A method of machining an oblong workpiece and a machine for performing the method Abstract A method of machining an oblong workpiece (18), which is placed substantially radially in a holding ring (1) and is deformed by cooperation with a roller (8) rotating in the holding ring. In connection with machining of a relatively large amount of material, the workpiece is caused to cooperate with a plurality of differently shaped areas (16) on the surface of the roller. The method is performed by means of a machine which comprises a rotating holding ring for substantially radial retention of the workpieces. The machine comprises a rotating roller which is placed inside the holding ring and is adapted to machine the radially inwardly directed end (17) of the workpieces. At least two differently shaped types of the machining areas (16 and 41) are provided along the surface of the roller, said areas being so disposed that the various types are present radially opposite a workpiece in a predetermined succession at least at the same time as the holding ring performs a correspond- ing number of entire revolutions.
