The clamping apparatus comprises a clamping chuck and a work piece carrier releasably connected thereto. The clamping chuck is provided with a central opening for receiving a clamping pin at- tached to the work piece carrier. The central opening of the clamping chuck has a conical inserting portion, and the clamping pin has at least one surface portion corresponding in shape to the conical inserting portion, or several surface portions for align- ing the clamping pin in X- and/or Y-direction. The clamping chuck comprises a clamping mechanism for clamping the clamping pin. The top of the clamping chuck is provided with at least one surface portion serving as a Z-stop member. The clamping pin is dimen- sinned such that, prior to activating the clamping mechanism, a gap exists between the flat bottom surface of the work piece car- rier and the surface portion of the clamping chuck serving as a Z- direction stop member. The clamping pin and/or the region around the central opening of the clamping chuck is/are adapted to be elastically deformed upon activation of the clamping mechanism to further pull in the clamping pin into the central opening and si- multaneously the work piece carrier towards the surface portion serving as a Z-direction stop member until the flat bottom surface of the work piece carrier rests on the surface portion of the clamping chuck serving as a Z-direction stop member.
