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.
