In the process of non-standard Precision Machining Parts, there will be common problems such as accelerated tool wear, poor machining surface integrity, and difficulty in chip removal, which seriously affect the quality, production cycle and processing cost of precision parts processing of such materials. According to metal technology, Metal cutting, non-standard equipment parts processing principles and other theories analyze the above-mentioned difficulties in processing materials, and explore a set of effective drilling, reaming, and boring processing skills for stainless steel materials. China's machinery manufacturing industry is bound by skills and talents, and is in the process of technological innovation. In terms of product research and development, it is difficult to compete with large companies in Europe and the United States. However, with the influx of foreign capital and the intensification of work competition, domestic Machinery Parts processing work has increased investment in independent development, and has achieved infinite results, especially The mechanical measuring tool and measuring instrument manufacturing company has achieved breakthroughs in digital display technology 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 for competition strength.

With the help of external force, it has also provided excellent assistance to domestic machining companies in terms of skills (whether it is Metal Machining or plastic machining). Nowadays, most of the non-standard equipment parts processing companies in China have introduced many large foreign companies. Brand precision machining equipment. There is no shortage of equipment imported from Japan and Germany in this center. With the assistance of external forces, the accuracy and quality of the products processed by non-standard equipment parts have also been greatly improved.

The machining of non-standard precision parts requires ultra-lubricated surface and high machining accuracy. This 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 machined surface is reduced out of tolerance. The standard life of diamond tools is very high, and the tool wear is very slow during 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 selection of processing parameters for non-standard precision parts should include the selection of cutting tool viewpoints, the selection of cutting speed, and the selection of cutting depth and feed rate. From past experience, we know that when plasticizing materials, if a tool with a larger rake angle is selected, the formation of built-up edge can be effectively suppressed. This is when the rake angle of the tool increases, the cutting force decreases, the cutting deformation is small, and the tool and chips The contact length is shortened, reducing the base formed by the built-up edge.
