摘要： A press for pressing workpieces can have a) at least two pressing tools and at least one slide that performs working movements with an associated working stroke, b) at least one hydraulic slide drive unit for the slide, which separates a first sub-chamber and a second sub-chamber of a working chamber, and c) at least one slide position measurement device. Additionally, the press can include d) at least one medium reservoir, e) at least one first hydraulic delivery device connected to the first sub-chamber and to the medium reservoir, and f) at least one second hydraulic delivery device. The press can further include g) at least one controllable hydraulic valve, and h) a control device that checks the volumetric flows, pressures, and flow direction of hydraulic medium as a function of the measured slide position and stored or desired movement profiles of the slide and/or of input information from users.
