Waterjet cutting is realized by waterjet with great kinetic energy and high speed. It belongs to high energy beam category as well as laser, ionic beam, electron beam. Among them HP waterjet cutting is the only processing technology which is made in cold state. As a high and new technology, to some extent, it is a revolution in cutting field. Currently HP waterjet cutting is mainly applied in below areas. Application in metallic material cutting1) To cut the metallic materials used for architectural decoration, such as stainless steel. 2) To make and cut the crust of machine equipments 3) To cut all kinds of metallic spare parts Waterjet system offers several important advantages over other forms of cutting. -No thermal or chemical deformation -Excellent edge quality and no need of secondary processing -An environmentally clean process creating no toxic fumes or airborne dust -To cut very quickly and precisely -Saving in material Waterjet cutting is widely used in modern manufacturing industry, especially in engineering plant & manufacturing sector. It improves production efficiency and quality greatly. Application in glass cutting1) To cut the glass of household electrical appliances 2) To cut glass used in shower room 3) To cut glass for architectural decoration, craftwork and auto. It is the only fit way to use waterjet to cut anomalous shapes of glass. It solves the problems of making characters and hollowed-out work with glass. That is to say, all difficulties is readily solved by waterjet cutting. For instance, to make large glass screen, glass curtain wall, all kinds of electrical appliance panels and glass wares. Application in processing tiles, stones and other building materials.Water cutter is applied in this field much earlier. Currently, the overwhelming majority in this area use it. They focus on artistic matching. At present, tile matching and stone matching have expanded all over the world. It is the best way to use water cutter to process tiles. It largely improved production efficiency and processing precision. It achieved an epochal progress of tiles further processing, as it said good bye to the traditional ways of manual grinding and polishing. Presently waterjet cutting is mainly used to make all kinds of complex tile or marble matching. Application in composites, bulletproof material, soft material and others1) With robot arm to cut automotive interior components 2) To cut foam, sponge, paper, rubber, etc. 3) To cut nylon, carpet, etc. It is the latest processing method to use waterjet for soft materials, such as rubber, plastic, carpet and so on. It not only can improve processing efficiency and precision but also reduce the cost. It is a supplement to traditional processing ways.
