摘要

A method for work hardening by rolling the surface of component parts, in particular of rotationally symmetrical or not - rotationally symmetrical rotating parts, which, in operation, a bending stress on bending or circulation, wherein the component to especially highly stressed areas, e.g. transition radii, by means of a roller with a profile adapted to the highly stressed point under the application of pressure is being rolled, characterised in that, on the component (10, 21) during the machining firmly rolling an external load (19, 20; 33, 34) is applied, in such a way that the component (10, 21) to be machined by work hardening by rolling on the points (14; 28, 29) under elastic prestress, in particular at the machining location under bending - and / or tensile pre-stress, is.
