Diamond grinding wheel with diamond abrasive material 8407 as the material, respectively, with a metal powder, a resin powder, ceramic, and metal plating as a binding agent, made into various shaped articles, for grinding, polishing, grinding tool called diamond abrasive. Diamond abrasive structure: diamond abrasive layer structure generally consists of work, the matrix, transition of three parts. Also known as a working layer of the diamond layer by the abrasive, the binding agent and a filler, the abrasive part of the work. Also known as the non-diamond layer the buffer layer, the binding agent, metal powder and a filler, is firmly connected to the part on the substrate of the diamond layer. Said ordinary abrasive abrasive characteristics of the project are: the shape, size abrasive, grain size, hardness, organizations and bonded abrasives abrasive hardness refers to the external force, the degree of difficulty from the abrasive surface shedding 8407, it reflects the strength of binding agent holding abrasive grains hardness depends primarily on the amount of binding agent to the number and density of abrasive grit off easily, said low abrasive hardness; contrary Sweden Assab 8407, said high hardness hardness level is generally divided into super-soft, soft, soft, medium, medium-hard, hard and superhard seven level, from these levels can be subdivided in a number of small magnitude. abrasive method for the determination of hardness, more commonly There are hand-cone method, mechanical cone method, Rockwell hardness measurement method and blasting hardness assay.
