ABSTRACT:
A grinding wheel for use in a grinding machine, wherein a plurality of grinding tips are bonded on the periphery of a wheel core having a disk-like shape using a bond which forms a bonding layer between the wheel core and the grinding tips. The grinding wheel is further provided with means for preventing coolant from entering inside of the abrasive layer and/or bonding layer, thereby preventing the bonding layer from being swelling by the coolant. In a first embodiment, the preventing means is composed of rubber layers formed on the both side surfaces of the grinding wheel at the places corresponding to the radial position of the bonding layer. In another embodiment, the preventing means is composed of water-repellant material capable of repelling water. Such material is composed of silicon or fluorine resin and is soaked into the grinding tips.
