摘要: A machine tool (1) driven by linear motors (8, 9, 10) along a plurality of axes (X, Y, Z) and unusually robust and rigid, comprises a bed (2) which defines at least a first axis (X), at least one column (3) operably connected and supported only at one of its ends (7) by said bed (2), for its guided movement along the first axis (X), said at least one column (3) extending away from the bed (2) to define a second axis (Y), at least one saddle mount (4), for its guided movement along a third axis (Z) and supporting a spindle (6) for the movement of a tool, wherein said at least one column (3) comprises a portal structure having a first shoulder (11) opposed to a second shoulder (12) such as to define a window (13) within which the saddle mount (4) is arranged, and wherein, between said opposed shoulders (11, 12) and the saddle mount (4), linear motors (9) are interposed such as to move the saddle mount (4) along said second axis (Y), producing an effect of attraction of the shoulders (11, 12) towards the saddle mount (4).
