Read OnThis schematic shows grinding wheel structure, showing abrasive grain, bond, porosity, and filler components. Abrasive product bonds are generally classified as organic (resin, rubber, and so forth), vitrified (glass or glass …
Read OnAbstract: An improved resin bonded grinding wheel composition is shown making use of a kyanite or sillimanite or andalusite filler or mixtures thereof. More particularly the grinding wheel is a hot pressed phenol formaldehyde wheel having an alumina-zirconia abrasive with a kyanite additive therein. These wheels can be used for heavy duty metal ...
Read OnThe use of metal fillers in organic resin bonded grinding wheels has a serious shortcoming. Heretofore there was no known way of softening the grinding grade of this type of wheel. Grinding grade is the term used to denote the tenacity with which the bond--resin plus fillers--clings to the abrasive grit in time of stress, i.e., during grinding ...
