The invention relates to a clamping device () for a tool () on a machine tool having a holder block () with at least 2, in particular a multiplicity of, apertures () for receiving clamping sleeves (), wherein at least two clamping sleeves () are received in the apertures (). Each clamping sleeve () has a clamping element (), with which a tool (), in particular a shaft () of a tool (), can be clamped. The clamping sleeve () at least partially passes through in each case the aperture () in the holder block () and has, at its end opposite the clamping element (), the rear end, an expansion element () which engages behind the holder block () or a counter-support element () of the holder block ().

Clamping device for a tool on a machine tool

The invention relates to a dental milling machine which has a closed milling chamber (). Said milling chamber has an air inlet opening and an outlet which are substantially opposite each other relative to the milling chamber and generate an air stream. Said air stream sweeps over a machining area in which a milling tool subjects the workpiece to a milling machining step. One end of the milling chamber (), in particular the front end, has a door that can be opened. The base () of the milling space () runs at least partially at an angle and in particular is rounded off and the outlet () is connected to the lowest region of the base ().
