In our communication with waterjet cutting users, we often encounter such questions from customers. Generally speaking, customers who ask this question have two considerations. The first one is that the material you are cutting is relatively thin and fragile, and you are worried that the initial perforation pressure is too high and the material will be broken; the second is that some customers may want to use the machine for cleaning or engraving, and they are worried about damage due to excessive pressure. Material.
In fact, the small pressure of our waterjet cutting machine can reach about 20MPA, the working pressure value is generally between 20MPA and 420MPA, and the continuous working pressure is usually around 320-360MPA. Under this pressure value, it is basically cutting any material. Materials, such as stone, glass, metal etc.
Generally, relatively soft materials such as rubber, foam, etc. can use relatively low pressure, which can also reduce the wear of related high-pressure waterjet cutting parts; relatively hard materials can use relatively high pressure, such as metal, etc. The cutting speed can be adjusted by properly adjusting the amount of sand supplied.
