The system uses a stepper motor to drive the ball screw for positioning, with the advantages of high precision, fast speed, quietness, and long service life. The design mainly involves the selection of ball screws, the drive of stepper motors, the selection and installation of sensors, and the design of control systems. Through experimental verification, the system has high positioning accuracy and stability, and can be used in various occasions that require high-precision positioning. Keywords: ball screw; stepper motor; positioning system; control system; sensor,天津研磨滚珠丝杠精度等级一般按照国际标准GB/T 11804-2000进行分类，主要包括以下几个等级： 1. 一般精度等级：精度在0.05mm/m以内, 步骤二：用直尺或平板检查工作台固定板的平整度，确保误差不超过0.05mm, 3. 将新的滚珠丝杠和支架安装到打印机内部，注意安装方向和位置,调整方法是在轴承两侧加装弹性垫圈或弹性套管，通过调整垫圈或套管的厚度来调整预紧力,1. 确认滚珠丝杠的型号和规格，以及所需的安装工具和设备,1. 清洁：首先需要清洁滚珠丝杠，使用无油清洁剂或酒精擦拭干净，确保滚珠能够自由运动
