Application of steel shot in shot blasting machine

The steel shot is widely used in the Shot Blasting machine, mainly for surface treatment, cleaning, strengthening and forming processes. The following is the specific application of steel pellets in the shot blasting machine and its working principle:

       1. Surface cleaning

       Steel balls are often used to clean up impurities such as oxide, rust, oil and welding slag on metal surfaces.

     Application Scenario:

     The shot blasting machine shoots the steel shot onto the workpiece surface through a high-speed rotating impeller.

     The impact force of the steel ball removes surface impurities and makes the surface of the workpiece clean and smooth.

    2. Surface strengthening (Shot Peening)

    Steel pellets are used to improve the surface hardness and fatigue resistance of metal workpieces.

    Application scenario:

    Auto parts: such as gears, springs, connecting rods, etc.

    Aerospace components: such as engine blades, landing gear, etc.

   Mechanical parts: such as bearings, molds, etc.

   Working principle:

   The steel pellets impact the workpiece surface at high speed to form a compressive stress layer.

   The compressive stress layer can improve the fatigue strength and durability of the workpiece.

   3. Surface molding

   Steel pellets can be used for forming metal surfaces, such as increasing roughness or forming specific textures.

    Application scenario:

   Increase the coating adhesion: the surface of the workpiece is shot blasted before painting to form a rough surface to        improve the coating adhesion.

   Decorative treatment: such as matte treatment of stainless steel surface.

    Working principle:

    The roughness and texture of the workpiece surface can be controlled by adjusting the particle size, shape and projectile   speed of the steel shot.

   4. Deburring and chamfering

    The steel shot can be used to remove burrs and sharp angles from the edges of the workpiece, making it smoother and      safer.

   Application scenario:

   Mechanical workpiece: such as sheet metal parts, stamping parts, etc.

   Casting parts: such as cast aluminum parts, cast steel parts, etc.

    Working principle:

   The steel shot impinges on the edge of the workpiece, removing burrs and forming a smooth chamfer.
