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., 2. 材料：滚珠丝杠可以采用不同材料制造，不同材料的价格也会有所不同,其中，C0为最高精度等级，误差小于0.01mm；C1为高精度等级，误差小于0.03mm；C2为中等精度等级，误差小于0.05mm；C3为普通精度等级，误差小于0.1mm；C5为低精度等级，误差小于0.2mm, 6. 材质：通常以钢铁、不锈钢等为主，根据使用环境和要求选择适当的材质,其基本原理是利用滚珠在导轨和螺纹母线之间运动，从而实现转动传动, 注：以上标准仅供参考，不同厂家和行业对滚珠丝杠的光洁度标准可能存在差异,镇江市是中国江苏省的一个城市，也是一个重要的制造业中心,滚珠丝杠通常使用合成润滑油，因为它们具有较高的性能和耐用性
