Diamond grinding wheel selection

Diamond grinding wheel than with boron carbide, silicon carbide, corundum and other general abrasive grinding wheels made ​​of sharp edge angle, wear, long life, high productivity, good processing quality, but the price is expensive, making it suitable for grinding carbide, cutting tools  , high hardness brittle semiconductor materials difficult to machine. The features include abrasive diamond wheel type, size, hardness, density, binders, wheel shape and size. Abrasive: extensive use of synthetic diamond (JR), based on its crystal form and particle strength, of various types, according to their specific purposes selected models. Granularity: To  synthetic diamond  roughness of diamond grinding productivity and consumption of three aspects to consider. Hardness: Only the resin bond diamond wheels have the "hardness" of this feature. Generally use S (Y1) or higher. Binders: there are four commonly used binding agent, the binding capacity and wear resistance with a resin, ceramic, bronze, plated metal is sequence, in order crescendo. Resin bonded diamond grinding wheel, high efficiency, the workpiece roughness, and apply a wide range of good self-sharpening, easy to plug, heat a small, easy to repair, mainly used for grinding processes. Vitrified diamond grinding wheel is mainly used for a variety of non-metallic brittle materials, carbide, hard materials, such as grinding. Concentration: concentration selected according to size using the wheel, binding agents, shape, processing methods, the production efficiency and the requirements of the wheel life. High concentration of diamond grinding wheel shape retention ability, and low concentrations of grinding wheel, diamond consumption tends to lower some, as appropriate, should be selected according to need. Shape and size: according to the workpiece shape, size and choice of machining conditions
