As the ceaseless face city of new product, market competition is increasingly intense, the demand of people also increases increasingly, want when be economical is saved, handle affairs more, must find more efficient producer formula. One of main motive force that make technical progress today are integrated. To realize fast production, the process designing that often needs to answer complex geometrical form and take time works, optimize milling craft to have challenge sex especially so. In addition, milling machine raises high yield very hard commonly can, the enterprise shortens time, the Chongzhongzhi that solving these problems also is technical research and development all the time is heavy. Choose industry of compound treatment machine tool to need to be able to be offerred accurate, capable the equipment that spends with the high capacity of high speed milling, high speed (graph 1) . However, cost is a factor that must consider, a lot of enterprises cannot pay a these functions, how to mix the milling ability of vertical machining center so fast union becomes the freeboard of bore tap center together at present most the issue that needs to solve, still include tigidity to owe among them the beautiful, time that change a knife grows and the surface is bright and clean degree of difference. Graph machine tool of 1 compound treatment is machining all sorts of size mould respects to provide better performance. These machine tools can undertake small and deep milling works, have cutting tool small, main shaft rotate speed is high, the characteristic with large work area solves one of methods of these problems to use compound treatment machine tool namely. The characteristic of this kind of machine tool is to have more advanced opportunity process capability, production enterprise can a certain number of flow and cutting technology mix are in a machine tool, use standard, off-the-peg tooling, the economy when the province, the effect is distinct. Compound treatment can say is the domain that business is interested in mould manufacturing industry very much, because it can decrease greatly,discharge benchwork working procedure even. Its are true value system applies in finish machining now in. The concerned consideration element of the machine tool looks for rate of a market, tigidity and high dynamic performance the machine tool at an organic whole. The X axis that this machine tool wants to have stroke of C frame design, 700mm, cover an area of 5.

4ft2 (1ft=304.

8mm) and can to load amounts to 880lb (1lb=0.

45kg) and the workbench that does not have any speed limit. Most crossed workbench, still can maintain precision impossibly below high speed circumstance normally. Design what notional ability fits high speed pattern correctly to make, because it can be offerred,machine the tigidity that place of large Injection Mold Tooling needs and dimension space. Tigidity was very by the machine tool minutely whether can compare cubic metre of more of cutting of another machine tool centimeter metallic place decision. The tigidity that raises a machine tool also is meant have taller precision and less vibration, have better exterior quality and longer cutting tool life thereby. A when reduce benchwork particularly main factor is main shaft. Although most person is met a high speed main shaft and cutting aluminium (or bottle embryo mould) connection is together, but when creating nonferrous metal pattern, the main shaft of rotate speed 24000rpm also is indispensable. Those who machine mixed pattern model the cutting tool that antrum needs small diameter, use diameter 0.

The cutting tool of 125in should realize 800ft2 (1ft2=0.

093m2) cutting efficiency, achieve 24000rpm with respect to rotate speed of requirement main shaft. Another of compound treatment machine tool important characteristic is: The torque that its main shaft should offer with place of standard main shaft in the torque when low rotate speed is similar, this is to shorten when finish machining handling time and the compromise that undertake. Trade knife unit plus high speed, "Bits arrives bits " the time that change a knife can be controlled in 1.

5s (graph 2) . Graph the 2 compound treatment machine tools that search to have exceedingly good high speed to trade knife unit, the time changing a knife of machine tool of a few compound treatment is only 1.

Because 5s is high-powered compound treatment machine tool is to be large quantities of quantities to production or automation are machined and be designed only, discharging bits is another element that wants a consideration. Improvement cuts bits shedding and the recipe that raise precision to optimize workbench structure namely, triangular workbench and good thermal stability can be improved cut bits to flow. To optimize the productivity in milling and respect of high speed cutting and profit margin, lv of die manufacturer take an examination uses high speed compound treatment milling machine. New technology had removed an obstacle, improved technology significantly, machine treatment exercise of future will have more high accuracy, more when the province, more economy. CNC Milling
