Abstract
The present invention provides a nozzle for high-pressure abrasive jet cutting systems that is particularly well-suited for fine-kerf cutting (e.g., 0.050 to 0.45 mm) using very fine abrasive particles (e.g., average particle size less than about 250 microns). The nozzle has a nozzle body defining an elongated channel extending along an axis. The elongated channel has a mixing stage and a focusing stage. The focusing stage has a focusing portion terminating in an outlet orifice for producing a high-pressure jet. The mixing stage has a sidewall defining a port in fluid communication with the elongated channel for admitting a low-pressure flow of a slurry comprising abrasive particles suspended in a fluid. The sidewall of the mixing stage is configured to have a relieved portion extending radially inwardly from the port toward the focusing stage. In certain embodiments, the taper is continuous from the port to the focusing stage.
