Process for compensating eccentricities and imbalances of rotating parts

Process for compensating eccentricities and/or imbalances of rotating parts to be connected, said rotating parts including one of a spindle of a turning machine, a clamping device, a clamping chuck, and a clamping sleeve on a first section and said rotating parts including one of a workpiece and a tool on a second section, which are received in the rotating part on the first section, wherein said rotating parts have holding surfaces which are provided with profiles coordinated with one another in pairs and which each have one of three and six wedges which rise over imaginary cylindrical reference surfaces radially toward the outside or toward the inside of the imaginary cylindrical reference surfaces and each then drops steeply back to the reference surfaces, and which are offset by equal angles in the circumferential direction and have a joining gap in a joining position, wherein the slope of the wedges is between 1:50 and 1:500, the process comprising the steps of

• determining the angular position of eccentricity and/or the imbalance of respective rotating parts of the first and second section to be connected,
• joining the rotating parts in such a mutually angular position that, while reaching an engagement of the coordinated profiles of the holding surfaces, the eccentricities or unbalanced masses of the respective rotating parts to be connected being substantially diametrically opposite with respect to the axis of rotation of the rotating parts,
• subsequently, twisting the rotating parts one against the other in a direction of more frictional engagement of the coordinated profiles of the holding surfaces up to such a mutual angular position of the respective rotating parts, that the determined eccentricities and/or imbalances are situated diametrically opposite one another with respect to the axis of rotation and into a position of an optimal compensation of the eccentricities or unbalanced masses.
