Ball screws are robust and economical linear positioning systems widely employed in high-speed and high-precision machines. Due to precision and stability requirements, the preload force is considered one of the main parameters defining the axial stiffness and the maximum axial load of the ball screw feed drives. In high-speed motions, thermal effects are also considerably relevant regarding positioning...
A ball screw system is widely used for rapid translating precise motion because of its high efficiency and long lifetime. However, a high-speed ball screw drive system naturally produces heat through friction at contact areas, which thereby causes thermal expansion, which adversely affects machining accuracy. In order to achieve high accuracy and great stiffness, the ball screw preload is common solution...
