1. Abrasive Water Jet Machining. 2. Process Principle • An abrasive jet starts out the same as a pure water jet. • As the thin stream of water leaves the nozzle, abrasive is added to the stream and mixed. • The beam of water accelerates abrasive particles to speeds fast enough to cut through much harder materials. 3.

The abrasive jet machining process is the essence of abrasive water jet cutting and includes a high pressure stream of water with an abrasive. It blasts and erodes the workpiece to remove particulate matter, burrs, and materials. As is common with abrasive water jet cutting, the particles used for cutting are extremely fine and applied at high ...

In abrasive jet machining, the material is removed by the erosive action of a high-velocity stream of fine abrasive particles transmit on the work surface. This is the main principle behind the AJM machining process and this process lies in its ability to machine brittle materials with thin sections, especially in areas that are inaccessible by ...
