1. A method for balancing a workpiece, comprising
rotating the workpiece about an axis of rotation, wherein the workpiece comprises a balancing disk with a fully-round outer contour;
measuring the forces and/or torques and/or oscillations that result during the rotation of the workpiece from an unbalance of the workpiece; and
removing material of the balancing disk so as to reduce the unbalance and cause the balancing disk to have a non-round outer contour,
wherein the material is removed from the rotating workpiece during said measuring,
wherein the balancing disk is disposed on a shaft of the workpiece, wherein the balancing disk is distinct from and spaced apart from a functional portion of the workpiece along the shaft of the workpiece,
wherein a machining means for removing material of the balancing disk is of movable design, wherein removing material of the balancing disk comprises rough balancing where a first amount of material is removed from the balancing disk and fine balancing where a second amount of material is removed from the balancing disk, with the first amount of material being greater than the second amount of material, wherein the rough balancing and the fine balancing occur at different locations of the balancing disk.
