PURPOSE:To simultaneously grind both end faces of a flange part and both cylindrical parts, in a grinding machine used for grinding a cylindrical article having the flange part, by using a grindstone device of shape in which two conical beds are jointed in their bottom surfaces. CONSTITUTION:A work 1, having a flange part and coaxial cylindrical parts in both ends of the flange part, is supported by a regulating wheel 15 and supporting plate 18, and positioned in the axial direction by a stopper 16. The work 1 is rotatively driven by the regulating wheel 15, and end faces of the flange part and the cylindrical parts are simultaneously ground by grinding wheels 25, 26. The grinding wheels 25, 26 are formed to a shape, in which two conical beds are jointed in their bottom surfaces, and provided on grinding wheel slides 27, 28 to perform cutting in the ridge line direction of the jointed surface. |
