Abstract
A method of clamping rotationally symmetrical workpieces for their circumferences to be ground, whereby the radial positioning, the clamping and the axial positioning of the workpiece are effected independently of one another, so that the positioning operation is not affected by the clamping operation and is accurately maintained. In addition, a clamping device for implementing the method includes a first member which radially positions the workpiece, a second member which clamps the workpiece for transferring torque, and a third member which axially positions the workpiece.
