Water jet cutting is one of the only cutting technologies that does not heat the material. It delivers high precision cutting of any kind of flat material, whether hard or soft. Accordingly many sub-contractors have water jet cutting machines to satisfy the great variety of requirements expressed by their customers. Some manufacturers also use water jet cutting for specific applications. Alma has supported development of this technology ever since it first emerged roughly thirty years ago. Regardless of the type of use and the parts that are cut, the Almacam Cut software supports the specificities of water jet technology and is suitable for producing assemblies or cutting single parts.
Water jet cutting is a cold cutting process using a water jet projected at very high speed, sometimes combined with an abrasive additive. The water pressure is first increased from 4,000 to 6,500 bars and then the pressurized water is projected through a very small diameter orifice (0.08 to 0.4 mm in diameter). Depending on the pressure, the speed of the water jet can reach 1,200 metres/second. The water particles projected against the material’s surface cut it cleanly and precisely. To cut hard materials such as stone, marble, glass, metal, etc. the cutting power of the jet must be increased by adding an abrasive material.
Water jet cutting is recommended for all types of materials that cannot be cut using thermal processes. If no abrasive additive is used, water jet cutting is perfect for cutting thin sheets of soft materials such as plastic, foam, rubber, composites, wood, food products, etc.
Apart from the huge variety of materials that can be cut using this process, the main advantages of water jet cutting are that it is very clean, extremely precise (to within a tenth of a millimeter, the parts are not deformed, and the cutting is very quick. So water jet cutting combines quality, productivity and flexibility.
Almacam Cut is the ideal system to program your water jet cutting machines, particularly for cutting along profiles. It supports all the technological specificities of water jet cutting (relieving, speed decrease/increase, drilling on lead-ins/outs, etc.). Whether you are managing large-scale nesting or cutting single parts, Almacam Cut makes it easy to adjust cutting parameters to the wide variety of materials that can be cut using a water jet.
