Abstract: An abrasive tool having a spray-formed brazing filler layer and a manufacturing process thereof are described, in which drawing and adhering steps performed on a conventional brazing filler layer are simplified through spraying. A solvent, an adhesive, and a powder are sequentially mixed to form a brazing filler slurry; next, the brazing filler is sprayed on a substrate, so as to form a brazing filler layer with an appropriate thickness; and then, abrasive particles are adhered to the brazing filler layer, and then the abrasive particles are combined with the substrate through the brazing filler layer by brazing. The conventional drawing and adhering steps are omitted through spraying, and it is applicable for substrates with complicated shapes.

Abstract: A ceramic polishing pad dresser and the method for fabricating the same are provided. Abrasive particles are adhered onto a ceramic substrate by heating a ceramic powder to be vitrified, thus forming a ceramic diamond disk. Meanwhile, a plastic base is mounted on the bottom of the ceramic diamond disk. As for heating the ceramic powder to be vitrified, the ceramic powder with low melting point is disposed on the ceramic substrate, and to be heated to form a vitrified adhering layer, so as to adhere the abrasive particles disposed thereon to the ceramic substrate. The plastic base mounted on the bottom of the ceramic diamond disk is provided for bearing the ceramic diamond disk and has corresponding screw holes and positioning holes formed thereon for fitting the chemical mechanical polishing table to be mounted and reducing the manufacturing cost.
