diamond grinding cup wheels used in a resin binder, a ceramic, a metal binding agent. Resin binder having good self-sharpening, flexible, good polishing performance advantages, the type epoxy, phenolic resins, polyvinyl alcohol, urethane resins, etc.companies with high diamond mounted points liquidity heat-resistant resin, developed a high concentration of independent pores (abrasive density 50%) low damage Jing cbn grinding wheels precision resin bonded diamond grinding wheel. Made of epoxy resin as a binding agent in a liquid, stirring the plane into a plurality of steps involved in the air bubbles, the bubbles instead of the traditional bubble material obtained (40 to 60) about the high vol% of porosity (pore size of 0.1 ~ lmm) porous resin bonded grinding wheel, resin wheel and make grinding performance is improved.
Vitrified diamond wheel with precise rigidity, heat resistance, corrosion resistance, easy to plug fever, high grinding efficiency, easy dressing and so on. Tanaka, T et al [9] O ~ l/8btm diamond abrasive grains, the use of low-melting binder is heated by a low temperature to prevent graphitization of the diamond abrasive grains during sintering occurs, the wood milling cutters success of the system out of the porous ceramic bonded diamond wheel. Japanese patent describes a method of manufacturing a high-performance vitrified diamond grinding cup wheels, the patent states that when Si02, Al. O. , B. O. When the weight ratio of CaO and other appropriate and does not require a reducing atmosphere during the sintering process and the inactive atmosphere, and can be sintered at a low temperature in the atmosphere 720 ℃, the diamond abrasive grains may not be oxidized.
