Webb28 maj 2024 · Abrasive Jet Machining ( AJM) is a mechanical machining process where you cut or machine the workpiece by impacting a stream of high-velocity air (or gas, the air is normally used) carrying abrasive particles, on the work-piece surface. The abrasive particles are driven by a high velocity (about 180 to 200 meters per second) of air.
