Waterjet cutting accuracy and cutting speed control

Waterjet cutting accuracy and cutting speed control

The water jet is processed by ultra-high pressure technology. The water jet can be used to cut soft base materials, normal tap water is pressurized to 250-400 Mpa pressure, and then sprayed through a gemstone nozzle with an inner hole diameter of 0.15-0.35 mm. A high-speed jet with a speed of about 800-1000m/s can be formed. Abrasives are generally added on the market to improve the cutting ability of water cutting, such as the combination of garnet, water and garnet, which can form a huge penetration.

Water jets can be used to cut two-dimensional shapes, including metals, ceramics, plastics, stone, glass, and carbon fiber, and can even produce complex and detailed shapes. Compared with other cutting methods, the water jet can remove the material without heating, so that the debris of the material is washed away by the cutting water, which improves the cutting efficiency.

The cutting speed and accuracy of the water jet are two closely related parameters. Only when the cutting accuracy of the water jet is satisfied, can the speed be further pursued. Due to the short cutting platform, it is difficult to judge with the naked eye whether the top speed can be reached. In this case, we can simulate the work using the software that comes with the servo drive of the cutting machine. See if the motor speed is the highest.

In general, when testing the waterjet cutting speed, the acceleration and deceleration of the waterjet can be increased without actually cutting; each axis can be tested individually or simultaneously. In addition, the construction industry generally requires the water jet cutting accuracy to be less than (+0.5mm), the automotive reflector to be less than (+0.Olmm), and the lower the cutting requirements for steel plate processing, the better.
