  • Patent number: 5854460
    Abstract: A gantry assembly and appurtenances therefor for a linear motor driven laser cutting machine. The gantry box is made of honey comb construction characterized by high strength, light weigh, high stiffness to weight ratio and vibration absorption. The gantry box is supported at each of its ends on a linear motor driven carriage by a torsion plate. The torsion plates are exteriorly flanked by protective panels which support a light weight cover for the upper part of the gantry assembly. The beam end of the gantry box is additionally attached to its gantry carriage by a snubber pin-snubber bushing assembly and by a gantry pin-carriage pin-link assembly. These last two assemblies, together with the torsion plates and gantry carriages, limit or restrain certain movements of the gantry box. The laser cutting machine is controlled by a high performance multi-axis motion controller.
