If it is necessary to use the auxiliary units unloaded ball screw, otherwise the ball may fall off when loading and unloading. Nut handling should note the following: (1) should be less than the outer diameter of the auxiliary set screw bottom diameter of 0.1-0.2mm. (2) Auxiliary sets in use must try to be screw threaded shaft shoulder. (3) When unloading, not excessive force polishing TBI ball screw supply, so as not to damage the nut. (4) into the mounting holes to avoid collision and eccentric. 1) The ball screw nut and a support system to detect and repair gaps appear when CNC machine reverse error, unstable positioning accuracy, when crossing quadrant marks appear, the first to be detected screw system there is no gap. Detection methods are: Using a dial indicator on the end of the center hole with the ball screw ball screw grinding agent, measuring the axial play of the screw in Guangzhou grinding ball screw, the other dial indicator measuring table moves . Reverse rotation of the screw, observe two dial indicator reflects the values, confirm the fault location changes based on different values.
