Abstract: A machine comprises on the one hand a mechanical working device, for working sheet material by pressing or stamping, and on the other hand a laser working device. The mechanical working device comprises a gantry hydraulic press comprising a frame, a table, an hydraulic press ram and a slide member. Several tools are stored in a storage device from which they are brought, on rails, up to the axis of the press by means of a jack. The laser working device comprises a resonator producing a laser beam which is conducted up to the axis of the press through a tube and by a reflecting mirror located on the axis of the slide member. When the laser cutting head is not in service it is retracted within one of the columns of the frame of the press, a jack producing the displacement of the cutting head. This equipment enables the carrying out, on a common axis of working, of either mechanical punching, cutting, folding, cumbering and pressing operations, or working by means of the laser.
