What are the advantages of diamond grinding wheel structure
Dec 30, 2021
Diamond grinding wheel is the most important kind of grinding tool in grinding. Grinding wheel is a porous body made by adding binder to abrasive, pressing, drying and roasting. Due to different abrasives, binders and manufacturing processes, the characteristics of grinding wheels are very different, which has an important impact on the machining quality, productivity and economy of grinding. The characteristics of grinding wheel are mainly determined by abrasive, particle size, binder, hardness, structure, shape and size.
According to the abrasive used, it can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel, natural abrasive, superhard abrasive and (diamond and cubic grinding wheel, boron nitride, etc.) grinding wheel;
Diamond grinding wheel can be divided into flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup grinding wheel, disc 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, viscosity, hardness, binder, shape, size, etc.
Since the grinding wheel usually works at high speed, the rotation test (to ensure that the grinding wheel will not break at the maximum working speed) and static balance test (to prevent machine tool vibration during operation) shall be carried out before use. After working for a period of time, the grinding wheel shall be trimmed to restore grinding performance and correct geometry.
