Abstract
Disclosed is a clamping device () for clamping a toolholder of a drilling, milling or grinding tool in a balancing machine, comprising a receiver unit () having a receiving opening () for the coupling shaft of the toolholder and a collet (), in which the shaft () of an actuator () for actuation of the collet () is slidably guided in a centrally located bore () of the receiver unit (). The shaft () has at its one end a load-applying body () upon which a plurality of compression springs () take support to enable the collet () to be tightened. The compression springs () are arranged and/or configured in such a way that the spring loads acting on the load-applying body () with the collet () tightened act on the load-applying body () asymmetrically relative to the axis of the shaft ().
