Suction automatic sandblasting machine

The blasting machine uses compressed air as a power to form a high-speed jet beam to spray the spray at a high speed onto the surface of the workpiece to be treated to change the mechanical properties of the outer surface of the workpiece surface. Due to the impact of the abrasive on the surface of the workpiece and the cutting action, the surface of the workpiece is given a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thereby improving the fatigue resistance of the workpiece, increasing it and coating The adhesion between the layers prolongs the durability of the coating film, and also facilitates the leveling and decoration of the coating, removes impurities, mottling and oxide layers on the surface, and at the same time roughens the surface of the medium to cause residual stress on the surface of the substrate. And the effect of increasing the surface hardness of the substrate.
