Waterjets

This technology involves a cold cutting process that uses pure supersonic water, or water and abrasive, to erode material. An ultrahigh-pressure pump generates a stream of water with extreme pressure that is converted into velocity via a tiny jewel orifice, creating a supersonic stream as small as a human hair to cut soft materials. Garnet can be added to this supersonic stream to greatly increase cutting power. Water and garnet can exit the cutting head at nearly four times the speed of sound, making the waterjet capable of cutting steel over one foot thick. Pure and abrasive waterjet technologies combined can cut virtually any material, any shape, at any thickness. Pure waterjet cuts soft materials like gasket, foam, plastic, paper, disposable diapers, insulation, cement board, automotive interiors, carpet, food. Abrasive waterjet can cut hard materials like metal, ceramic, stone, glass and composites.
