Fluid jet cutting and shaping system and method of using

Abstract

Fluid jet cutting system having an X-Y axis support table adjustable in both the X and Y-axis direction and frame structures that overhang a support platform assembly. The frame structures include overlapping central openings positioned above an opening defined by the platform assembly. A driving system such as a linear motor system shifts the support table. A Z-axis holder is provided for supporting a nozzle head assembly in a central area of the opening defined by the platform assembly. The nozzle head assembly has a main body fixed in position or limited to Z-axis movement with or without fourth and fifth axis rotation capability (i.e., the nozzle head assembly is precluded from movement linearly in the X and Y-axis directions). Workpieces are supported by rails or the like within the open area. The nozzle head assembly directly receives abrasive though a plurality of abrasive ports which receive branch tubes of a multi-branch abrasive feed assembly. The fluid jet energy is conserved by the abrasive flow arrangement, the avoidance of lengthy tubing, the providing of uninterrupted high pressure fluid conduits, and a gas forced abrasive particle stream when particles are utilized. Avoiding the nozzle head assembly shift along an X-Y plane allows for a stationary catcher tank which can be rolled into and out of position on a roller carriage. The system includes a filter internally positioned within an attenuator and bellville seal/return members provided in respective chambers of a dual action intensifier.
