During the processing of non-standard equipment parts, there will be common problems such as accelerated tool wear, poor processing appearance integrity, and difficulty in chip removal, which seriously affect the quality, production cycle, and processing cost of precision parts with such data. Based on theories such as metal skills, metal cutting, and non-standard equipment parts processing principles, this paper analyzes the difficulties in material processing mentioned above, and explores a set of effective stainless steel data drilling, reaming, and boring processing skills. The mechanical manufacturing industry in China is constrained by skills and talent, making it difficult to compete with major companies in Europe and America in terms of skill innovation and product development. However, with the influx of foreign capital and the intensification of job competitions, domestic mechanical parts processing work has increased investment in independent development, and has achieved infinite results, especially in the field of digital display skills and digital hardware measuring tool products, where mechanical measuring tool production companies have achieved breakthroughs. The successful development of the 2-meter CNC gear measuring instrument in China has become a highly competitive precision measuring instrument internationally. Other external forces have also provided excellent assistance to domestic mechanical processing companies in terms of skills. Currently, most non-standard equipment parts processing companies in China have introduced many large foreign brands of precision mechanical processing equipment. This center has equipment imported from Japan and Germany. With the assistance of external forces, the accuracy and quality of products processed from non-standard equipment parts have also been greatly improved.
The processing of non-standard equipment parts requires superlubricity processing appearance and high processing accuracy, which requires that the tool has a high standard life. Whether the tool is worn or not will be based on whether the processing appearance quality reduces the out of tolerance. The standard life of diamond tools is very high, and tool wear is also very slow in high-speed cutting. Therefore, during ultra precision cutting, the cutting speed is not limited by the tool life, which is different from general cutting rules.
The selection of cutting speed for non-standard equipment parts processing internship is often based on the dynamic characteristics of the ultra precision machine tool used and the dynamic characteristics of the cutting system, that is, selecting the speed with the lowest vibration. Due to the minimum surface roughness and highest machining quality at this speed. Obtaining high-quality non-standard machining surfaces is the primary issue in the processing of non-standard equipment parts. Ultra precision machine tools with good quality, especially good dynamic characteristics and low vibration, can use high cutting speeds and can travel processing power.
The selection of processing parameters for non-standard equipment parts mainly includes the selection of cutting tool viewpoint, cutting speed, cutting depth and feed speed, etc. From past experience, we know that when processing plastic materials, selecting a tool with a larger rake angle can effectively control the formation of chip deposits. This is because 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, reducing the basis for the formation of chip deposits.
