The structure of the water jet is very simple. It only needs ordinary water and a high pressure intensifier pump. With this device, it can pressurize ordinary water up to 4000bar, and then spray it through a small nozzle to form cutting force.
It is this seemingly simple water jet that can do various surface treatments and cut various non-metallic substances, including paper, glass, fiber, sponge and so on. This is the ability of the water jet. If you want to cut some metals and hard materials, such as stone, glass, ceramics, tiles, etc., you only need to add appropriate sand on this basis.
The use of sand greatly improves the cutting ability of the water jet. This high-speed abrasive water jet can cut almost any material. In addition, the nozzle of the water jet is made of cemented carbide, sapphire and other materials, and its nozzle diameter is only 0.05mm, and the inner wall of the hole is smooth and flat, which can withstand 1700mpa pressure, so the high-pressure water jet can cut materials like a knife.
There is also water jet that adds some long-chain polymers, such as polyethylene oxide, to the water to increase the viscosity of the water, so as to improve the processing accuracy. Even if the cutting width is only 0.1-0.8mm, they can process parts with complex profiles.
When the water jet is used for cutting various stone and ceramic materials, and the cut materials are combined into a puzzle, it is called water jet mosaic, which is also a very common way in water jet applications.
