Can be multi-axis linkage and good deep hole cavity integrated cutting capacity mold cavity for the complex space composed of six surfaces and grooves, and many molds have deep hole. In order to achieve the high precision, high speed and high stability of the 3d surface processing, the machine needs multi-axis linkage, and has a good deep hole integrated cutting capacity. Can be used five-axis machining center, in addition to three coordinates of the linear motion, there are two rotary coordinates of the feed movement. Milling head or table can be multi-axis linkage for continuous rotary feed, which is suitable for processing with complex cavity surface of the mold parts. It can be said that the composite processing is one of the development direction of mold processing. Although the machining center has been able to achieve a number of machining processes on a machine tool, but this still can not fully adapt to the mold processing, mechanical processing and electrical, chemical, ultrasonic and other different principles of processing methods, both two or more process characteristics Of the composite processing in the future mold manufacturing will have broad prospects
