GRINDING WHEEL Russian patent published in 1998 - IPC

FIELD: mechanical engineering, grinding of workpieces of various materials. SUBSTANCE: grinding wheel has grooves on the ends, having the shape of an equilateral trapezoid in radial direction and in cross-section. The larger base of each trapezoid in radial direction is positioned on the side of the wheel mounting surface, and in cross-section-on the side of the wheel end. The length of the grooves exceeds the value of half-difference of diameters of the new and maximum worn-out wheels by 3 to 5 mm, the depth of the grooves exceeds the value equal to half the wheel height by 0.5 to 1.0 mm. The grooves are filled with solid lubricant. EFFECT: enhanced efficiency. 5 dwg
