Abstract

A machine tool driven by linear motors along a plurality of axes, and unusually robust and rigid, comprises a bed which defines at least a first axis, at least one column operably connected and supported only at one of its ends by said bed, for its guided movement along the first axis, said at least one column extending away from the bed to define a second axis, at least one saddle mount operably connected and supported by the at least one column, for its guided movement along the second axis, at least one main saddle supported by the saddle mount, for its guided movement along a third axis and supporting a spindle for the movement of a tool, wherein said at least one column comprises a portal structure having a first shoulder opposed to a second shoulder such as to define a window within which the saddle mount is arranged, and wherein, between said opposed shoulders and the saddle mount, linear motors are interposed such as to move the saddle mount along said second axis, producing an effect of attraction of the shoulders towards the saddle mount.
