PROBLEM TO BE SOLVED: To provide a method for grinding a disc part that is applicable to workpieces of different widths by a rotary grinding wheel of a small width for reducing manufacturing cost of a grinding wheel. SOLUTION: The grinding wheel 55 is moved from an inner part 21 positioned at a center of the disc part 13 to an outer part 22 positioned diametrically outward by feeding f to move (for traverse cut) as shown with an arrow 3. Rotation speed (rotation number n) of the disc part 13 is controlled in such a way that circumferential speed V of the disc part 13 as measured at a width center 56 of the grinding wheel 55 is constant.
