To achieve its high-performance ball screw, Chinese manufactured using high-precision ball screw machine at the drive ratio has been greatly improved. At present, the machine uses a ball screw ball screw employed, have lower domestic prices, there are high precision imported products in Japan and Europe. The use of imported products are often those on processing speed, accuracy, longevity and stability of the machine have higher requirements. Ball screw determine the main technical parameters: (1) Lead Ph drive according to the requirements of the machine, load size, and transmission efficiency and other factors considered OK. Generally selected, press the machine to determine the transmission requirements, the formula is: Ph≥vmax / nmax (10). Where: vmax- fastest machine table feed speed ball screw characteristics, mm / min; nmax- drive motor maximum speed ball screw slide, r / min. Under the resolution of the system to meet the control requirements of the premise, Ph should take a larger value. (2) the choice of ball screw nut ball screw for CNC machine tools due to stiffness have higher requirements, so pay attention to the choice of its stiffness guarantee nut. Recommended by high stiffness required to select preloaded nut type. Where the outer loop of the end of the tube-type double flange nut most widely used. It is suitable for heavy duty transmission, high-speed driving and precision positioning system. And has a unique advantage in the large lead, small and long lead screw, and the more economical.
