To achieve its high-performance, high-precision machine tools in China's production of ball screw drive the ratio has been greatly improved. At present, the machine uses a ball screw, a 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. Product structure innovation is to achieve high-speed ball screw foundation Pn and moderately increased the number of lead screw head is to achieve high-speed ball screw best choice. In the early 1989 completed a large lead ball screw "Seven? Five" key, helix angle for f> large lead ball screw 9 ° ~ 17 ° has been able to mass production. However, due to the genetic thread grinder Transmission Error "gene", the greater the lead ball screw manufacturers, the more difficult to improve the accuracy of the lead. Therefore, taking into account the needs of accuracy, Pn lead to moderate increases, such as the nominal diameter and lead the match d0 × Pn to 40mm × 20mm, 50mm × 25mm, 50mm × 30mm and other appropriate best ball screw, wire speed can reach 60m / min or more. The use of double-headed ball of thread in order to increase the effective number of turns carrying the ball screw, ball screw to increase stiffness and load capacity, improve ball nut in high speed running smoothness. Although large lead ball screw (f> 17 °) can achieve higher line speed, but it is difficult to meet the accuracy and processing (minus) speed. Hollow strong cold. At high speed thermal deformation of the screw shaft is a source of processing errors. Meanwhile, in order to improve the system of rigid pre-stretch on the screw shaft will produce heat. Effective way to solve the problem is to heat the coolant through the interior of the hollow screw forced circulation cooling. Hollow screw shaft also helps to reduce the inertia of the high-speed operation, increases torsional rigidity of the screw shaft. Beijing Machine Tool Research Institute in 1997 in cooperation with the Chengdu Tool Research Institute, completed large hollow ball screw hole machining and alloy steel precision deep hole from which to explore the process of experience could be applied in the production of high-speed ball screw.
