Abstract (en)
[origin: WO2006063608A1] 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 of the workpiece (13) by machining under an axial pressure.
