Water cutting, also known as water jet, is a high-pressure water jet cutting technology, which is a machine that uses high-pressure water jets to cut. Under the control of the computer, the workpiece can be sculpted at will, and the material texture is less affected. Because of its easy operation, and high yield rate, water cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

　Waterjet has a wide range of applications, from metal materials to non-metallic materials, from natural materials to artificial materials, from food to daily necessities, basically can cut, and has the reputation of "universal cutting machine". The main application areas are: ceramic tiles, stone and other building materials processing. Glass product processing, such as cutting of glass parts in home appliances, architectural decoration, and craft glass. Cutting and cutting of sheet metal in the machinery industry. Signage, artistic pattern cutting, etc. in the advertising industry.

   Due to the effect of energy gradient, the deeper the cutting surface (the farther from the nozzle), the worse the cutting ability of cutting methods such as laser, gas plasma, and jet, so the formed cutting surface is often not perpendicular to the surface of the workpiece, which is called cutting Slope, which is an inherent defect of all cutting methods. Although the cutting slope can be partially reduced by increasing the cutting energy or reducing the cutting speed, there is still the problem of not being able to cut completely vertically. Therefore, the idea of a tiltable cutting head was proposed in 1997, and there are commercial products in the world. This is the most direct and effective way to solve the cutting slope and improve the accuracy. The principle is that by adding 2 more rotating shafts on the basis of the original three-axis platform, the cutter head can swing in any direction, and using the pre-set slope model in the system, through real-time calculation of the cutting trajectory, and then according to the cut The material and thickness of the workpiece are corrected, and the cutting head is constantly oscillated during the cutting process, so that the cut workpiece reaches a perfect non-slope state.
