1. A method of double-sided grinding of flat butting faces, particularly small cylindrical ceramic, consisting in objects being ground are simultaneously ground on both sides by two grinding wheels, of rotation axis on one straight line, on the rims of the grinding wheels is made a conical insertion chamfer, and the ground objects are moved by a plane motion, in the plane perpendicular in relation to spindle's axis, characterised in that on the faces of both grinding wheels, apart from the insertion chamfer, is shaped a conical working surface of the angle (α), preferable within the limits up to (α) = 2 degrees, whose value is selected depending on the volume of allowance, leaving in the central part of both grinding wheels a flat honing surface, objects are inserted in circular trajectory, preferably externally tangential to a circle of the diameter lesser than the interior diameter of the grinding wheels' working ring, however prior to entering the processing zone these objects are placed symmetrically in relation to butting faces of both grinding wheels and pressed down in the sockets of the inserted element.2. A device for double-sided grinding of flat butting faces particularly small cylindrical ceramic, consisting of at least one pair of spindles, with faces of grinding wheels mounted on the end and pointing towards each other, which grinding wheels are located along one horizontal line, however, the grinding wheels have flat butting faces equipped with an insertion chamfer, and between grinding wheels is located part of circumference of disk supplying the processed objects, equipped on the circumference in evenly spaced sockets, characterised in that both grinding wheels (13, 14) have on the face...<IMAGE>
