Ball screw main technical parameters to determine: (1) Lead Ph considered in accordance with the requirements of the machine drive ball screw, load size, and other factors to determine the transmission efficiency. Usually the choice of Dongguan ball screw press machine drive required to determine, the formula is: Ph≥vmax / nmax (10). Where: vmax- fastest machine table feed speed, mm / min; nmax- drive motor maximum speed, r / min. In the resolution of the system to meet the control requirements of the premise, Ph should take a larger value. (2) selection of a ball screw nut ball screw for CNC machine tools due to the rigidity have higher requirements, so pay attention to the stiffness of assurance when choosing nut. Recommended by high stiffness required to select a preloaded nut type. Wherein the outer loop of the end of the cannula style double flange nut most widely used. It is suitable for heavy loads drive, high-speed driving and precision positioning systems. And it has a unique advantage in the large lead, small lead and long thread, and more economical. 1) The ball screw nut and a support system to detect and repair gaps appear when CNC machine reverse error, unstable positioning accuracy, silent ball screw 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 in Suzhou, measuring screw axial movement, the other mobile measuring station dial indicator. Reverse rotation of the screw, observe two dial indicator reflects the values, confirm the fault location changes based on different values.
