A fluid jet cutting system that includes an X-Y axis support table that is adjustable in both the X and Y-axis direction and has frame structures that overhang a centralized 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 that is fixed in position or limited to Z-axis movement with or without fourth and fifth axis rotation capability. Workpieces are supported by rails or the like within the open area. The nozzle head assembly directly receives abrasive through a plurality of abrasive ports which directly 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. The avoidance of having 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 further includes a filter which is internally positioned within an attenuator and bellville seal/return members provided in respective chambers of a dual action intensifier.
