Since the mandrel and positioning sleeve positioning sleeve and bearing bore is supported at both ends and in the middle of the nut seat hole with the gap exists, it tends to support a larger bearing bore concentricity error after installation and nut seat hole, resulting in screw around increases, the radial offset load increases, causing the screw shaft of all aspects of temperature, heat distortion becomes large and the transmission torque increases and other serious consequences, leading to the servo motor overload, overheating, servo system alarm affecting the normal operation of the machine. In addition, both ends of the bearing bore and the intermediate nut seat hole can not accurately measure the actual difference, thus affecting the further precise adjustment. For the three coordinate directions stroke larger CNC machine tools and machining centers, as required more than 1500mm above the mandrel, processing difficulties, difficult to ensure accuracy, and therefore can not use the method of alignment with the mandrel and positioning sleeve carried the ball screw installation.
