COMBINED GRINDING TOOL Russian patent published in 1997 - IPC

FIELD: mechanical engineering, production of combined grinding tools for abrasive working of blanks. SUBSTANCE: aim s to increase effectiveness of blanks working by combined grinding tools and to simplify the tool design a tool is proposed, in which big grain abrasive members are stationary mounted on disk body and sections with small grain abrasive layer on highly porous ceramic binder are fixed on movable members radially moving due to inertia forces during cutting fluid feeding through inner canals of movable member and pores of small grain abrasive layer into zone of cutting. EFFECT: increased effectiveness of blanks working by combined grinding tool and simplified its design. 3 dwg
