国内与国外滚珠丝杠磨削技术有哪些差距？

In recent years, the grinding technology of ball screws has made great progress in foreign countries, and the following are some of the latest developments: 1. High-speed grinding technology: With the development of high-speed and super-high-speed grinding technology, the grinding speed of ball screws has been greatly improved. The grinding speed of high-speed grinding can reach 200 m/s, and the grinding speed of super-high-speed grinding can reach 500 m/s. 2. Nano-grinding technology: Nano-grinding technology can achieve high-precision grinding with micro-scale abrasives. The surface roughness of the ground ball screw can reach Ra0.01μm, and the accuracy of the screw can reach IT0.1 level. 3. Combined grinding technology: The combined grinding technology of ball screw can not only improve the efficiency of grinding, but also improve the accuracy and surface quality of the screw. The combined grinding technology includes multi-axis grinding, multi-grinding wheel grinding, and multi-process grinding. 4. Intelligent grinding technology: With the development of intelligent grinding technology, the grinding process of ball screws can be monitored and controlled in real time, which can improve the stability and consistency of the grinding process, and improve the quality of the ground ball screws. Overall, the above-mentioned advanced grinding technologies have greatly improved the precision, efficiency, and quality of ball screw grinding, and have played an important role in promoting the development of precision machinery and equipment.
