The cutting speed of a water jet when cutting aluminum can vary depending on a number of factors including the thickness of the aluminum being cut, the power of the water jet, and the type of nozzle being used.The following data comes from the test of a booster pump with a pressure of 60Kpsi. When cutting an aluminum plate of about 5mm, the cutting speed with a 0.18mm waterjet orifice is about 15 inches per minute; if it is used with a 0.35mm waterjet orifice, the cutting speed is about 1 40 inches per minute or so. Of course, the test data is for reference only, because the abrasive supply and the pressure of the booster pump can be adjusted according to requirements..In general, water jets can cut through aluminum at speeds ranging from 100 inches per minute (IPM) for thinner aluminum sheets, up to 30 IPM for thicker aluminum plates. However, it’s important to note that the cutting speed can also be affected by the desired cutting quality, with more precise cuts requiring slower cutting speeds.It’s also worth noting that the cutting speed of a water jet can be adjusted during the cutting process to achieve the desired result. This can be particularly useful when cutting through thicker aluminum, as slower cutting speeds may be required to ensure a clean and accurate cut.
