Microcrystalline corundum is another new abrasive product developed and produced by Ruishi Company in accordance with domestic and international markets in recent years. Microcrystalline corundum is a derivative of brown corundum, and its appearance, color and chemical composition are similar to brown corundum, which is obtained by changing the cooling crystallization method of corundum. Microcrystalline corundum abrasives are mainly divided into two types: F sand and P sand, which are characterized by small crystal size (50-280um) and abrasive grains formed by polymerization of fine crystals, which has good toughness, high strength and good self-sharpening.
It is made by fine crystal polymerization, with good toughness, high strength and good self-sharpness. Abrasive tools made of microcrystalline corundum are suitable for grinding stainless steel, carbon steel, ball-milled cast iron, etc. The grinding method is suitable for forming grinding, plunge grinding, fine grinding and heavy grinding.
