Highspeed milling—— 高速銑削 Highspeed machining is an advanced manufacturing technology, different from the traditional processing methods. The spindle speed, cutting feed rate, cutting a small amount of units within the time of removal of material has increased three to six times. With high efficiency, high precision and high quality surface as the basic characteristics of the automobile industry, aerospace, mold manufacturing and instrumentation industry, such as access to a wide range of applications, has made significant economic benefits, is the contemporary importance of advanced manufacturing technology. For a long time, people die on the processing has been using a grinding or milling EDM (EDM) processing, grinding, polishing methods. Although the high hardness of the EDM machine parts, but the lower the productivity of its application is limited. With the development of highspeed processing technology, used to replace highspeed cutting, grinding and polishing process to die processing has bee possible. To shorten the processing cycle, processing and reliable quality assurance, lower processing costs. 1 One of the advantages of highspeed machining Highspeed machining as a dieefficient manufacturing, highquality, low power consumption in an advanced manufacturing technology. In conventional machining in a series of problems has plagued by highspeed machining of the application have been resolved. Increase productivity Highspeed cutting of the spindle speed, feed rate pared withtraditional machining, in the nature of the leap, the metal removal rate increased 30 percent to 40 percent, cutting force reduced by 30 percent, the cutting tool life increased by 70% . Hardened parts can be processed, a fixture in many parts to be pleted rough, semifinishing and fine, and all other processes, the plex can reach parts of the surface quality requirements, thus increasing the processing productivity and petitiveness of products in the market. Improve processing accuracy and surface quality Highspeed machines generally have high rigidity and precision, and other characteristics, processing, cutting the depth of small, fast and feed, cutting force low, the workpiece to reduce heat distortion, and high precision machining, surface roughness small. Milling will be no highspeed processing and milling marks the surface so that the parts greatly enhance the quality of the surface. Processing Aluminum when up , pieces of steel processing at up to ~ . Cutting reduce the heat Because the main axis milling machine highspeed rotation, cutting a shallow cutting, and feed very quickly, and the blade length of the workpiece contacts and contact time is very short, a decrease of blades and parts of the heat conduction. Highspeed cutting by dry milling or oil cooked up absolute (mist) lubrication system, to avoid the traditional processing tool in contact with the workpiece and a lot of shortings to ensurethat the tool is not high temperature under the conditions of work, extended tool life. This is conducive to processing thinwalled parts Highspeed cutting of small cutting force, a higher degree of stability, Machinable with highquality employees pared to the pany may be very good, but other than the pany39。s employees may Suanbu Le outstanding work performance. For our China practice, we use the models to determine the method of staff training needs are simple and effective. This study models can be an external object, it can also be a bination of internal and external. We must first clear strategy for the development of enterprises. Through the internal and external business environment and
