Difference Between AJM and USM

This abrasive jet possesses enough kinetic energy to realize material removal by erosion (due to the impacts of hard abrasives) On the other hand in ultrasonic machining (USM) an abrasive slurry (abrasive particles suspended in a liquid medium) is delivered in the small gap between a vibratory tool and the workpiece Get price
