Method of manufacturing a profiled grinding wheel
Abstract
Abstract A METHOD OF MANUFACTURING A PROFILED GRINDING WHEEL IN WHICH A GRINDING BAND IS PROVIDED ON THE PROFILED CIRCUMFERENCE OF A SUPPORTING DISC.,THE BAND BEING BUILT UP FROM A SYNTHETIC BINDER, AND DIAMOND GRAINS. STARTING MATERIAL IS A CERAMIC GRINDING WHEEL WHICH, AFTER KPROFILING, IS USED FOR GRINDING A COUNTER PROFILE IN A MOULD. BY REDUCING THE DIAMETER OF THE SUPPORTING DISC, A GAP IS FORMED BETWEEN THE CIRCUMFERENCE OF SAID DISC AND THE COUNTER PROFILE IN THE MOULD, THE HEIGHT OF SAID GAP BEING EQUAL TO THE THICKNESS OF THE GRINDING BAND TO THE PROVIDED. A MIXTURE OF SYNTHETIC BINDER AND DIAMOND GRAINS IS PROVIDED ON THE CIRCUMFERENCE OF THE SUPPORTING DISC. BY ROTATING THE SUPPORTING DISC IN THE COUNTER PROFILE, SAID MIXTURE IS DISTRIBUTED ACROSS THE GAP AND A GRINDING BAND OF CONSTANT THICKNESS IS FORMED. ALLOPERATIONS ARE CARRIED OUT WITH THE SAME FIXTURE OF THE SUPPORTING DISC AND THE MOULD.
