Abstract (en)
[origin: WO0016920A1] The invention relates to a method and a device for treating the surface of workpieces (12, 12', 12 ). According to said method the workpiece (12, 12', 12 ) is at least partly subjected to the action of a roll (16, 16', 16''', 74', 74 , 86', 86 ) which is at least partly provided with an outer profile (22, 22', 76, 76', 78, 78'), in such a way that the treated surface (14, 14', 14 ) of the workpiece (12, 12', 12 ) is subjected to internal compression stress and the areas of the workpiece (12, 12', 12 ) situated below the treated surface are subjected to internal tensile stress, in each case in the axial and tangential directions.
