ABRASIVE TOOL MANUFACTURING PROCESS Russian patent published in 1999 - IPC

Abstract RU 2138387 C1

FIELD: abrasive industry. SUBSTANCE: process includes preparation of abrasive vulcanite mixture and rolling of it into plates. After circular blanks are cut out of them, and blanks are assembled into stack, preliminary and final molding is performed. Then blanks are subjected to preliminary mechanical treatment, vulcanization and to final mechanical treatment. In this case, preliminary mechanical treatment is performed by value П+(ΔDb-ΔDw), where П is allowance for external diameter of molded blank; ΔDb is zone of tolerances for molded blank external diameter; ΔDw is zone of tolerances for manufactured wheel external diameter. The above-indicated actions provide for 5-9- per cent economy of initial mixture. Labour consumption of final grinding of wheel blanks is one-fifth-one-sixth of usual value. EFFECT: enhanced efficiency.
