Non-standard equipment parts processing process will present tool wear accelerated, poor processing appearance integrity, chip removal difficulties and other common problems, seriously affecting the quality of such materials precision parts processing, production cycle and processing costs. According to the theory of metal technology, metal cutting, non-standard equipment parts processing principle of the above material processing difficulties to analyze, explore a set of effective stainless steel material drilling, reaming, boring processing skills. China's machinery manufacturing industry is bound by skills and talents, in the innovation of skills and product development, it is difficult to compete with the large companies in Europe and the United States. But with the influx of foreign capital, the intensification of the work competition, domestic precision parts processing plant work on independent development to increase investment, has achieved endless results, especially in the production of mechanical gauges gauge companies in the digital display skills and digital hardware gauges commodities to complete the breakthrough. Such as the current domestic success of the development of 2 m cnc gear measuring instrument, into the international also very strong competition in the precision measuring instruments. In addition, by virtue of external forces, but also to the domestic machining companies in the skills have excellent assistance, first now most of the domestic non-standard equipment parts processing companies more than the introduction of a number of foreign big brands of precision machining equipment. This center has no shortage of Japan, Germany imported equipment. With the assistance of external forces, but also to a large extent into the non-standard equipment parts processing out of the precision and color of the goods.
Non-standard equipment parts processing needs to get super-lubricated processing appearance and high processing accuracy, which requires the knife has a high standard life, the tool is not worn, will be based on the processing appearance quality is not reduced super poor. Diamond tool standard life is very high, high-speed cutting tool wear is also very slow. Therefore, ultra-precision cutting, cutting speed is not subject to the constraints of tool life, which is different from the general cutting rules.
Non-standard equipment parts processing practice selected cutting speed, is often based on the use of ultra-precision machine tools and dynamic characteristics of the cutting system to select the dynamic characteristics, that is, to select the minimum vibration speed. Because at this speed the appearance of the smallest roughness, the highest quality machining. Obtaining a high quality non-standard machined appearance is the primary concern of non-standard equipment precision parts machining plants. The use of good quality, especially the dynamic characteristics of good, small vibration of ultra-precision machine tools can be used at high cutting speeds, can improve the power of processing.
The selection of non-standard equipment parts processing parameters include the selection of the cutting tool point of view, the selection of cutting speed and depth of cut and feed rate selection. From the past experience we know that in the processing of plastic materials, if you select a larger front angle of the tool can be useful to press down the composition of the chip tumor, which is the front angle of the tool increases, the cutting force is reduced, cutting deformation is small, the tool and chip contact length becomes shorter, reducing the basis for the composition of the chip tumor.
