The abrasive industry is a basic industry, but in mechanical processing it always occupies a very important place. In terms of abrasives, there are three aspects of improvement and advancement.
First, the abrasive physical structure improvements, such as the increase in the number of grinding grains by unit time effect artifacts, the increase in the growth of the average length, make the grinding surface grinding, which changes grinding unit time in addition to quantity, can effectively improve the efficiency;
Second, the application of superhard abrasive, mainly refers to metal powder, metal oxide or CBN superhard materials as fillers, such as resin, made of ceramic or metal bond abrasive applications. At present, the super-hard abrasive with high-precision and high-efficiency polishing effect has been widely recognized.
Third, the emergence of new abrasives such as micron-grade polycrystalline ceramics composed of microcrystalline abrasive, which contains fine grains of superfine, spherical layer abrasive polishing diamond, etc. with polyester film. The characteristics of these new abrasives lie, in the grinding, in the advantages of being able to show in an incisive and vivid way.
Throughout the development in the field of grinding, grinding in the future will be presented with increased demand for abrasives, judging from the current situation, it can only meet the needs of these new super-hard grinding products. As CBN abrasive has good thermal stability, high hardness, good abrasion resistance and other characteristics, so when high-speed abrasive grinding, high grinding efficiency, grinding tool life is also high, especially suitable for machining high speed steel, bearing steel, stainless steel, cold shock cast iron and other ferrous metal materials. In addition, to meet the various needs of ceramic bond grinding wheel, large hole high-speed grinding wheel, as well as different machining surfaces of grinding wheel, diamond saw blade, etc., will be with the progress of technology and will expand the scope of application, it becomes the milling products.
