A plurality of cylinder sections are welded together to form a milling cylinder, wherein, prior to welding, individual cylinder sections are machined in the region of their end edges to be welded, using at least one machining tool. Furthermore, the cylinder section to be machined is provided with inwardly oriented bracing means, wherein a temporary axle is fitted on the bracing means such that the temporary axle is oriented in the mid-axis of the cylinder section, and wherein the at least one machining tool is fastened to the temporary axle by means of a holder and the machining tool is rotated relative to the cylinder section about or with the temporary axle during the machining of the end edges.
