Abrasive Water Jet Machining. How Water Jet Cutter Works?

2021-5-28 · 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. The work-piece material of your AJM is stressed and fractured ...
