Natural and artificial abrasive abrasive abrasive points two categories. Natural corundum and diamond abrasives and so on. Natural corundum containing impurities, patchy, and expensive, rarely used, so the current manufacturing abrasive grinding wheels are mainly various artificial abrasive. Artificial corundum abrasives sub categories, silicon carbide type, hard type three categories.
Various artificial abrasive characteristics are as follows:
The main component of the class corundum abrasive is alumina. By bauxite and other raw materials at high temperatures
Electric furnace smelting together. Good diamond reinforced conrete tensile strength suitable for grinding materials, such as various steel. Press alumina content, crystal structure, different classes infiltrate corundum can be divided into the following categories:
â‘ corundum (A), also known as alumina corundum, was brown. Vitrified grinding wheel with its manufacture is usually blue or light blue. Corundum hardness and high toughness better able to withstand greater pressure grinding, suitable for grinding carbon steel, alloy steel, hard bronze and other metal materials. Corundum cheap, wider application.
