Abstract

The invention relates to a speed-changing shearing or forming active element insert which is designed to be detachably connected to an active element receptacle of a machine tool, the speed-changing shearing or forming active element insert having a speed-changing unit which is in the form of a hydraulic force/distance transducer, the force/distance transducer comprising a housing, the housing interior of which is supplied with a hydraulic fluid, and the force/distance transducer comprising a first piston which is in oo contact with the hydraulic fluid via one piston end and a second piston which is in contact with the hydraulic fluid via one piston end and the cross-sectional area of which is smaller than the cross-sectional area of the first piston. The invention also relates to the use of the speed-changing changing shearing or forming active element insert in a machine tool.
