The use of five-axis CNC machining center technology to process molds can reduce the number of fixtures. In addition, because the five-axis linkage machine tool can save many special tools in processing, it reduces tool costs. The five-axis linkage machine tool can increase the effective cutting edge length of the tool during processing, reduce the cutting force, increase the service life of the tool, and reduce the cost. Using five-axis linkage machine tool to process molds can quickly complete mold processing, fast delivery, better guarantee the quality of mold processing, make mold processing easier, and make mold modification easier. In traditional mold processing, a vertical machining center is generally used to complete the milling of the workpiece. With the continuous development of mold manufacturing technology, some of the weaknesses of the vertical machining center itself have become more and more obvious. Modern mold processing generally uses ball-end milling cutters to process. Ball-end milling cutters bring obvious benefits in mold processing. However, if a vertical machining center is used, the linear velocity of the bottom surface is zero, so the bottom surface finish is very poor. , If you use four-axis or five-axis linkage machine tool processing technology to process molds, the above shortcomings can be overcome.
