ABRASIVE TOOL MANUFACTURE METHOD Russian patent published in 1998 - IPC

Abstract RU 2108227 C1

FIELD: production of grinding, polishing and cutting wheels based preferably on organic binder. SUBSTANCE: method involves preparing abrasive lumpy mass by rolling on rolls; forming plates by calendering; punching annular billets from plates with following curing of annular billets. Abrasive mass is subjected to additional pressing with relative deformation extent of 30-60% prior to forming plates. Billets are made rectangular and provided with wedge-shaped end. Height of billets is product of plate height and average total drawing during forming, and width of billets exceeds diameter of punched billet by 6-8%. Billets are cut into plates for several passes with total drawing extent of 2-3. EFFECT: increased efficiency, simplified method and improved quality of abrasive tools. 1 tbl
