With the improvement of the performance of the core processor of the CNC system, the feed speed limit of the high-speed machining center can reach 80 m / min, and the idle speed can reach about 100 m / min. At present, many automobile factories in the world, including Shanghai General Motors Company in China, have partially replaced modular machine tools with production lines composed of high-speed machining centers. The feeding speed limit of hypermach machine tool of Cincinnati company is 60m / min, the speed is 100M / min, the acceleration is 2G, and the spindle speed has reached 60000r / min. It takes only 30 minutes to process a thin-walled aircraft part, while it takes 3 hours for the same part to be processed on a general high-speed milling machine and 8 hours on a general milling machine. Due to the specialization of each component of the mechanism, under the development of professional spindle factory, spindle high-speed is increasingly popular. In the past only used for high-speed automobile industry models (15000 rpm or more), now has become a necessary mechanical product requirements.
