BUILTUP GRINDING WHEEL Russian patent published in 1999 - IPC

FIELD: manufacture of abrasive tools, namely for depth peripheral grinding of hard-to-deform materials. SUBSTANCE: grinding wheel includes shaft with two mounting flanges having tapered end surfaces and abrasive discs arranged between flanges and inclined by angle α relative to rotation axis. Grinding wheel is also provided with two additional mounting flanges with tapered end surfaces. Each flange is arranged on shaft with possibility of engaging with abrasive disc and with one of mounting flanges. Abrasive discs are in the form of cutting off wheels mounted without axial gap. All mounting flanges are arranged with possibility of mutual rotation and they are designed for controlling inclination angle of wheels relative to their rotation axis by means of tapered end surfaces inclined by angle α/2. Such angle provides possibility of dressing wheels at their normal arrangement. EFFECT: enhanced strength and operational parameters of tool. 5 dwg
