METHOD FOR SHAPING OF DIAMOND-ABRASIVE WHEEL OF COMBINED GRANULARITY WITH AIR-ABRASIVE JET Russian patent published in 2009 - IPC B24D18/00 B24D5/14 

FIELD: technological processes.

SUBSTANCE: invention is related to the field of machine building and may be used in shaping of diamond-abrasive wheels with combined granularity under conditions of separate supply of liquid binder and polishing material. Mandrel with hub and easily destroyed disks are installed in drying chamber, imparting continuous rotation to it. A layer of binder is applied onto hub by means of nozzle with regulation of its amount by measurement of gap between nozzle and gap. Polishing material is supplied under pressure with the help of air-abrasive jet through nozzle with channels or separate nozzles provided it penetrates and fixes in applied binder layer. Density of polishing material application is regulated with amount of supplied polishing material and speed of mandrel rotation, which is assigned provided that each layer is previously dried. Number of channels in nozzle or separate nozzles for supply of polishing material is equal to quantity of abrasive granularity numbers, used in making of diamond-abrasive wheel.

EFFECT: technological resources are expanded due to provision of possibility to produce both simple and complex polishing wheels, and their manufacturing cost is reduced.
