[0002] The water jet technology originated in the United States and was developed by Smith & Nephew. The water jet is a multi-purpose, modern cutting technology with perfect performance. During the cutting process, it can achieve the characteristics of no thermal deformation, smooth incision, no dust and pollution, and reduced material waste.

[0003] It is a technology that uses high-pressure water jets to cut materials under computer control. It can cut materials of any texture and will not produce heat during the processing. The advantages of waterjets are their non-thermal cutting properties, high precision and multi-material cutting capabilities, making them ideal for many special fields, such as aerospace, medical device manufacturing, electronics, nanotechnology, construction, art and sculpture. In practical applications, waterjets can be used to cut a variety of materials, such as stone, metal, ceramics, etc., and can also be used to make artworks, decorations, etc. With the continuous development of technology, the application scope of waterjets will continue to expand. Existing waterjets can be classified according to different standards:

[0004] According to the sand adding conditions: it can be divided into two methods: sandless water jet cutting and sand added water jet cutting.

[0005] By equipment: divided into large water jet cutting machine, small water jet cutting machine, three-dimensional water jet cutting machine, dynamic water jet cutting machine. By pressure: divided into high pressure type and low pressure type, generally with 100MPa as the boundary. Above 100MPa is high pressure type, below 100MPa is low pressure type. And above 200MPa is ultra-high pressure type.

[0006] According to the technical principle: it is divided into pre-mixing type and post-mixing type.

[0007] According to safety cutting: it is divided into safety cutting and non-safety cutting. The difference mainly lies in the water pressure. Low-pressure water cutting below 100MPa can be used in special industries such as hazardous chemicals, petroleum, coal mines, and dangerous goods processing.

[0008] According to the mechanical structure: divided into cantilever type and gantry type.
