Abstract
A semifinished hardenable-steel workpiece is introduced into a gap between a punch tool and a complementary die tool while the workpiece is heated above the ACpoint. Then one of the tools is vertically shifted toward the other tool so as to deform the workpiece to a predetermined shape. Subsequently the workpiece is gripped between the punch and the die tools while cooling at least one of the tools to press-quench the workpiece. Finally, but before the press-quenching is completed, an edge is cut off the still hot workpiece by relatively shifting an upper die and a lower die vertically past each other.
