    • 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.
    • 本发明涉及一种用于在工件(13)上基本上旋转对称的底切轮廓产生的方法,其可以例如通过锻造或铸造来生产,所述工件具有至少一个待加工的子部分(14),其具有基本对称的初始 轮廓。 工件(13)被不加工的端部支撑在凹部(11)中,并且当在所述凹部(11)中时,待加工的工件的子部分(14)抵靠工具 (12)。 工具(12)相对于待加工的工件(13)的子部分(14)以恒定的或可变的速度旋转。 通过在轴向压力下的机械加工,在工件(13)的子部分(14)上产生底切轮廓。
