导向装置一般由导向轴承、导向套、导向板等组成,长滚珠丝杠模组是一种由滚珠丝杠、导轨、电机等组成的机械传动装置,同时，滚珠丝杠的使用寿命相对较长，可以减少设备维修和更换的次数，提高设备的可靠性和稳定性,河南升降滚珠丝杠模组是一种机电一体化的装置，主要由电机、减速器、滚珠丝杠、导轨、限位开关、控制器等部件组成,这是一种滚珠丝杠规格的命名方式，具体含义如下： GQ50表示丝杠的直径为50毫米； x10表示每毫米滚珠数量为10个； 一3表示丝杠的导程为3毫米, 4. 进行切削操作，让车刀沿着滚珠丝杠的轴线进行切削, 5. 精密加工：在数控机床上，将六角形的棒材进行精密加工，包括车削、铣削、钻孔等工序，使其成为一定精度和尺寸的滚珠丝杠, 关键词：机床；滚珠丝杠；选型；性能指标；应用案例 Abstract This paper studies the selection of heavy-duty ball screw for machine tools. Through the analysis of the structure, working principle, selection parameters and other aspects of ball screw, the factors to be considered in selection are proposed, and the practical calculation and analysis are carried out with specific application cases. Firstly, the basic structure and working principle of ball screw are introduced, and its advantages and disadvantages are analyzed, as well as the comparison with other types of screw. Then, according to the performance indicators and selection parameters of ball screw, the factors to be considered in selection are proposed, including load, speed, accuracy, environmental conditions, etc. Next, through the practical calculation and analysis of the selection of ball screw for the spindle of a CNC lathe, the feasibility and accuracy of the selection are verified. Finally, the application prospect and development trend of ball screw are discussed. Keywords: machine tool; ball screw; selection; performance indicators; application case, 4.将滚珠丝杠插入安装座的孔中，并用拧紧工具将其拧紧,当制动器被激活时，制动板与制动齿轮之间产生摩擦力，从而使滚珠丝杠停止旋转
