value of the servo system reaches above 30000h, demonstrate very high dependability . In order to realize high-speed, high finish machining, if the part of function related to it is electric main shaft, straight line electrical machinery get fast development, the application is expanded further .1.2 Link and process pound to process the fast development of the lathe in5 axes Adopt 5 axles to link the processing of the three-dimensional curved surface part, can cut with the best geometry form of the cutter ,not only highly polished, but also efficiency improves bya large margin . It is generally acknowledged, the efficiency of an5 axle gear beds can equal 23 axle gear beds, is it wait for to use the cubic nitrogen boron the milling cutter of ultra hard material is milled and pared ata high
