Sandblasting uses compressed air as power to form a high-speed jet beam, which sprays the material into the surface of the workpiece to be treated at high speed. By using the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface can obtain a certain degree of cleanliness and different roughness, so as to improve the mechanical properties of the workpiece surface. If the quenched spiral bevel gear is sandblasted, not only the surface finish is improved, but also the surface fatigue strength is improved.

Our Shandong No.2 Machinery Company have 2 sets of sandblasting machines to deal with burrs. This is the normal process.
