Development trend of Waterjet cutting Technology
Dec 19, 2018

          Waterjet cutting characteristics, for example, in metal cutting, various processing methods coexist, including cutting tools, laser, flame cutting (plasma cutting), electric spark, wire cutting, waterjet cutting and other processing methods. All kinds of cutting methods have their own advantages, and they all have certain limitations, each occupying a part of the market. However, among the many cutting methods, only waterjet cutting is a cold cutting. The kinetic energy of the abrasive water jet is directly used to cut the metal to achieve the cutting purpose. There is no chemical change during the cutting process, and there is no influence on the physical and chemical properties of the cutting material. Hot deformation, narrow slit, high precision, smooth surface, clean and pollution-free, can process materials that cannot be processed or processed by traditional processing and other processing methods, such as glass, ceramics, composite materials, reflective materials, chemical fiber, heat sensitive Materials, etc.


          As people's understanding of waterjet cutting technology deepens, they gradually realize the unique reference information network advantage of water cutting technology in the metal cutting industry. Taking laser cutting as an example, the laser is better than the water cutting in the cutting speed of the thin plate cutting. However, the laser cutting in the metal cutting of 16 mm or more is expensive and the surrounding of the laser cutting material is still high. There is a certain heat affected zone. Waterjet cutting metal materials generally have a thickness of 30 to 100 mm or more, and have no effect on the material, and the waterjet has no limitation on the cutting material. Combining these factors, many users who originally chose laser or other cutting methods turned to water cutting machines.


         At present, the numerical control platform of "waterjet" mostly adopts the precision transmission technology of ball screw and rolling linear guide. The control precision is within 0.05mm, and the focusing performance of the nozzle and cutting head with sand water jet and the long-life nozzle material The technical breakthrough, combined with the continuous and stable work of the 380-400mpa high-power ultra-high pressure system, can be fully automatic sand supply and sand control and high-pressure water start and stop control system, so that the "waterjet" can automatically cut continuously in 24 hours.


        "Waterjet" has powerful computer-aided design and control functions, especially in the "corner and sharp" cutting, to reduce the impact of the tail in the cutting, making the cutting surface smooth and smooth, plus "waterjet" cutting With the characteristics of "grinding", the "waterjet" has been greatly changed and improved in cutting quality and efficiency, and can be directly used for forming and cutting of metal parts.
