Abrasive Waterjet Cutting
Abrasive waterjet cutting differs from pure water jet cutting in just a few ways. In pure waterjet cutting, the supersonic stream erodes the material.
In the abrasive waterjet cutting, the waterjet stream accelerates abrasive particles and those particles, not the water, erode the material.
The abrasive waterjet cutting machine is much more powerful than a pure waterjet and is capable of cutting hard materials such as metals, glass, stone, and composites: none of which can be cut with a pure waterjet.
Abrasive waterjet cutting machines using standard parameters can cut materials with hardness up to and slightly beyond aluminum oxide ceramic (often called alumina, AD 99.9).
