اقرأ أكثرWhen abrasive particles thwack the work surface at high velocity, they remove material by micro-cutting (impact erosion). AJM is commonly used surface cleaning, such as removing oxide layer, smears, coating or colour present of solid surface. It can also be used for deburring and engraving hard brittle materials.

اقرأ أكثرTypical Abrasive Air Jet (AAJ) systems operate ~1 MPa, and are suitable for micromachining or cleaning applications. Alternatively, AWJ systems typically operate at pressures up to 400 MPa, and systems up to 600–700 MPa are available [ 18 – 21 ]. They are suitable for deep cutting, even on hard materials.
اقرأ أكثرMeaning of Abrasive Jet Machining (AJM): In this process a focused steam of abrasive particles (of size 10 to 40 microns) carried by high pressure gas or air at a velocity of about 200 to 400 m/sec is made to impinge on the work surface through a nozzle, and the work material is removed by erosion by the high velocity abrasive particles.
