Why you should choose water jet cutting services

October 08, 2020

A water jet cutter or a waterjet is an industrial tool that is able to cut through a wide variety of materials using an extremely high-pressure jet of water. Water jet cutting services are used to cut various materials that would otherwise have a difficultly with other procedures. Sometimes, the water has an abrasive added to it to help cutting hard materials like metal or granite.


The process is generally used to fabricate various parts of machines, especially when the materials being cut are sensitive to heat or high temperatures generated by other cutting methods. Waterjet cutting is used in various industries such as mining and aerospace for cutting, shaping and reaming.


When you opt for a water jet cutting service, here is what takes place.


Water is passed through a high-pressure pump and into a waterjet. The waterjet has a nozzle built to withstand the force and pressure exerted by the stream of water. This jet of water can measure up to Mach 3 or around 2,500 ft/s (760 m/s) which is approximately the same speed at which certain fighter jet planes fly. If the task requires an abrasive waterjet, then the process is slightly different. Just before the water escapes the nozzle, abrasive elements such as garnet and aluminium oxide are fed into the nozzle through an abrasive inlet. This abrasive then mixes with the water to create an even more effective cutting tool.


Benefits of using a water jet cutting service include an accuracy of down to 0.005 inches and repeatability down to 0.001 inches. Using a waterjet also reduces the amount of scrap metal left over after cutting due to its relatively low kerf. Since there is no heat generated when using a waterjet, it is the process of choice when dealing with heat-sensitive materials. This allows for highly accurate, sharp and waste-less cutting.
