A shot blasting machine uses a high-speed rotating impeller to project steel shot or grit onto the surface of a workpiece. It is primarily used for surface cleaning, strengthening, deburring, and pretreatment. Its core functions include:
Surface Cleaning: Removes impurities such as scale, rust, and welding slag from the metal surface to improve surface cleanliness. It is commonly used for pretreatment of steel structures, castings, and forgings.
Strengthening: The impact of steel shot creates compressive stress on the metal surface, improving fatigue strength and corrosion resistance. It is suitable for automotive parts, aerospace components, and other applications.
Deburring and Shaping: Removes burrs from workpiece edges, improves surface roughness, and enhances the adhesion of subsequent coatings or plating.
Pavement Treatment: In road construction, it is used to remove laitance from asphalt or concrete surfaces and increase the friction coefficient of the road surface (e.g., crawler shot blasting machines).
