Water jet cutting technology, which is originally called high-pressure water jet cutting technology, originated in the United States, has developed rapidly in China, and its innovation is relatively high. Used in aerospace military industry. Because the cold cutting will not change the physical and chemical properties of materials, it is popular. After continuous improvement of the technology, pomegranate sand was mixed in high-pressure water, which greatly improved the cutting speed and thickness of the water knife. Now water jet has been widely used in ceramics, stone, glass, metal, composite materials and many other industries. At present, the pressure of water jet has reached 420MPa in China. Some technology companies have improved the three-axis, four axis water jet, five axis water jet also tends to mature.

Compared with plasma cutting, EDM cutting, laser cutting and wire cutting, the advantages of high-pressure water jet cutting technology are particularly prominent, and there are incomparable places in other technologies.

Let's take high-pressure water jet cutting machine for example. High pressure water jet cutting is cold cutting. In the process of processing, there is no heat effect, and there is no thermal deformation phenomenon. Its narrow cutting seam can save materials, and the precision is particularly high. In addition to these advantages, high-pressure water jet cutting technology can not only be applied to the traditional processing industry, but also can be used for other processing equipment can not complete the material cutting, such as composite materials, paper, chemical fiber, thermal materials, glass, ceramics processing, etc., high-pressure water jet cutting can play a greater advantage.

In real life, many people simply think that laser cutting is faster than using high-pressure water jet cutting machine for high-pressure water jet cutting. However, many people ignore that laser cutting has great limitations in thickness. Laser cutting can only cut metal materials with thickness less than 16mm, in addition, it will produce a lot of heat at the cutting edge. High pressure water jet cutting can completely avoid these limitations. It can not only cut metal materials with a thickness of more than 30mm, but also cut materials with a thickness of 100mm without any difficulty, and will not cause any damage to the cutting object. Because of the above advantages, many people will voluntarily use high-pressure water jet cutting machine for high-pressure water jet cutting instead of laser cutting.
