Abstract
An abrasive-particle grinder and a method of manufacturing the grinder, in which the bonding force between super-abrasive particles and a binder is enhanced, attrition of the binder during a grinding process is increased, and physical properties of the grinder are improved. The grinder comprises super-abrasive particles as grinding particles and metal powder as a binder. The binder is formed into a porous body and then at least the surface thereof is denatured to ceramic. Protrusion of the abrasive particles is first controlled and then grip of the abrasive particles is controlled.
