Abstract
A rolling mill tool for smooth rolling slightly convexly or concavely curved surfaces of rotationally symmetric work pieces, such as bearing journals of crankshafts, has a milling roller with a slender and hence flexing configuration for conforming the shape of the milling roller to the curved shape of the work piece surface. Such a milling roller achieves a satisfactory rolling force or load distribution. The rolling force which is applied to the milling roller by a support roller is sufficient to flex the milling roller along its lengthwise axis to assume the shape of the contour of the work piece.
