Clamping system made from shape memory alloys

Tool clamping systems have a considerable influence on the precision and efficiency of machining processes. In conventional clamping systems, the clamping force required to fix the tool holder is applied using spring assemblies. The force required to release the holder is realized with high energy consumption by a hydraulic release unit. Ott-Jakob Spanntechnik and the Institute of Production Engineering and Machine Tools (IFW) at Leibniz Universität Hannover are therefore researching a new type of clamping concept based on bidirectional actuators made from shape memory alloys.
