ABSTRACT:
The present invention provides an apparatus and method for treating jet engine components with high pressure water. The apparatus of the present invention broadly consists of a generally enclosed room-size chamber, a water delivery means, including a nozzle body having multiple water emitting orifices, a support frame and gantry for supporting the water delivery means whereby the water delivery means is movable along multiple axes, a workpiece supporting turntable and a computer or microprocessor for controlling the operational parameters of the apparatus. Additionally, the present invention provides a method for using the apparatus to blast jet engine components with high pressure water without added chemical or particulate abrasives, the operational parameters of the apparatus being selected from a range of such parameters. The water is directed against the component under very high pressure to remove coatings or deposits or to machine the component.
