The purpose of this study is to establish a thermal dressing technique with moving heat source for resinoid bond wheel, in which heat resistance of bonding material is markedly lower than that of vitrified bond. In this paper, a single pulse of CW : YAG laser introduced as a heat source is irradiated on resinoid bond abrasive stick to make clear a foudamental phenomenon of laser dressing, analyzing transformation, profile of resinoid surface, stiffness of grain mounting and so on. Main conclusions obtained in this paper are as follows : (1) Transformation of resinoid bond, releasing abrasive grain and vaporization of bonding material take place with laser irradiation. (2) The depth and diameter of heat affected structure increases with increasing power density and irradiating time of a laser beam. (3) A stiffness of grain mounting decreases as a distance to an abrasive grain from a beam center decreases in heat affected surface.
