COMBINATION GRINDING WHEEL Russian patent published in 2002 - IPC

FIELD: mechanical engineering; machining metals; finishing blanks by means of abrasive wheels. SUBSTANCE: combination grinding wheel includes components for coarse-grained and fine-grained abrasive layers which are secured on faces of polyhedral change members which may periodically turn through angle corresponding to number of faces. Grinding by means of this wheel is effective in machining blanks of various parts in small batches due to possibility of machining these blanks on one machine in succession by means of one grinding wheel whose working surface is intermittent and has grains of different sizes. EFFECT: simplified construction of grinding wheel. 3 dwg
