The choice of particle size depends primarily on the surface roughness and grinding efficiency of the workpiece being ground. T41 green cutting disc sizeselection of Abrasive Material Selection The choice of abrasive material mainly depends on the workpiece material and heat treatment method. When the material with high tensile strength is used, the abrasive with high toughness is used. When the material has low hardness and high elongation, the brittle is selected. For abrasives and materials with high hardness, use abrasives with higher hardness and use abrasives that are not susceptible to chemical reaction by the processed materials.
Hardness: Only the resin bond diamond wheel has the characteristic of “hardness”. S grade or higher is generally used.
Bonding agent: There are four kinds of commonly used bonding agents, and their bonding ability and wear resistance are in the order of resin, ceramic, bronze, and electroplated metal, which are gradually stronger. The resin bond diamond grinding wheel has high grinding efficiency, good roughness of the workpiece to be processed, wide application range, good self-sharpness, not easy to block, low heat generation, easy to trim, and mainly used for the refining process. Ceramic bond diamond grinding wheel is mainly used for grinding various non-metallic hard and brittle materials, hard alloys, super hard materials and so on.
