Some advantages of abrasive water jet cutting

The utility model relates to a water jet which uses high-pressure water and granular abrasive (mainly garnet powder) to cut metal. In this way, water jet cutting is commonly used to create complex shapes on the X/Y axis of large flat metal plates or composite materials.

The addition of abrasive at the nozzle improves the cutting capability of the high PSI flow. It also allows the machine to be used only with water for positioning (or "fast") and then with an abrasive for cutting the workpiece.

Abrasive water jet cutting does not generate heat. This means it can be used to cut a variety of metals, as well as plastics and other materials, without melting, twisting or warping. The method can achieve a tolerance close to ±0.005" (0.127 mm) if required.

Metal waterjet cutting can also provide different cutting edge qualities depending on the end use of the cutting part. These differences are made by varying the speed of the process; Faster speeds can be used when the goal is to separate the material without regard to cutting edges. However, if parts are required to have tight tolerances and a smoother edge finish, slower cutting speeds are required. Thus, edge quality affects the cost of operations, with better quality edges taking longer to produce.
