Masking fixture

Abstract:

A masking fixture includes a flexible cover and a rigid cover. The flexible cover is received within a cavity of the rigid cover. An air connector provides for a purge flow supply to be connected to the masking fixture via a port in fluid communication with an enclosure of the flexible cover. A method of treating a workpiece includes directing a pressurized fluid jet comprising an abrasive media entrained therein against an exterior surface of the workpiece and directing a purge flow through the workpiece while directing the pressurized fluid jet against the exterior surface.
