Disclosed is a mounting device () including a receiving opening () with a circular inner locating surface () which is coaxial with the axis of rotation () and serves for engagement with radially outer vertices () of the polygon profile of a holding pin (). Arranged adjacent to the inner locating surface is a positioning disk () which has an opening () coaxial with the axis of rotation () and of such polygonal shape and size that the polygon profile of the holding pin () engaging in the opening () is supported in the opening () in a manner preventing relative rotation.

Mounting device for a rotary spindle of a balancing machine

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 ().
