In a press with an adjustable drive arrangement including, in addition to, a main drive, an adjustment drive for dynamically changing the press kinematics of the manually predetermined press angle-plunger stroke. Means are provided, whereby during a transforming process, the speed of a movable plunger of the tool part which engages the workpiece for the transformation thereof, is reduced, essentially to zero, for the moment of engagement between the plunger and the workpiece, so as to provide for a smooth impact force engagement between the plunger and the workpiece.
