PURPOSE:To extremely enhance the strength of abrasive, by using filaments which is obtained by cutting long fibers formed by a wire shaving process, as a bond material, and by adding abrasive grain thereinto so as to obtain abrasive having a cutting sharpness and durability. CONSTITUTION:Filaments obtained by cutting steel group long fibers produced by a wire shaving process are subjected to carburization. Thus obtained filaments is uses as a bond material into which diamond abrasive grain is added. Further, thus obtained mixture is subjected to press-powder molding and is then sintered. Thereby it is possible to obtain relatively cheap abrasive with less deterioration of diamond abrasive grain.
