Taking metal cutting as an example, various processing methods coexist, including cutting tool, laser, flame cutting (plasma cutting), EDM, wire cutting and water cutting. All kinds of cutting methods have their own advantages, but also have certain limitations, and each occupies a part of the market. But in many cutting methods, as long as the water cutting belongs to the cold cutting, the kinetic energy of abrasive water jet is directly applied to stop cutting the metal to achieve the cutting purpose. There is no chemical change in the cutting process. It has the advantages of no impact on the physical and chemical properties of the cutting material, no thermal deformation, narrow cutting seam, high precision, bright cutting surface, clean and pollution-free. It can process traditional processing and other processing Methods can not or difficult to process information, such as glass, ceramics, composite information, reflective information, chemical fiber, thermal sensitive information. With the further understanding of water cutting technology, the market gradually realized the common advantages of water cutting technology in metal cutting industry. Taking laser cutting as an example, in the thin plate cutting, laser is better than water cutting in cutting speed, but in the metal cutting of more than 16mm, the investment is high, and there is still a certain heat affected zone around the laser cutting data. The thickness of the metal cutting data can reach 30mm-100mm, and has no effect on the data There is no limit on cutting data. Combined with these factors, many users who used to choose laser or other wrist cutting tools choose water cutting machines instead.
At present, the CNC platform of "water jet" mostly adopts the fine transmission technology of ball screw and rolling linear guide rail, and the control accuracy is within + 0.02mm. At the same time, the focusing performance of the nozzle and cutting head with sand water jet and the technology of short-lived nozzle data are broken, which is coordinated with the continuous and stable work of 400MPa high-power ultra-high pressure system, and the full-automatic sand supply and control, and the start and stop control of high-pressure water With the cooperation of the system, the "water knife" can cut continuously and process automatically for 24 hours.
"Water knife cutting machine" has powerful computer-aided design and control functions, especially in the "corner and sharp corner" cutting automatic deceleration, in order to reduce the impact of tail flick in cutting, making the cutting surface bright and sophisticated. In addition, the "water knife" cutting has the characteristics of "grinding", which makes the "water knife" in cutting quality and efficiency have great changes and progress, and can be directly used It is used for forming and cutting metal parts.
