Introduction to the correct use of sand water knife

The basic technology of ultra high pressure water knife is both simple and extremely complex.When water is pressurized to a very high pressure of 380Mpa to 430Mpa and passes through a small opening of a special nozzle (with a diameter of 1.0mm to 0.5mm), it can produce a water arrow reaching nearly 1000 meters per second (about three times the speed of sound). This high-speed water arrow can cut a variety of soft materials including food, paper, diapers, rubber and foam.This cutting is called pure water cutting.When a small amount of sand, such as pomegranate sand, is added to the water jet and mixed with it, the resulting sand-adding water jet can actually cut any hard material including metal, composite materials, stone and glass.~

This is a very unique and advanced cold cutting, and it can be controlled by computer program.In the increasingly competitive water cutting industry, many users fail to use pomegranate sand properly, the main reasons are as follows:

First, they may not have the awareness and philosophy to realize the importance of pomegranate sand in the whole cutting process.

Second, there may be a cost associated with using pomegranate sand.

Actually garnet sand costs only a small part of the cost of the project, if not the correct use of high-quality garnet in the problems appeared in the process of cutting, led to the suspension of cutting, cutting failure, damage (including time, money, products, equipment) will spend far more than it takes to buy quality garnet.

High quality garnet can not only meet the cutting needs, but also to avoid problems.Using pomegranate sand reasonably can make the water knife play better performance.The stable cutting performance of pomegranate sand will not block the sand pipe, maintain continuous and uninterrupted production work, to achieve the best efficiency and the lowest production cost.

Therefore, the proper use of high-quality pomegranate sand is the key to the water cutting process. Someone even made this analogy: "If the water knife is the skeleton of the water cutting, the pomegranate sand abrasive is the blood of the water cutting."
