Brown corundum grinding wheel is the most important type of grinding tool in grinding. The grinding wheel is a porous body made by adding a bond into the abrasive, pressing, drying and baking. Due to different abrasives, binders and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the processing quality, productivity and economy of grinding. The characteristics of grinding wheels are mainly determined by the factors such as abrasive, grain size, bond, hardness, structure, shape and size.
According to the abrasive used, it can be divided into ordinary abrasive wheels (corundum and silicon carbide).
According to 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 bond, it can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel, etc. The characteristic parameters of grinding wheel mainly include abrasive, grain size, hardness, bond, organization number, shape, size, linear speed, etc.
Because the grinding wheel usually works at high speed, the rotation test (to ensure that the grinding wheel will not break at the highest working speed) and the static balance test (to prevent machine tool vibration during operation) should be carried out before use. After working for a period of time, the grinding wheel shall be trimmed to restore grinding performance and correct geometric shape.
