A device for the centered clamping of an annular workpiece or workpiece stack formed of a plurality of annular workpieces, to hold the same in position for the machining of the inner faces thereof, includes first and second axially aligned clamping rings for engaging opposite, radially extending end faces of a workpiece or workpiece stack positioned in a space between the clamping rings; a centering cylinder surrounding the space and having a lead-in chamfer at one edge thereof; and a clamping arrangement for moving the two clamping rings relative to one another. The clamping arrangement comprises a power device actuatable in a clamping direction; a force-transmitting arrangement extending exclusively externally of the centering cylinder and coupling the clamping rings to one another and to the power device; and an axial stop for abutting and arresting the second clamping ring when urged in the clamping direction by the power device with the intermediary of the force-transmitting arrangement, the first clamping ring and the workpiece or workpiece stack for clamping the latter between the first and second clamping rings.
