A machine for processing large workpieces, particularly a hydraulic press for working on large metal sheets, comprises external equipment for rigidly supporting and guiding the workpiece. The handling equipment is provided with means which permit the workpiece, together with part of the handling equipment, to carry out movements induced by the reactional forces generated in the workpiece by the tools of the machine. Those forces are held within predetermined limits, whereby the handling equipment is protected against damage but still capable accurately to position the workpiece relative to the tools before each processing step carried out by the tools.
