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. Each gantry
carriage is provided with a wiper-seal assembly and bellows mounting assembly
at each of its ends to prevent accumulation of foreign material between each
gantry mounted linear motor and its respective magnet track.
