Abstract
The invention relates to process for chase-forming, in particular the chasing, cylindrical flow-turning and projection flow-turning of workpieces and a device therefor, whereby a workpiece is clamped in a clamping device, rotated and shaped by at least one chasing tool. In particular, a laser beam device is provided, said device applying a laser beam to the workpiece which is thus heated up in order to lower the yield stress and improve shaping capability, and to perform a heat treatment.
