The sandblasting process uses compressed air as the power to form a high-speed jet beam, and sprays the material and other high-speed jets to the surface of the workpiece to be treated, so that the appearance of the outer surface of the workpiece changes. A certain degree of cleanliness and different roughness improve the mechanical properties of the workpiece surface.
 
The Role of Sandblasting:
1. Sandblasting can clean the dirt (such as oxide scale, oil and other residues) on the surface of the workpiece, improve the smoothness of the workpiece, and make the workpiece reveal a uniform and consistent metal color, making the workpiece more beautiful.
2. Sandblasting can clean the tiny burrs on the surface of the workpiece and make the surface of the workpiece more flat, eliminating the harm of burrs and improving the grade of the workpiece. And sandblasting can make small rounded corners at the junction of the workpiece surface, making the workpiece more beautiful and more precise.
3. Improve the mechanical properties of parts. After the mechanical parts are sandblasted, uniform and fine concave and convex surfaces can be generated on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubricating conditions, reducing noise and improving the service life of the machine.
4. Lighting effect. Sandblasting can achieve a matte finish on the surface of the workpiece.
