Abstract
An abrasive liquid jet cutting system has a cutting head for directing a jet of ultra high pressure water and grit to a work piece. The jet cuts the work piece in a desired pattern to form a product. The liquid from the jet, grit, and particulate materials of the work piece are collected with a receiver located generally below the cutting head. Controls for both the cutting head and receiver are coordinated to move the receiver along with the cutting head so that the water and particulate materials are collected by receiver. The receiver has an upright tubular member provided with wear resistant sleeves and an upright central rod to absorb the impact forces of the water and particulate materials that move through the receiver. A drive means connected to the tubular body operates to continuously rotate the tubular body, sleeves and rod to distribute the wear around the sleeves and rod caused by the water, grit and particulate materials that impinge thereon.
