METHOD FOR MOULDING OF ABRASIVE TOOL BLANKS Russian patent published in 2000 - IPC

Abstract RU 2149749 C1

FIELD: production of large-sized high wheels on vulcanite binder. SUBSTANCE: vulcanite abrasive mix is rolled into plates, annular blanks are cut out of the plates, which are assembled in a pack on a core. Then, the pack is subjected to preliminary and final packing by free settling. After preliminary packing the pack is turned in the outside diameter with formation of concavity described by formula y = ±2x1/2; the maximum value of concavity makes up ΔR = (0,2÷0,3)ΔH•D/H, where ΔH - blank maximum diameter before final packing; H-blank height before final packing. EFFECT: eliminated spills arising in the blank. 1 ex, 2 dwg
