Abstract:
1. A fluid jet system comprising: an abrasive feed source configured to hold and output an abrasive paste; an orifice mount assembly comprising a mount body configured to sealingly receive a jewel orifice in a first region toward an upstream end of the mount body and a thin kerf mixing tube in a second region toward a downstream end of the mount body, such that a distance between a downstream exit end of a pressure-generating bore of the jewel orifice and an upstream entry end of a bore of the thin kerf mixing tube is less than approximately 0.5 inches, the mount body having a high-pressure fluid bore therethrough configured to communicate high-pressure fluid and having a longitudinal axis, and an abrasive bore open to at least one side of the mount body and configured to communicate the abrasive paste to at least a portion of the high-pressure fluid bore; and a first mixing area positioned upstream of the second region and comprising at least a portion of the high-pressure fluid bore and abrasive bore, the first mixing area being configured to allow the high-pressure fluid and the abrasive paste to mix before entering the thin kerf mixing tube.
