Abstract: A method for completely machining at least unprocessed centric journals (10) and crankpin journals (11), and the respective flat shoulders (9, 10) thereof surrounding the journals, of flanged or cast blanks of a crankshaft first includes turning the flat shoulders (9) associated with the journals (10). Then, the centric journals (10) are roughly ground without the flat shoulders (9) thereof and the crankpin journals (11) are roughly ground together with the flat shoulders (12) thereof. After the journals (10, 11) have been roughly ground, an allowance remains that is smaller than an allowance required for common finish grinding of journals and flat shoulders. The rough grinding is followed by the finish grinding of the centric journals (10) and the crankpin journals (11) from the smaller allowance (23) remaining due to the rough grinding to the final dimension.

The post-centering balance meter is configured to measure the shape of a post-centering crankshaft blank on the basis of a pair of center holes. Additionally, the post-centering balance meter is configured to set a principal axis of inertia on the basis of the shape of the post-centering crankshaft blank and generate center hole positional information for correction that indicates intersections between the principal axis of inertia and the both end surfaces of the post-centering crankshaft blank. The center hole boring device is configured to bore a pair of center holes on both end surfaces of another crankshaft blank to be loaded next on the basis of the center hole positional information for correction.

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.
