Grinding Wheel: Specifiions Manufacturing Process by ...
· The heat carrying capacity of the wheel is required to be higher for the higher temperatures generated due to grinding carried out at high speeds. If the porosity is kept higher for this purpose, when the grinding wheel rotates at a high speed, there is a possibility that the strength of the grinding wheel may be less. Hence a correct balance of this is maintained. A vitrified porous bond .
