision measuring instrument with great competition strength in the world. In addition, relying on external forces, it has also provided excellent assistance to domestic machining companies in terms of skills. First of all, most domestic non-standard equipment parts processing companies have introduced many large foreign brands of precision machining equipment. There is no shortage of equipment imported from Japan and Germany. With the help of external forces, the accuracy and quality of goods processed by non-standard equipment parts have been greatly improved.

 The machining of non-standard equipment parts requires super lubricated machining appearance and high machining accuracy, which requires that the tool has a high standard life. Whether the tool is worn or not will be based on whether the machining appearance quality is reduced. The standard life of diamond tools is very high, and the tool wear is very slow in high-speed cutting. 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 in the machining practice of non-standard equipment parts is often selected according to the dynamic characteristics of the ultra precision machine tool and the cutting system, that is, the speed with the minimum vibration. Since the surface roughness is the smallest and the machining quality is the highest at this rotational speed. Obtaining high-quality non-standard machining appearance is the primary question of non-standard equipment parts processing. Ultra precision machine tools with good quality, especially good dynamic characteristics and low vibration can be used for high cutting speed and processing power.

 The selection of machining parameters of non-standard equipment parts mainly includes the selection of cutting tool viewpoint, cutting speed, cutting depth and feed speed. From the past experience, we know that when processing plastic data, if a tool with a larger rake angle is selected, the formation of chip build-up can be effectively suppressed. This is the basis for reducing the formation of chip build-up when the rake angle of the tool increases, the cutting force decreases, the cutting deformation is small, and the contact length between the tool and the chip becomes shorter.
