Water jet cutting uses a stream of ultra high-pressure water (66,000 psi) and abrasive particles to machine a large array of materials, including heat-sensitive, delicate or very hard. The resulting cut is both clean and accurate to a tolerance of 0.025mm. Unlike Laser or Plasma, the cold stream does not create hardened edges. Minor burr removal is generally the only post cutting clean up required. Many materials cut well using the water jet, among these are all metals and alloys, plastic, rubber, stone, ceramics and glass. Controlled head run rate, allows for cutting items up to 200mm thick. Vertical run out is almost non existent at optimum speed.
