A forging machine is described having at least one clamping head (6) for a work-piece (5) and having a rotational drive, which is controllable in dependence on the engagement of the forging tools (3), for the clamping head (6). To provide advantageous drive conditions, it is proposed that the rotational drive comprise at least one hydraulic motor (11), which is connected to a pump circuit (12), and which is connected to a hydraulic circuit (17), which is connected in parallel to the pump circuit (12), for the periodic supply and discharge of a predefined quantity of hydraulic medium in dependence on the stroke frequency and/or the stroke location of the forging tools (3).
