GRINDING WHEEL Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: grinding wheel is used in combined grinding of blanks made of different materials. Grinding wheel is of angular profile. Through radial channels in the form of tapered-cylindrical holes are made in central part of wheel. Holes are coupled with axial recesses on fitting surface of wheel and filled with semisolid lubricant. Wheel is also provided with axial channels, cross-section of which is shaped as isosceles trapezium. Channels are positioned on concentric circumferences and filled with solid lubricant. Design formulae are given for determination of angular spacing in arrangement of channels on concentric circumferences, number of circumferences, etc. In process of machining, effective action of lubricant is provided, and thermal stress is reduced. EFFECT: enhanced tool strength. 2 dwg
