A workpiece clamping system for a measuring machine, the workpiece clamping system comprising:

• a rotary table disposed about a workpiece rotation axis;
• a chuck associated with the rotary table, the chuck for receiving a workpiece concentrically;
• a rotary drive for driving the rotary table;
• an upper centering tip mounted on the measuring machine in the workpiece rotation axis and mounted vertically opposed to the rotary table;
• a lower centering tip mounted on the rotary table in addition to the chuck for accommodating a workpiece between the upper centering tip and the lower centering tip, the lower centering tip concentrically clamped in the chuck instead of the workpiece;
• and
• a conveying device for conveying the lower centering tip into and from a clamping position in the chuck;
• wherein the workpiece is not held in in the chuck;
• wherein the conveying device comprises conveying equipment for conveying the lower centering tip transversely relative to the workpiece rotation axis and along the workpiece rotation axis.
