In Abrasive Jet Machining, fine abrasive particles. (typically ~) are accelerated in a gas stream. (commonly air) towards the work surface. As the particles. impact the work surface, they cause small fractures, and the. gas stream carries both the abrasive particles and the. fractured (wear) particles away.
