(A), before Grinding wheel is the most important one class of abrasive. The abrasive wheel is a binding agent is added, the compacts, Drying and calcining the porous body made. As abrasives, binders and manufacturing process is different, the wheel characteristics vary greatly, so the grinding machining quality, productivity and economy have a significant impact. Mainly by the characteristics of grinding abrasive particle size, binder, hardness, structure, shape and size and other factors. (Two), wheel classification Wheel variety, according to the abrasive can be divided into ordinary abrasive (corundum (Al2O3) and silicon carbide, etc.) Grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel ; wheel shape can be divided according to level grinding wheels, Bevel wheel, cylindrical grinding wheels, cup wheels, disc wheel, etc.; binding agents can be classified according to the ceramic grinding wheel, Resin grinding wheel, rubber wheel, metal grinding wheel. (Three), wheel properties Wheel is made of abrasives and binders central circular hole abrasive. Characteristics of the abrasive wheel, grain size, hardness, binders, shape, and size and other factors to determine, Respectively, are presented below. 1, abrasives and selection Abrasive wheel is the main raw material manufacturing, it bears a cutting work. Therefore, the abrasive must be sharp, And have a high hardness, good heat resistance and a toughness.
Monocrystalline corundum ceramic grinding wheel Description: Scope: high manganese steel, high chrome, nickel, molybdenum alloy steel, chilled cast iron, all kinds of hardened steel, all kinds of cast iron, glass, precious stones high hardness soft and tough materials. Monocrystalline monocrystalline corundum corundum grinding wheel is as raw material into various shapes of bonded abrasives can be used to grind stainless steel, high vanadium high speed steel toughness, high hardness materials and easily deformed tool. Monocrystalline corundum and corundum and corundum relatively high hardness, toughness, spherical particles were single crystals, crush resistance is strong. Monocrystalline corundum color is pale yellow product type hexagonal crystals.
