Cutting Accuracy and Cutting Speed Control of Water Cutter

The water cutter is machined by using ultra-high pressure technology. It only needs to press the ordinary tap water to 250-400 Mpa pressure, and then spray out through the jewel nozzle with inner hole diameter of about 0.15-0.35 mm. It can form a high-speed jet with speed of about 800-1000 m/s. This is the water cutter which can be used to cut soft-based materials. The market will generally increase abrasives to improve the cutting ability of water cutting, such as the combination of pomegranate sand, water and pomegranate sand, can form a huge penetration force.



Water knives can be used to cut two-dimensional shapes, including metals, ceramics, plastics, stones, glass and carbon fibers, and can even produce complex fine shapes. Compared with other cutting methods, water knife can remove material without heat, so that the debris of material can be washed away by cutting water, which improves the cutting efficiency.



The cutting speed and precision of water cutter are two closely related parameters. Only when the cutting accuracy of water cutter is satisfied, can the speed be further pursued. Because of the short cutting platform, it is difficult to judge whether the highest speed can be achieved by eyes. In this case, we can use the software simulation function of the servo driver of the cutting machine to check whether the speed of the motor is the highest.



Generally speaking, the acceleration and deceleration speed of water cutter can be improved without actual cutting when testing the cutting speed of water cutter; the axes can be tested separately or simultaneously. In addition, the accuracy of water knife cutting is generally required to be less than (+0.5mm) for construction industry, but less than (+0.Olmm) for automotive reflectors, and the lower the cutting requirement for steel plate processing, the better.
