During the processing of non-standard equipment parts, there are common issues such as accelerated tool wear, poor surface integrity, and difficulty in chip removal, which seriously affect the quality, production cycle, and processing cost of precision parts processing. Based on theories such as metal skills, metal cutting, and non-standard equipment parts processing principles, this paper analyzes the difficulties in material processing and explores a set of effective stainless steel data drilling, hinge, and boring processing skills. China's mechanical manufacturing industry is constrained by skills and talents, making it difficult to compete with large companies in Europe and America in terms of skill innovation and product research and development. But with the influx of foreign capital and the intensification of work 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. The 2-meter CNC gear measuring instrument, which has been successfully developed domestically, has become a highly competitive precision measuring instrument internationally. By relying on external forces, it has 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 machining of non-standard equipment parts requires a super lubricated machining surface and high machining accuracy, which requires the tool to have a high standard life. Whether the tool is worn or not will be based on whether the quality of the machining surface reduces the tolerance. The standard lifespan of diamond cutting tools is very high, and tool wear is also very slow during high-speed cutting. Therefore, in 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 minimum vibration. Due to the minimum surface roughness and highest machining quality at this speed. Obtaining high-quality non-standard machining surfaces is the primary concern for machining non-standard equipment parts. Ultra precision machine tools with good quality, especially those with good dynamic characteristics and low vibration, can utilize high cutting speeds and move processing power.
The selection of machining parameters for non-standard equipment parts mainly includes the selection of cutting tool viewpoint, cutting speed, and cutting depth and feed rate. From past experiences, we know that when processing plastic materials, selecting a tool with a larger rake angle can effectively suppress the formation of chip deposits. This is because as 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.
