ABSTRACT:
An aspect of the present invention relates to a method and a forming machine for working a workpiece, for example by deforming it or fixing it in another workpiece, in which the workpiece is fitted over a mandrel, at least a part of the mandrel is expanded so as to fix the workpiece, the workpiece and at least one tool, such as a forming roller, are rotated about an axis relative to each other and the workpiece is worked by means of said tool. The mandrel includes a stop adapted to engage the workpiece to obtain a desired axial position on the mandrel.
