Patent ID: 8375580

Claim:
A method for manufacturing cams for composite camshafts comprising the steps of: hot-forming a cam such that a cam outside contour is produced and a cam bore is punched, and axially and radially calibrating the cam, wherein the calibration comprises the steps of: inserting the cam into an undivided mould; inserting an arbor into the cam bore; and axially shortening the cam between a lower die that is situated between the mould and the arbor and on which the cam lies with a first end face and an upper die that is guided between the mould and the arbor and acts upon the second end face of the cam; wherein the axial shortening of the cam results in a calibration of both the cam outside contour and the cam bore such that a correction of the cam before and the cam outside contour relative to one another is produced; wherein said undivided mould defines the calibrated cam outside contour; and wherein said arbor defines the calibrated cam bore.
