Abstract
The abrasive particle layer of resin bonded abrasive tool is constructed by resin binder phase consisting of heat hardening resin, for example, phenol resin etc. and super abrasive particle of diamond (or CBN etc.) distributed in this resin binder phase. The wear resistant filler consisting of SiC, for example, as hard filler and hollow glass and metal coated amorphous carbon is distributed in resin binder phase. The amorphous carbon is made to spherical shape and metal coating layer consisting of Cu, for example, as the metal having high thermal conductivity, is set on a surface of this amorphous carbon.
