ABSTRACT:
A liquid cutting head for removing material with a high velocity jet of working liquid supplied by an ultra-high pressure pump includes a nozzle having an outlet for forming and directing a thin high velocity stream of liquid to impact against a workpiece to remove material therefrom. A suction hood surrounds the nozzle having an edge adjacent the workpiece and a liquid curtain extends between the edge of the hood and the workpiece for entrapping and wetting workpiece material removed by the liquid stream for pick up by the suction hood.
