Abstract: An abrasive/water jet cutting apparatus has a frame, a carriage movably supported for movement over a work table on the frame, and a water jet cutting head on the carriage. A main storage container for abrasive is provided and an intermediate storage container for abrasive is supported on the carriage. A connecting arm has a pivotal connection at its one end to the frame and a pivotal connection at its other end to the carriage. The arm also has a pivotal connection intermediate its length so that it pivots about the pivotal connections during movement of the carriage. A suction line from the main storage container extends along the connecting arm to the intermediate storage container to supply abrasive thereto, and a high pressure line extending from a high pressure fluid source extends along the connecting arm to the cutting head. The high pressure line is resiliently deflectable at the pivotal connections about which it extends, and the vacuum line is resiliently deflectable.
