【正文】 ct the life of machine tools. So, the choice of tool system, it should be a balanced selection of good products. Process Parameters Cutting speed of highspeed processing of conventional shear velocity of about 10 times For every tooth cutter feed rate remained basically unchanged, to guarantee parts machining precision, surface quality and durability of the tool, Feed volume will also be a corresponding increase about 10 times, reaching 60 m / min, Some even as high as 120 m / min. Therefore, highspeed machining is usually precluded the use of highspeed, feed and depth of cut small cutting parameters. Due to the highspeed machining cutting cushion tend to be small, the formation of very thin chip light, Cutting put the heat away quickly。 If the wiring using a new thermal stability better tool materials and coatings, Using the dry cutting process for highspeed machining is the ideal technology program. Highspeed machining field of application Flexible efficient production line To adapt to the needs of new models, auto body panel molds and resinprevention block the forming die. Must shorten the production cycle and reduce the cost of production and, therefore, we must make great efforts to promote the production of highspeed die in the process. SAIC affiliated with the pany that: Compared to the past, finishing, further precision。 the same time, the surface roughness must be met, the bending of precision, this should be subject to appropriate intensive manual processing. Due to the extremely high cutting speed, and the last finishing processes, the processing cycle should be greatly reduced. To play for machining centers and boring and milling machining center category represented by the highspeed machining technology and automatic tool change function of distinctions Potential to improve processing efficiency, the processing of plex parts used to be concentrated as much as possible the wiring process, that is a fixture in achieving multiple processes centralized processing and dilute the traditional cars, milling, boring, Thread processing different cutting the limits of technology, equipment and give full play to the highspeed cutting tool function, NC is currently raising machine efficiency and speed up product development in an effective way. Therefore, the proposed multipurpose tool of the new requirements call for a tool to plete different parts of the machining processes, ATC reduce the number of ATC to save time, to reduce the quantity and tool inventory, and management to reduce production costs. More monly used in a multifunctional Tool milling boring and milling, drilling milling, drillingmilling threadrange tool. At the same time, mass production line, against the use of technology requires the development of special tools or a smart posite tool, improve, processing efficiency and accuracy and reduced investment. In the highspeed cutting conditions, and some special tools can be part of the processing time to the original 1 / 10 below, results are quite remarkable. HSC has a lot of advantages such as: a large number of materials required resection of the work piece with ultra fine, thin structure of the work piece, Traditionally, the need to spend very long hours for processing mobile work piece and the design of rapid change, short product life cycle of the work piece, able to demonstrate highspeed cutting brought advantages.
