METHOD FOR PRODUCTION OF ABRASIVE BODIES AND SINTERED ABRASIVE MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2098261 C1

FIELD: production of grains of grinding material and abrasive tools, precisely, abrasive bodies used in vibroabrasive and planetary-abrasive working. SUBSTANCE: molding mixture is extruded for abrasive bodies or sintered abrasive material in the form of band with its simultaneous or subsequent incision from both sides to a depth equals to 0.2-0.9 of band thickness, parallel on each side and crossing at an angle of not less than 20 deg relative to the other side to form grooves triangle in shape and after drying, band is broken by incisions. Band is incised by forcing mixture or band into slot between surfaces of two rotating shafts whose surfaces has projections located in helical line of the same direction. Projection side surfaces are described by evolvent. EFFECT: higher efficiency. 2 cl, 1 tbl
