The blasting machine is a machine that uses compressed air as a power to form a high-speed jet beam. It can spray at a high speed to the surface of the work-piece and change the mechanical properties of the outer surface of the work-piece surface. Due to the impact of the abrasive on the surface of the work-piece , the surface of the work-piece is given a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the work-piece are improved, thereby improving the fatigue resistance of the work-piece, increasing it and coating The adhesion between the layers prolongs the durability of the coating film, and…
