reduce the cutting force, increase the life of tools, and reduce the cost.   Using five-axis linkage machine tool to process the mold can quickly complete the mold processing with fast delivery and good quality, also make the mold processing and modification much easier. In the traditional mold processing, the vertical machining center is generally used to complete the milling of workpiece. With the continuous development of mold manufacturing technology, some weakness of vertical machining center itself becomes more and more abvious. Modern mold processing generally uses the ball-end milling cutters, which brings in abvious benefits in the mold processing. But if the vertical machining center is used, the linear speed of bottom surface is zero, then the smooth of bottom surface will be very poor. However, if you use the processing technology of four or five axis linkage machine tool, the above defects will be avoided.
