Sand Blasting Machine is a processing machine, due to the impact of the workpiece surface and cutting of the workpiece surface which obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface is improved. Thus it increases the fatigue resistance of the workpiece, and the adhesion between the coating to extend the durability and paintcoat, not only extends the durability of film but also helps conducive to the leveling and decoration of the paint, remove the impurities, variegated and oxide of surface, while the media surface is roughening to eliminate the residual stress and improve the hardness of the substrate.
