Abstract:
A method for producing a workpiece from an elongated blank or intermediate product. The workpiece geometry is formed in a first method step, for example by forging the blank or intermediate product, a centering region for subsequent machining of the workpiece between centers being introduced in two oppositely situated sides of the workpiece with reference to the longitudinal axis thereof, and at least one of the centering regions having a desired deformation face. The workpiece is calibrated in a second method step, the desired deformation face being adapted in such a manner that the distance between the contact faces of the centering regions for the machining between centers being adjusted to a predetermined desired measurement. The invention also includes a corresponding workpiece with centering regions, at least one of which has at least one desired deformation face.
