The three parts of diamond abrasive tools: diamond abrasive tools are similar to diamond bits and diamond saw blade, etc., generally from three parts, the working layer, the transition layer and the matrix.. Working layer (diamond layer): it is composed of three parts, diamond abrasive, binder and pore, and it is part of grinding wheel.. Diamond is the theme of the grinding behavior; bonded abrasive grains bonded together with certain geometry of the abrasive; the compaction degree of the stomatal characterization of abrasives, it on the grinding efficiency and the quality of work have directly influence. The pores also play a role for heat dissipation and debris.. The thickness of the working layer of diamond tools is generally small, and the thickness of the working layer of diamond wheel is between 0.15 ~ 5.0mm. Transition layer (non diamond layer): the layer does not contain diamond, which is composed of bond and other materials. Its function is to combine the working layer firmly in the matrix, and ensure the complete use of the work layer, in order to simplify the manufacturing process sometimes can not transition layer, the work layer directly and substrate bonding. Such as wheel small flat wheel and bakelite matrix no transition layer. Base: it loads the working layer, and makes the abrasives fixed in the grinder or grinder. According to the different types of binders, diamond tools can be used in steel, aluminum, bakelite and other materials as matrix. General metal bonded abrasive tools made of steel matrix, resin bonded abrasives with aluminum alloy, bakelite or phenolic and aluminum material as matrix matrix in can ensure the strength and stiffness of the premise, the lighter the better, so the aluminum matrix is the most common.
