因此，SFU和DFU的选择应根据具体的应用场景和要求来确定, 6. 根据需要涂色或者阴影处理，使绘制的滚珠丝杠更加逼真,控制器可以采集测量头的数据，并进行数据处理和显示,滚珠丝杠扭力推导公式如下： T = (F × P) / (2 × π × η × tanα) 其中，T为滚珠丝杠的扭力，单位为牛顿米(N·m)；F为作用在滚珠丝杠上的力，单位为牛顿(N)；P为滚珠丝杠的螺距，单位为米(m)；η为润滑油的黏度，单位为帕斯卡秒(Pa·s)；α为滚珠丝杠的螺旋角，单位为弧度(rad), 综合以上因素，选择合适的滚珠丝杠精度等级可以提高工作效率、降低成本和提高产品质量,它能够实现高精度的焊接操作，提高焊接效率和质量,1. 首先将滚珠丝杠和钢珠清洗干净，确保表面无杂质和污物, 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.
