Forming machine and method for deforming a hollow workpiece

The invention relates to a forming machine at least provided with a clamping device for clamping a hollow workpiece having at least one open end and a first forming tool which can be placed into contact with the outer surface of the workpiece and with which the workpiece can be deformed. The clamping device can be rotated about a first axis and moved with respect to this first axis. Thus, the forming machine can be of relatively straightforward design and operate at high rotational speeds, even when a tool head equipped with a relatively large number of rollers is being used. The invention further pertains to a method wherein the clamping device can be moved with respect to the said first axis.
