Working principle
The ultra-high pressure water jet cutting machine is to pass ordinary water through an ultra-high pressure pressurizer, pressurize the water to 3000bar, and then generate a water jet of about 3 times the speed of sound through a water nozzle with a channel diameter of 0.3mm, under the control of the computer. It can easily cut soft materials of any shape, such as paper, sponge, fiber, etc. If adding sand increases its cutting force, almost any material can be cut.

Features:
1. There is no restriction on the cutting direction, and various special-shaped processing can be completed;
2. The lateral force generated by the water jet on the workpiece is extremely small, which can reduce the setting time and save the cost of using fixtures;
3. Water jet processing will not produce thermal deformation, no secondary processing is required, and time and manufacturing costs can be saved;
4. Water jet processing has fast cutting speed, high efficiency, and low processing cost.

Advantage:
1. It can easily cut stainless steel plate or hard marble, granite, etc.
It is an ideal or only processing method for materials that are difficult to cut, such as aramid fibers, titanium alloys and other composite materials.
2. No cracks are produced when cutting, and it can cut materials with narrow gaps. Generally speaking, the incision of pure water cutting is about 0.1mm to 1.1mm, and the incision of sand cutting is about 0.8mm to 1.8mm. As the diameter of the inner hole of the sand nozzle expands, the incision becomes larger.
3. Can be cut in all directions, including various shapes, angles, or slopes;
4. No secondary processing such as edging is required, and flying dust can be reduced during the cutting process, improving the working environment.

The form of water cutting and the composition of the water cutting machine:
The form of water cutting is divided from water quality, including pure water cutting and abrasive cutting; from the pressure method, there are hydraulic pressure and mechanical pressure; from the machine tool structure, there are gantry type structures and cantilever type structure.
