There are three main uses of water cutting equipment: one is to cut non combustible materials, such as marble, ceramic tile, glass, cement products, which can not be processed by thermal cutting; the other is to cut combustible materials, such as steel plate, plastic, cloth, polyurethane, wood, leather, rubber, etc. these materials can also be processed by thermal cutting in the past, but they are easy to produce combustion zone and corrosion Burr, but water cutting will not produce combustion zone and burr, and the physical and mechanical properties of the cut materials will not change, which is also one of the advantages of water cutting; third, cutting flammable and explosive materials, such as ammunition and flammable and explosive environment, which can not be replaced by other processing methods.
Generally speaking, when laser, plasma, flame, wire cutting, sawing, milling and other processing methods can basically meet the requirements of processing technology, water cutting is not suitable. After all, the operation cost of water cutting is high. Nozzle, guide sleeve and high-pressure seal are imported consumables, and the price is expensive. But when you feel that the thickness of laser and plasma cutting is too thin, the burr is too big, and the heat affected zone is not good, you can consider water cutting; when you feel that the burr of flame cutting is too big, the roughness is too bad, and the heat affected zone is too big, you can consider water cutting; when you feel that the speed of wire cutting is too slow, and you can't cut non-conductive materials When you feel that the milling method has produced a lot of waste, resulting in a lot of waste, you can also consider using water cutting, because water cutting will not produce waste, but the whole piece of cutting, water cutting processing to separate the materials are mostly available; when you feel that the use of circular saw and band saw is too slow, and can not be non-linear cutting You can still consider water cutting; when you cut flammable and explosive materials or in flammable and explosive environment, you must also consider water cutting; when you do not want to produce toxic and by-products, do not need secondary processing, do not want to produce thermal effect or deformation or micro cracks, and want to produce good cutting quality and can cut small holes at the same time, you should also consider water cutting Cut. In a word, water cutting is a new way of cutting, but it is not good in some occasions, so we should make a specific analysis when choosing.
