A method for manufacturing cams for composite camshafts with the steps hot-forming a cam 11 such that a cam outside contour is produced and a cam bore 13 is punched and axially and radially calibrating the cam 11, wherein the calibration comprises the steps inserting the cam into an undivided mold 21 that defines the calibrated cam outside contour 12, inserting an arbor 23 into the cam bore 13 that defines the calibrated cam bore 13, and axially shortening the cam 11 between a lower die 22 that is situated between the mold 21 and the arbor 23 and on which the cam 11 lies with a first end face 14 and an upper die 25 that is guided between the mold 21 and the arbor 23 and acts upon the second end face 15 of the cam 11.
