Abstract

A method for producing a ready-for-use camshaft for controlling valves of an internal combustion engine may be directed towards camshafts that include a carrier shaft on which an end component, for example, a drive wheel, a phase adjuster, or a part of a phase adjuster, is arranged and cam elements that are attached in a positionally fixed manner to the carrier shaft. In some examples, the method comprises providing a carrier shaft and an end component, joining the end component to the carrier shaft, grinding at least the carrier shaft to form cam seats so as to establish readiness for use, introducing a surface profile into a first cam seat, providing a cam element with ready-for-use characteristics, seating the cam element on the cam seat with the surface profile, and repeating certain steps for additional cam elements.
