A method of clamping a rotationally symmetrical body ( 10 ) for the purpose of machining, in which method the body ( 10 ), with its first side ( 12 ), is pulled by means of a tensile force (F 1 ), which acts in extension of the rotation axis ( 19, 19 ') of the body ( 10 ) on the first side ( 12 ) of the body ( 10 ), against a supporting element ( 72 ) having a centering effect. A device for clamping a rotationally symmetrical body ( 10 ) for the purpose of machining, which device comprises a supporting element ( 72 ), against which the body ( 10 ) can be pulled, and a tie rod ( 64 ) which can act on and pull the body ( 10 ), to be clamped, axially and concentrically to the rotation axis ( 19, 19 ') of the latter. The mounting of the tie rod ( 64 ) is designed in such a way that the tie rod ( 64 ) is axially guided with radial clearance ( 66 ) for the axial pulling movement. The tensile force (F 1 ) of the tie rod ( 64 ) is preferably adjustable. A rotationally symmetrical body ( 10 ), in particular a rotor, which, on a first side ( 12 ), has a coupling unit ( 18 ), which is concentric with its rotation axis ( 19 ), and a bearing region ( 22 ) having at least three bearing surfaces ( 24 ) arranged concentrically to the rotation axis ( 19 ). |
