This paper analyzes the structure, working principle, advantages and disadvantages of ball screw, and introduces the manufacturing process, testing methods and application fields of ball screw. In order to better illustrate the characteristics of the ball screw structure, this paper also elaborates on the internal structure of the ball screw, bearing selection, thread pair fit and lubrication mode. Finally, through experimental data analysis, the superiority of ball screw in high speed, high precision and high rigidity requirements is verified. Keywords: ball screw; structure; working principle; manufacturing process; bearing selection; thread pair fit; lubrication mode; application field; experimental data,而内循环滚珠丝杠与外循环滚珠丝杠的区别在于，滚珠在内循环滚珠丝杠中在螺纹轴内循环，而在外循环滚珠丝杠中则在螺纹轴外循环, 滚珠丝杠滑台制造需要严格遵守相关的技术标准和质量要求，确保产品的性能和质量符合国际标准, 2. 精度：根据加工要求和精度要求，选择相应精度等级的滚珠丝杠模块,滚珠丝杠的名义尺寸包括直径、螺距和导程,公称直径通常用于确定滚珠丝杠的尺寸，以便进行选择和交流, 许昌滚珠丝杠模组采用滚珠丝杠作为传动元件，通过滚珠与螺纹轴之间的滚动摩擦来实现转换运动
