  • Patent number: 6345939
    Abstract: An apparatus for drilling structural shapes such as angles, I-beams and H-beams has sliders shiftable transversely to the beam along vertical and horizontal members of a frame through which the beam is passed. At least one of the sliders can have a rotatable carrier whose axis is perpendicular to the web or flange being drill and from which a respective drilling unit is radially offset. The longitudinal position of drilling is determined by the angular position of the carrier and any transverse offset is compensated by movement of the respective slider.

  • Patent number: 5839323
    Abstract: The invention relates to a moving gantry machine having uprights that are movable relative to each other. The uprights are interconnected by a cross-member made up of two cross-member elements suitable for being moved relative to each other in the limit of a given maximum offset .DELTA. in the displacement direction of the uprights. The displacement of the uprights is controlled by respective independent drive systems X.sub.1 and X.sub.2 under numerical control within the limit of said offset. A third drive system X.sub.3 is provided for displacement between the cross-member elements and is under numerical control with the condition the displacement distance of drive system X.sub.1 +the displacement distance of drive system X.sub.3 =the displacement distance of drive system X.sub.2.

  • Patent number: 4856178
    Abstract: A machine is accomplished comprising two pairs of operating heads in which each pair includes two identical operating heads essentially opposite to each other equipped with chucks rotating on horizontal axes having at one end a conical housing for receiving a tool.Each head can be moved longitudinally and vertically and the corresponding conical housing faces a central cavity.A machining tool or a clamping tool for holding the part to be machined can be inserted into each housing, so that one or two opposite chucks support the part while it is machined by the tool or by the tools inserted into one or more of the remaining chucks.

  • Patent number: 4215958
    Abstract: A drilling machine for working on longer workpieces, such as steel profiles having a fixed, non-variable frame. The machine includes a horizontal machine underpart arranged transversely to the longitudinal axis of the workpiece, two vertical side parts attached to the underpart ends and a horizontal upper beam attached on the side parts, and three drilling units each having a drilling spindle, a gear and a motor. The drilling units are shiftable in a plane parallel to the frame. The first drilling unit has a horizontal drilling spindle and is attached to a side part to the side of the workpiece; the second drilling unit has a second spindle arranged horizontally to the first drilling unit and on the opposing side of the workpiece; and, the third drilling unit has a vertical spindle and is attached to the upper beam. The second drilling unit has its horizontal drilling spindle on a horizontally driven carriage provided with lower wheels and upper wheels.
