Common abrasives for grinding:
1, black corundum suitable for processing steel, for glass sandblasting, metal casting building floor. In the ordinary abrasive brown corundum hardness is slightly lower. However, in the grinding process, the grinding particle has good crushing resistance, which is suitable for grinding metals with high tensile strength, such as the rough grinding and heavy grinding of ordinary steel, especially for carbon steel, general alloy steel, and can also be used for the grinding of wrought iron and hard bronze.
2, white corundum is another basic variety of ordinary abrasives. Its hardness is slightly higher than brown corundum. During grinding, the grinding effect is good and the cutting force is strong. White corundum is suitable for grinding steels with high hardness. Such as high carbon steel, high speed steel, quenched steel, etc., but also suitable for easy to produce burn workpiece processing, such as cutting tools, thin wall workpiece grinding and alloy steel grinding.
3, single crystal corundum has good multi-edge cutting edge, high hardness, high toughness value, strong grinding force, small grinding heat, long abrasive cutting life, can be processed harder and tougher steel, such as stainless steel, high vanadium high-speed steel, etc., but also especially suitable for deformation, easy to burn workpiece grinding and large feed grinding.
4, microcrystalline corundum crystal size is small, high strength, good self-sharpness, can be used for deep grinding. In the grinding process, the microcrystalline corundum abrasive shows a micro-broken state and has good self-sharpness, so it is suitable for heavy load slow feed grinding with large grinding depth.
5, chrome corundum is rosy, so some people call it rose corundum. Its brittleness is moderate, cutting performance is good, suitable for a variety of high finish surface processing or form grinding.
6, zirconium corundum high strength, wear resistance is quite good, high grinding efficiency, grinding wheel surface is not easy to plug, suitable for heavy load grinding or rough grinding stainless steel, heat-resistant alloy steel, titanium alloy, high-speed high vanadium and other materials.
7, silicon carbide is suitable for the processing of non-ferrous metals and non-metallic materials, black silicon carbide is mostly used for grinding or cutting materials with lower strength, such as cast iron workpieces, non-ferrous metals, abrasives manufacturing, but also for the processing of stone and other non-metallic materials.
8. Green silicon carbide is mostly used for materials with high hardness and brittleness; Such as carbide, optical glass grinding processing. Feizhan abrasives production of black green silicon carbide. Particle size sand powder, is a big furnace smelting, particle size from 36 # -1800 #, national standard, Japanese standard to 8000 #. The product has high packing density, strong grinding ability, high hardness, strong cutting ability, uniform particle size standard, widely suitable for ceramic grinding block, hardware grinding, electronics, jewelry polishing, etc., is the best choice for friends.
