Production technology of brown corundum/brown corundum grinding wheel for grinding wheel; Brown corundum grinding wheel is the main type of grinding tool in grinding. Grinding wheel is a porous body made by adding binder into abrasive, pressing, drying and roasting. Because of different abrasives, binders and manufacturing processes, the characteristics of grinding wheels are very different, which has an important impact on grinding quality, productivity and economy. The characteristics of grinding wheels are mainly determined by abrasive, particle size, binder, hardness, structure, shape and size. According to the abrasives used, it can be divided into ordinary abrasives (corundum and silicon carbide, etc.) grinding wheels. According to the shape, it can be divided into flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup grinding wheel, dish grinding wheel, etc. According to the binder, it can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel and metal grinding wheel. The characteristic parameters of grinding wheel mainly include abrasive, particle size, hardness, binder, organization number, shape, size, linear speed and so on. Because the grinding wheel usually works at high speed, before use, it should be tested for rotation (to ensure that the grinding wheel will not break at the working speed of * *) and static balance (to prevent the machine tool from vibrating when working). After working for a period of time, the grinding wheel should be dressed to restore grinding performance and correct geometry.
