ABRASIVE MASS FOR MANUFACTURING TOOL WITH HIGH STRUCTURE NUMBERS Russian patent published in 2017 - IPC B24D3/18 

FIELD: machine engineering.

SUBSTANCE: abrasive mass includes an abrasive, a ceramic binder, a filler in the form of aluminosilicate hollow spherical particles ranging in the range of 5 to 560 microns and particles of ground fruit bones in the range of 100 to 630 microns, gluing and moisturizing additives. As gluing and moisturizing additives in the amount of 15.5-20 vol. % it contains powdered dextrin in the amount of 75-150 vol. % of the ceramic binder and a 50% aqueous solution of lignosulfonate in the amount of 25-75 vol. % of the total filler content in the form of aluminosilicate and fruit seeds, with the following ratio of components, vol. %: the abrasive 26-42, the ceramic binder 5-21, the filler from aluminosilicate 2-15, the filler from fruit bones 4-12, the powder dextrin 7.5-12, the 50% aqueous solution of lignosulfonate 4,5-8, the natural pores - the rest.

EFFECT: providing increased strength and uniformity of the moulding mass.
