Machining Silica Sand

AJM differs from age old sand blasting technique by the achievable level of accuracy and precision. AJM utilizes various abrasives including alumina, silicon carbide, glass beads, sodium bicarbonate, etc.; whereas sand blasting predominantly utilizes only silica sand (SiO 2).

Abrasive jet machining (AJM) is one of the most widely used non-traditional method for material removal. In this process, jet of gas and fine abrasive particles of different mesh size strikes the work piece at very high speed ranging from 300 m/s to 500 m/s [1]. The material is removed by erosive action of abrasive particles.
