Abstract

To manufacture grinding members covered with extremely hard abrasive granules, instead of a base member of steel, a commercially available grinding tool of a corresponding shape and size made of a porous ceramic material is used as the base member. The base member is coated with an adhesive at the areas to be covered, the abrasive granules are applied and are pressed into the pores of the ceramic material; finally the adhesive is allowed to harden.
