Dongguan CNC machining plant adopts 5-axis linkage to process 3D curved surface parts, which can be cut with the best geometric shape of cutting tool. It not only has high finish, but also greatly improves efficiency. It is generally believed that the efficiency of one 5-axis linkage machine tool can be equal to that of two 3-axis linkage machine tools. Especially when using cubic boron nitride and other superhard material milling cutter for high-speed milling hardened steel parts, 5-axis linkage machining can play a higher benefit than 3-axis linkage machining. In the past, due to the complexity of 5-axis CNC system and host structure, the price of Dongguan CNC processing plant was several times higher than that of 3-axis CNC machine tools, and the programming technology was difficult, which restricted the development of 5-axis CNC machine tools.
Due to the appearance of motorized spindle in Dongguan CNC plant, the structure of compound spindle head for 5-axis linkage machining is greatly simplified, its manufacturing difficulty and cost are greatly reduced, and the price gap of CNC system is narrowed. Therefore, it promotes the development of compound spindle head type 5-axis linkage machine tool and compound machining machine tool (including 5-face machining machine tool). At EMO2001 exhibition of Dongguan CNC processing plant, the 5-face processing machine of new Japan machine tool adopts compound main shaft head, which can realize the processing of 4 vertical planes and any angle, so that the 5-face processing and 5-axis processing can be realized on the same machine tool, and the processing of inclined plane and inverted cone hole can also be realized. Dmuvolution series machining center is exhibited by DMG company of Germany. It can realize 5-face machining and 5-axis linkage machining under one clamping. It can be controlled directly or indirectly by CNC system or CAD / CAM
