ABSTRACT:
A composite abrasive-articles according to the present invention is obtained by: mixing diamond pieces of abrasive articles or cubic boron nitride pieces of abrasive articles and metal powder, molding this mixture into a uniformed small piece of abrasive articles, then or simultaneously with this molding, completely sintering the uniform small piece of abrasive articles after the molding, and mixing the completely sintered piece of abrasive articles after the sintering with resin, metal or glass of a low melting point so as to be solidified into a predetermined shape. In the composite abrasive-article of this type, the completely sintered piece of abrasion articles made of the diamond pieces of abrasion articles or cubic boron nitride piece of abrasive articles and metal powder is dispersed and solidified in a matrix made of either resin, metal, or glass having a low melting point. The composite abrasive-articles are preferably used for grinding, polishing, and/or cutting metal, ceramics, stone, or the like.
