The invention relates to a method for producing essentially rotationally symmetrical, undercut contours on workpieces ( 13 ) that can for example be produced by forging or casting, said workpieces having at least one sub-section ( 14 ) to be machined with an essentially symmetrical initial contour. The workpiece ( 13 ) is braced by the end that is not to be machined in a recess ( 11 ) and when in said recess ( 11 ) the sub-section ( 14 ) of the workpiece that is to be machined is placed against a tool ( 12 ). The tool ( 12 ) rotates with a constant or variable speed in relation to the sub-section ( 14 ) of the workpiece ( 13 ) that is to be machined. An undercut contour is thus produced on the sub-section ( 14 ) of the workpiece ( 13 ) by machining under the axial pressure. |
