GRINDING WHEEL Russian patent published in 1998 - IPC

FIELD: machine engineering, namely grinding parts of different materials. SUBSTANCE: grinding wheel includes body with abrasive layer 1 having rows of radial ducts 2 opened to peripheral working surface and designed for supplying cutting fluid. Said body is in the form of faceplate 4 with turning. Pressure lubricator 6 is placed onto said faceplate, it has through opening shifted relative to circle axis and connected with said turning. There are axial grooves 3 on mounting surface of said abrasive layer. Said grooves are connected with radial ducts 2 and with turning of faceplate. Said radial ducts are in the form of cone-cylinder openings. Small-diameter cone base of each opening is arranged in peripheral working surface of wheel. Said turning, axial grooves and radial ducts are filled with grease lubricant. Number of axial ducts is equal to that of rows of radial ducts. EFFECT: improved design. 3 dwg
