Coiled spring expansion mandrels and clamping sleeves are used for tensioning in lathes and milling machines, mandrels are used to achieve the exact tension in drillings, and clamping sleeves are used for tensioning bolts. They produce an exactly centrical effect and

make it possible to achieve significantly larger changes in diameter than e.g. wedge clamping or hydraulic expansion systems. They produce large forces due to a spatial toggle lever polygon of forces.
