Ball screw drive manufacturer _ Korea Taiwan Machinery (certified) _ Kaiping ball screw

 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 ball screw, 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" and lead the greater accuracy more difficult to increase 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 ball screw agents, 50mm × 30mm and other appropriate line speed are up to 60m / min or more. The use of two-start thread is the number of turns in order to increase the effective bearing balls, thereby enhancing the stiffness and load screw vice supply capacity of the ball screw, the ball nut in improving high speed running stability. 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 had experience in 1997 in cooperation with the Chengdu Institute of ball screw machining tools to complete large hollow ball screw hole machining and alloy steel precision deep hole from which to explore the process, in the production of high-speed ball screw the application. Because of the mandrel and positioning units, positioned at both ends of the supporting sleeve and bearing bore and in the middle there is a nut seat hole with the gap, tend to make greater support bearing bore concentricity error after installation and nut seat hole, causing screw around increases, the radial offset load increases, causing the screw shaft various aspects of temperature, heat distortion becomes large and transmission torque increases and other serious consequences, leading to the servo motor overload, overheating, servo system alarm affecting the normal operation of the machine. In addition, both ends of the bearing bore hole and intermediate filaments female real difference can not be accurately measured, thus affecting more precise adjustments. For the three coordinate directions stroke larger CNC machine tools and machining centers, as required in the mandrel more than 1500mm, processing difficulties, difficult to ensure accuracy, and therefore being unable to find a method of using the mandrel and positioning sleeve conducted with ball screw installation.
