Abstract
A crankshaft including narrow flat shoulders that are located next to a bearing pin at adjacent cheeks of the crankshaft. The narrow flat shoulders are machined by turning a rotary tool. In the process, the crankshaft that is clamped in a fixed manner and rotates about a rotation and clamping axis in which also the centric longitudinal axis formed by centric bearing pins of the crank shaft is located. As a result, the bearing pins rotate with a geometric axis thereof on a circular path about the rotation and clamping axis. The rotary tool tracks the moving bearing pins with regard to the vertical and lateral movement thereof in two movement directions that are perpendicular to each other. As a result, the rotary tool is in consistent lateral engagement with the flat shoulder of the bearing pin.
