An abrasive tool comprises a base and an abrasive powder bonded to the base in the form of a single-layer structure in which the particles do not substantially overlap or rest one upon another. For the bonding purpose the abrasive powder is either dispersed in a dilute solution of a binder resin and a solvent for subsequent application of the solution to the base or is spread over and fixed to a binder resin coat formed beforehand on the base.

Abrasive tools

A composite spherical-particle abrasive comprises spherical particles and abrasive particles, each spherical particle being coated with a plurality of abrasive particles. The composite abrasive particles are dispersed in a binder resin, and the dispersion is applied as an abrasive layer or coat to a backing to provide an abrasive tool. A grinding method uses such a composite spherical-particle abrasive tool.
