ABSTRACT:
The invention relates to a machine tool having a gantry that is movable along an X axis and having a vertical spindle supported by the cross-member of the gantry. The cross-member comprises two beams that are spaced apart in the X axis direction and that have facing inside faces. Two carriages are mounted to slide on said facing faces, on opposite sides of a vertically movable cursor-carrier. The tool-carrier spindle is carried by a cursor mounted to slide on the bottom face of the cursor-carrier and movable along the X axis. Movements of the carriages, of the cursor-carrier and of cursor are under numerical control. The tool-carrier spindle can move in the X axis direction without it being necessary to move the gantry.
