METHOD FOR MANUFACTURING ABRASIVE ARTICLES Russian patent published in 1997 - IPC

FIELD: production of abrasive articles. SUBSTANCE: proposed method involves moulding of abrasive powder at its static and dynamic loading by shock wave of 0.5 to 0.65 MW per one gram of powder with subsequent thermal treatment. Prior to moulding magnesium oxide is added to the abrasive powder in amounts of 3 to 8 per cent of the total powder mass. After moulding the article is subjected to thermal treatment during 2 to 4 hours at a temperature from 1500 to 1600 C. EFFECT: improved quality of abrasive articles. 1 tbl
