FIELD: abrasive treatment processes and equipment, possibly manufacture of abrasive tools.
SUBSTANCE: abrasive tool includes abrasive grains, binder material and base. Abrasive grains of predetermined maximum diameter are bonded in single layer of matrix with base by means of binder material. Abrasive grains are oriented in matrix according to non-uniform pattern having omitting zone around each abrasive grain. Said zone has maximum radius exceeding maximum radius of predetermined-size abrasive grain. Methods for making such matrix of abrasive grain and for transferring it onto base of abrasive tool are given in specification.
EFFECT: improved quality of working due effectively decreased till minimum regular net of traces of abrasive grains on worked surface.
