On the Test Bench - Characteristics and Requirements of High-Performance Ball Screws

Der Konstrukteur Jan./Feb. 2013

The successful operation of sophisticated machine tools depends on the performance of the ball screws used, among other factors. In addition to a sophisticated design and material selection, the exact design, processing and quality assurance measures during assembly and installation also play an important role. In addition to a wealth of other design and technical features, the nut preload and the idle torque are two important quality parameters that significantly determine the running behavior, the thermal growth and the service life of a ball screw.
