ABRASIVE ARTICLE AND METHOD OF ITS MANUFACTURING Russian patent published in 2024 - IPC B24D3/00 B24D18/00 C09K3/14 A63D15/14 

FIELD: various technological processes.

SUBSTANCE: group of inventions relates to the manufacture of abrasive articles and is intended for creating surface roughness with simultaneous application of a thin layer of fine abrasive material on the working surface of the article to ensure strong contact and prevent slippage of working surfaces. Abrasive article is made from mixture containing multiple abrasive particles and binder. Abrasive particles used are polyfractional composition of abrasive powders based on B₄C, or SiC, or Al₂O₃, or SiO₂, and binder used is polyvinyl alcohol in form of 10% aqueous solution at said ratio of components. Disclosed is a method of making an abrasive article.

EFFECT: when using the abrasive article in the billiards, the surfaces are adhered, which eliminates the slippage of the cue when hitting the billiard ball.
