Description

Shot blasting means using rotary vane wheel with high speed to blast abrasives to hit work pieces for cleaning the surfaces or distort the surfaces crystal lattice to improve the hardness of the surfaces.Before shot blasting, the integrality of the shot blasting machine should be checked up. Right current, blasting angle and shot blasting speed should be chosen according to different types of shot blasting machine. The quality of abrasives has great affection on the quality of surface treatment, such as the hardness, grain size and metallographic structure of abrasive all can affect the shot blasting effect.
