How to improve the machining efficiency of precision parts
release time: 2017/3/18 non-standard equipment parts processing will appear in the process of tool wear speed up, poor processing appearance integrity, chip, overcoming difficulties, such as the universal question, seriously affect the quality of such data precision parts processing, production cycle and the processing cost. In accordance with the skills to learn metal, metal cutting, non-standard equipment parts processing principle of theory of the above material processing difficulties are analyzed, explore a set of effective stainless steel materials, drilling, reaming, boring and processing skills. Machinery manufacturing in China are under the yoke of skills and talents, and skills in innovation and product research and development, it is difficult to compete with Europe and the United States of big company. But with the influx of foreign capital, competition intensified, domestic mechanical parts processing work increasing investment on independent development, has achieved the endless results, especially the machinery production company in the digital display skills and digital display measuring instrument hardware measuring finished break goods. As the current domestic successful development of 2 meters CNC gear measuring instrument, become highly competition strength in the international community of precision measuring instruments. Other rely on outside force, also to the domestic mechanical processing company with great help on skills, now most of the domestic first non-standard equipment parts processing company introduced many foreign brands more precision machinery processing equipment. That is not center with Japan, Germany imports of equipment. With the help of outside force, but also greatly cut the non-standard equipment parts processing precision of the commodity and identity. Non-standard equipment parts processing requirements are super lubrication precision machining surface and high precision precision machining accuracy, it needs a knife with high standard become old, yea, cutting tool is already wear and will be processed based on appearance quality is lower than poor. The standard of the diamond tool stature is very high, high speed cutting tool wear is also very slow. And ultra precision cutting, the cutting speed is not the restriction of the cutting tool life, this is different from the general rules of cutting. Non-standard equipment parts processing practice selected cutting speed, often is based on the use of ultra precision machine tool dynamic characteristics and the dynamic characteristics of cutting system selected, the selected vibration minimum speed. Because when the rotating speed minimum surface roughness, processing the highest quality. To obtain high quality of non-standard mechanical processing appearance are standard equipment parts processing primary question. Use good quality, especially the good dynamic characteristics, small vibration of ultra-precision machine tool can use high cutting speed, can travel processing power. Non-standard equipment parts processing parameter selection first contains a point on the cutting tool selection, cutting speed selection and cutting depth and feed speed selection, etc. We know from previous experience in the processing of plastic materials, if choose larger rake Angle of cutting tool can be useful to bay the devolop tumor formation, it is cutting tool rake Angle increases, the cutting force decreases, and the cutting deformation, cutting tool and chip contact length shorten, reduced the constitute the basis of the devolop tumor.
