The Silicon Carbide Brush is specially used to deal with the surface of the metal, such as cast iron, aluminum, steel. Metal parts produced by cutting or die casting will inevitably have burr or flanging. If the burrs are not removed, it will lead to the accumulated errors when we assemble these parts and affect the accuracy of the final products. Also, these burrs will more likely rust and affect the service life of the products. For this reason, the deburring process is very essential.
