Sandblasting

Description of the technology

Sandblasting (abrasive blasting) is a method of abrasive machining using loose abrasives by the kinetic method. In sandblasting, abrasive grains are propelled in a high-speed fluid (gas, liquid or gas and liquid) stream. The abrasive grains are accelerated by the fluid stream at such a high speed that, despite their low mass, their kinetic energy is sufficient to perform the machining (breaking the cohesion of the workpiece material).
