PATTERN-CUTTING MECHANISM OF APPARATUS FOR CUTTING MATERIALS BY SUPER-HIGH PRESSURE LIQUID JET

摘要

A cutting portal for an ultra-high-pressure fluid jet cutting system separates the longitudinal and transverse motion of the cutting head support. The portal includes two parallel plates with lightweight, honeycomb composite material between them. The cutting portal is moved transversely of its length longitudinally of the cutting table. A guide rail for the cutting head support is supported in the honeycomb material and extends along the length of the cutting portal, transversely to the motion of the cutting portal. Spaced apart bearing shafts are supported by bearing shells in the honeycomb material. A driven belt passes around the shafts and moves the cutting head support along the guide rail, which provides motion of the cutting jet in the transverse direction of the cutting table.
