同时，需要定期检查和维护贴片机的滚珠丝杠，确保其正常运转和使用寿命,SFU1204代表丝杠的直径为12mm，螺距为4mm, 3. 运动速度：滚珠丝杠的运动速度需要根据具体的应用场景来确定，通常需要根据滚珠丝杠的规格和最大转速来计算, 关键词：滚珠丝杠；数控机床；应用；设计 Abstract: This paper studies the application and design of ball screw in CNC machine tools. Firstly, the structure and principle of ball screw are introduced, and its advantages and disadvantages in CNC machine tools are analyzed. Then, the working principle of CNC machine tools is briefly introduced, and the design of ball screw in CNC machine tools is studied in detail. Specifically, it includes the selection of ball screw, the design of transmission system, the calculation of transmission efficiency, and the optimization of transmission system. Finally, the research results are summarized, and the application and research direction of ball screw in CNC machine tools in the future are prospected. Keywords: ball screw; CNC machine tool; application; design, 2. 滚珠丝杠直径：滚珠丝杠的直径与承载能力有关，需要选用直径较大的滚珠丝杠, 3. 使用扳手和扳手套筒拧下原螺母,螺纹杆上有螺纹，螺纹母内部带有与螺纹杆相同的螺纹，滚珠则在螺纹杆和螺纹母之间滚动，从而实现传递力和运动的目的,一般来说，滚珠丝杠的长度越长，刚度越大，因为长度越长，滚珠丝杠会有更多的弯曲和变形，从而使其刚度增加, 3. 安装滚珠丝杠和导轨，并确保它们之间的对齐和平行度,上海线性滚珠丝杠具有精度高、负载能力大、寿命长等特点，广泛应用于机床、自动化设备、工业机器人等领域
