The jet drags the abrasive through the material in a curved path and the resulting centrifugal forces on the particles press them against the work piece. The cutting action is a grinding process where the forces and motions are provided by water, rather than a solid grinding wheel. Quality finish Materials cut by the abrasive jet have a smooth, satin-like finish, similar to a fine sandblasted finish. No heat in machining process Abrasive jets abrade material at room temperatures. As a result, there are no heat-affected areas or structural changes in materials.
Abrasive jets can also machine hardened metals and materials with low melting points.
Environmentally friendly Abrasive jets use garnet as an abrasive. Garnet is a reddish natural crystal, with a Moh hardness of 6.5 to 7.5. No noxious gases or liquids are used in abrasive jet machining, nor are there any oils used in the machining process. No heavy burrs are produced by the abrasive jet process. Parts can often be used directly without deburring.
