A device for the centered clamping, in a turning machine, of an annular workpiece or workpiece stack formed of a plurality of annular workpieces, has a centering cylinder; an arrangement for axially displacing the centering cylinder; 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; and a clamping arrangement for axially urging the two clamping rings to one another. The clamping arrangement includes a tensioning anchor extending within the work spindle of the turning machine. The device further has a releasable coupling for detachably connecting the tensioning anchor to the work spindle. The first clamping ring is secured to the tensioning anchor and the second clamping ring is fixedly attached to the work spindle.
