An automatic open-structure machine tool has an upright (3) which moves along a track (2) (axis X) fixed to a base (1), the upright being integral with a projecting crosspiece (4) along which moves (axis Y) the support (5) of a sleeve (6) which moves along an axis orthogonal to the preceding ones (axis Z). An additional structure (8) designed to be located at the open side of the machine tool is, fitted with a connector system (9) which slides along the structure, such connector system being designed for connection to the free end of the crosspiece, so as to make the open-structure into a gantry machine.
