Abrasives industry is a basic industry, but in the machining has always occupied a very important position. Abrasives, there are three aspects to improve the breakthrough extraordinary. First, the abrasive physical structure improvements, such as the increase in unit time of the number of workpiece abrasive grinding the average length of growth, so that the grinding contact surface increases, which are to change the unit of time wear in addition to the amount of, effectively increasing the efficiency ; Second, the application of superhard abrasive, mainly refers to as the filler metal powder, metal oxide or CBN superhard materials, resin, ceramic or metal binder made of abrasive applications.
Superhard abrasive, high-precision, high-efficiency grinding effect has been widely recognized; the emergence of the third, new abrasives, such as the composition of the polycrystalline micron ceramic microcrystalline abrasives, including fine diamond grit spherical shell abrasive ultra-precision polishing of polyester film with. These new abrasives has the characteristics of their advantages in grinding head to show.
Looking at developments in the field of grinding grinding will abrasives, higher demands, to determine the current status of super-hard products precisely to meet these new grinding needs. Such as CBN abrasive has a good thermal stability, high hardness, good wear resistance properties, the abrasive grinding line speed, high efficiency grinding, abrasive life expectancy, especially suitable for processing high-speed steel, bearing steel, stainless steel, chilled cast iron and other ferrous materials. In addition, to meet the various needs of ceramic bonded grinding wheel, large pores of high-speed wheel and machined surface abrasive grinding wheel manufacture, diamond saw blade so as technology advances and expand the scope of application to become a mainstream product in the grinding.
