ABSTRACT:
A resinoid-bonded grinding wheel employing hard abrasives such as cubic boron nitride or diamond is formed with a support member made of a vitrified grinding wheel. The support member has sealing layers on the surfaces thereof for avoiding the penetration of coolant into the support member. A method for forming the wheel includes mounting a grinding element on a radial peripheral surface portion of the support member and applying a sealing layer to the remaining surface portions of the grinding element for preventing penetration of the coolant into the support member and generation of vibrations in the grinding wheel during operation due to rotational imbalance caused by the presence of coolant within the support member.
