Vitrified corundum grinding wheel

Corundum grinding wheel is one of the most important abrasives. Corundum grinding wheel is to add a binder in the abrasive, the porous body through compacts made of dried and calcined. Due to the abrasive, binder and process variation, large differences in characteristics of the wheel, so the grinding process quality, productivity and economy have an important impact. Characteristics wheel is mainly determined by the abrasive strength, binders, hardness, structure, shape and size and other factors wheel variety. Press the abrasive can be divided into ordinary abrasive (corundum and silicon carbide) wheel. According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup wheel, disc wheel and so on; by binding agent can be divided into pottery wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of the grinding wheel abrasive, grain size, hardness, binding agents, shape, size and so on. Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed at the maximum operating speed of the wheel, do not break) and static balance test (when working to prevent vibrations caused by the machine). Grindstone at work for some time, it should be trimmed in order to restore the grinding performance and correct geometry. Corundum grinding wheels - corundum Grinding wheel size shape from the shape into flat wheels, double-sided concave grinding wheel, double bevel wheel, cylindrical grinding wheel, disc wheel, bowl grinding wheel, according to the needs of the machine structure and the grinding wheel system into a variety of shapes and sizes. Table 6 is commonly used in several wheel shape, size, code and applications. The outer diameter of the wheel should be as the election was bigger, in order to increase the speed of the wheel circumference, so to improve productivity grinding and surface roughness favorable. In addition, under the conditions of the machine rigidity and power permit, such as the choice of the width of the larger wheel, also can receive to improve productivity and reduce the effect of roughness, but high grinding heat-sensitive materials in order to avoid burns and workpiece surface cracks, wheel width should be appropriately reduced. Corundum corundum is high-quality aluminum oxide powder as raw material, refined and crystallized fused, high purity, good self-sharpening, acid corrosion, high temperature, stable thermal properties, it is slightly higher than the hardness of corundum, lower toughness, strong grinding ability, heat a small, high efficiency. It can be made with the abrasive, suitable for grinding high carbon steel, high speed steel and stainless steel fine-grained abrasive; also be used for precision casting and high-grade refractory. 1, high hardness, dense granules. Single particle circularity good. 2, the color white, no impurities, to ensure wear layer or wear-resistant paper color and transparency. 3, particle size distribution concentrated, consistent single particle form, with the least amount of wear up to the maximum effect. 4, which is selected from the more than two thousand degree heat by melting corundum made of high-quality raw materials, fine production from its chemical stability and acid, alkali effect does not occur, the heat-shrinkable minimal.
