How to improve the processing efficiency of precision parts?

How can the processing efficiency of precision parts be improved?

In the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing appearance, and difficulty in chip removal will appear, which seriously affect the quality, production cycle and processing cost of precision parts processing such materials. According to the theories of metal technology, metal cutting, non-standard equipment parts processing principles and other theories, the difficulties in the above-mentioned material processing are analyzed, and a set of effective stainless steel data 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 European and American companies in terms of technological innovation and product development. However, with the influx of foreign capital and the intensification of work competitions, domestic machining of mechanical parts has increased investment in independent development, and has achieved infinite results, especially in the digital display skills and digital display hardware Completed the breaking of measuring tool merchandise. For example, the 2-meter CNC gear measuring instrument successfully developed in China has become a precision measuring instrument that is also extremely competitive in the world. In addition, relying on external forces, it has also provided excellent technical assistance to domestic machining companies. First, most domestic non-standard equipment parts processing companies have introduced many foreign big brand precision machining equipment. This center has many equipment imported from Japan and Germany. With the assistance of external forces, the precision and fineness of products processed by non-standard equipment parts have also been largely improved. The machining of non-standard equipment parts requires super-lubricated machining appearance and high precision machining accuracy, which requires a high standard life span. Whether the tool has worn out will be based on whether the quality of the machining appearance is reduced. 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 cutting speed selected for non-standard equipment parts processing practice is often selected according to the dynamic characteristics of the ultra-precision machine tool used and the dynamic characteristics of the cutting system, that is, the speed with the smallest vibration is selected. At this speed, the surface roughness is the smallest and the processing quality is the highest. Obtaining high-quality non-standard machining appearance is the primary question for non-standard equipment parts processing. The application quality is good, especially the ultra-precision machine tool with good dynamic characteristics and small vibration can use high cutting speed and can travel processing power.

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