摘要
The invention discloses a device (10) for clamping particularly an eye glass lens blocked on a block piece for processing and/or coating said eye glass lens, comprising a receiving space (34) having a center line (M) for a clamping section of the block piece, and a plurality of clamping surfaces (36) provided in a boundary region of the receiving space, which may optionally be engaged in the clamping section of the block piece in order to clamp the block piece. In order to avoid excessive deformation of the clamped block piece, the clamping surfaces are positioned opposite of each other in pairs at a radial distance to the center line and can be displaced optionally toward or away from each other by means of a clamping piece (38) in order to clamp the clamping section of the block piece by way of clamping forces (F), which are substantially oriented in a tangential direction at a radial distance to the center line, or in order to release the block piece.
