Abstract

PURPOSE: To improve grinding performance and strength of offset type resinoid grindstone by producing porous resin stuff of high porosity so as to reduce bulk specific gravity of the grindstone down to that not more than 2.2 with its interbond value of 0.2.
CONSTITUTION: Amount of resin such as phenol resin or the like is adjusted to the degree of 20W26% with respect of grind granules, and amount of the grind granules put into the resin at the time of molding are reduced by the degree of 5W10% as compared with normally mixed amount thereof, so that bulk specific weight of molded grindstone including glass fibers and the like added thereinto as reinforcement is reduced down to that not more than 2.2 with its interbond value of 0.2 or less, resulting that thus molded offset type resinoid grindstone has high porosity and sufficient rigidity and strength.
