Abstract
In a method for end processing a surface of a shaft-like workpiece, the following steps are performed in the following series, and the workpiece rotates about an axis of rotation: a) finishing the surface with a first finishing tool, b) machining the surface with a scoring tool, whereby the scoring tool produces at least one groove running in a circumferential direction, whereby the at least one groove produces 3 to 12 profiled gorges on a reference segment which reference segment has a length that is predetermined by a measuring method for roughness determination and which is extending on the surface parallel to the axis of rotation, each of said profiled gorges having a depth and width, whereby the ratio of the depth and width of each profiled gorge is greater than 2 and a distance between adjacent profiled gorges is substantially the same,c) machining the surface with the first finishing tool or a second finishing tool.
