Abstract
An abrasive tool includes a substrate, a plurality of abrasive particle groups, and a bonding layer. The abrasive particle group consists of a plurality of abrasive particles grouped together. The abrasive particle groups are disposed in a regular pattern on the surface of the substrate and fixed on the surface by the bonding layer. To control the disposition of the abrasive particle groups, an abrasive particle template is used to form the required pattern. The size of the abrasive particle positioning holes on the template is used to adjust the number of particles in an abrasive particle group.
