Ball screw nut and a support system to detect and repair gaps appear when CNC machine tools reverse error, positioning accuracy is unstable, too quadrant marks appear Chengde Ball enterprise, we must first detect screw system there is no gap. Detection methods are: using a dial indicator with the ball on the end of the screw in the center hole, measuring the axial play of Chengde Ball screw production, the other dial mobile measurement workbench. Reverse rotation of the screw, observing the two dial indicator reflects the value of Chengde ball screw supply, confirm the fault location based on the value of different changes. Double-nut ball screw gap of inspection and maintenance by detecting the ball screw, lead screw if to confirm the fault is not due to traverse due. It would have to consider whether it is creating a gap between the screw nut, the detection method to detect this situation is basically the same as the screw ran. Workbench with a dial indicator to measure connected with the nut, forward and reverse rotation of the screw, detects the maximum gap between the screw and nut, and then make adjustments.
