According to the invention, a hardened workpiece surface (10) of a workpiece (1) is firstly machined and then rolled, and the machining process, which comprises the material removal process and the rolling process, takes place in the same clamping setup while the workpiece (1) rotates. Both the machining process and the rolling process produce intersecting machining marks (BS, BW), owing to the distance, which is measured in the axial direction (Tr) of the workpiece (1), between the tool (3) used for machining and the tool (12) used for rolling being oscillatingly changed during the machining process. 根据本发明，工件(1)的硬化工件表面(10)首先被加工，然后被轧制，并且包括材料去除过程的加工过程和轧制过程在所述工件(1)旋转的同时在同一夹紧装备中进行。由于在所述工件(1)的轴向方向(Tr)上测量的用于加工的工具(3)和用于轧制的工具(12)之间的距离在所述加工过程期间振荡变化，所以所述加工过程和所述轧制过程两者产生相交的加工轨迹(BS、BW)。
