METHOD OF PRODUCING GRINDING TOOL WITH ORIENTED GRAINS Russian patent published in 2009 - IPC B24D18/00 

FIELD: process engineering.

SUBSTANCE: in preparing abrasive mix, grinding grains are mixed with moisteners, binders and fillers, thus produced mix is triturated on sieve. Vertical electrodes representing thin-wall are placed directly in the mold to set required orientation of grains and to electric field between electrodes. Abrasive mix is laid into aforesaid mould through vibrating sieve to produce abrasive mix layer of necessary thickness. Then electrodes are removed from the mould by uplifting them strictly upward and abrasive mix layer outer surface is leveled to remove surplus material. After moulding mix is withdrawn from the mould and subjected to thermal treatment.

EFFECT: higher efficiency, better orientation of grains.
