How to control the precision and cutting speed of waterjet?The waterjet cutting process is completed by ultra-high pressure technology, just press the ordinary tap water to 250-400Mpa pressure, and then spray through the gemstone nozzle with an inner hole diameter of about 0.15-0.35mm *, you can form a speed of about 800 -1000m / s high-speed jet, this is a water jet that can be used to cut soft base materials.
Under normal circumstances, when testing the waterjet cutting speed, there is no need for solid cutting to increase the acceleration and deceleration; each axis can be tested separately or simultaneously. In addition, the precision of waterjet cutting is generally required to be less than ± 0.5mm for the construction industry; but it is required to be less than ± 0.01mm for automotive mirrors; the lower the cutting requirements for steel plate processing it is good.
At present, the cutting accuracy that various machine manufacturers can provide is generally less than ± 0.2mm, but this can not be seen only in the introduction of the product manual. During the acceptance, there should be a complete set of procedures for testing the cutting accuracy. The accuracy shall prevail.
