Abstract
A clamping system includes a workpiece machining head (1) having a coupling member (40), a mating coupling piece (90) and a drawbolt (30), a pressure-medium actuated clamping device (10, 15, 17, 19, 20) for the drawbolt (30) being provided on the workpiece machining head (1), the coupling member (40) having an axial reference axis (Z-axis) (50) and reference parts (42, 44, 46; 41, 43, 45), which are arranged at its end in a plane that is perpendicular to the reference axis and define a Z-reference for a first reference system, and the mating coupling piece (90) having at its end face mating reference parts (91, 93, 98; 95, 97, 99) for the first reference system. In order to make the clamping system universally usable, provision is made for the coupling member (40) to be surrounded by a coupling part (60), whose axis extends parallel to the reference axis (50) and which has reference elements (61, 63, 65, 67; 72, 74, 76, 78) which define a Z'-reference and are assigned to a second reference system.
