The process of drawing, cutting, grinding circle and other processes is refined.. Mainly used in various aluminum alloy, zinc casting various products of the burr removal and cleaning. The gravity is close to the steel, the hardness is low, so it can not only remove the large burr while the surface of the product, but also form a anticorrosive coating on the metal surface.. In addition, because of the different types of abrasive dust and aluminum, the ignition temperature is extremely low, good safety. And the surface of the workpiece has a significant whitening effect.
