Kammerer Gewindetechnik presents a novel feedback principle for high-performance ball screw drives in machine tools (WZM). The feedback system of the ball reduces the noise and internal friction in the ball chain of the screw drive. It is being developed as part of a research cooperation project involving the Institute of Production Technology of the Karlsruhe Institute of Technology (KIT). The aim of the project is the construction of system components for the WZM-Bau.
As a further co-operation partner E. Reitz Natursteintechnik develops a novel, cement-bound concrete (UHPC) as material for the production of the machine bed on which the ball screw drive is mounted. The interaction of ball screw and machine bed in terms of damping, stiffness, temperature response and other parameters is currently being researched at KIT. The reference forms a conventional machine bed designed as a welded steel construction, which is available for comparison in the same dimension.
"With the combination of machine bed and drive technology from a single source, we want to meet the demands of a number of machine manufacturers who demand a complete system," explains Peter Kammerer, technical manager of the Hornberger thread technology specialist. "Discussions in drive technology show that there are still potentials for ball screw drives that have to be taken advantage of in order to strengthen the ball screw drive as a drive element. Despite alternative drive technology, the ball screw drive continues to be regarded as the most important drive element in WZM. "
