Application of brazing technology to diamond tools manufacturing

This review covers the definition, classification of diamond tools and the brazing technology applied in diamond tools manufacturing. The paper outlines the principles of different connection mode of diamond particles and base material, illustrates the diffusion brazing mechanism and advantage of the pre-alloyed powder application, discusses the matching principles of brazing filler metal, brazing technology and brazing equipment, reviews the developments of brazing technology in diamond tools manufacturing according to the development status domestic and overseas, and predicts the development direction of brazing technology applied in diamond tools manufacturing. This paper can provide the reference for investigations on domestic diamond tool manufacturing and welding industry.
