PROBLEM TO BE SOLVED: To provide a grinding method for a cylindrical workpiece capable of grinding not only an outer diameter side but also an inner diameter side to a desired dimension without directly measuring the inner diameter side and performing grinding machining in a shorter time using an outer grinding tool, an inner grinding tool and a measurement means capable of measuring the outer diameter side. SOLUTION: The grinding method for the cylindrical workpiece includes: a step for tentatively grinding a part of a machining position of the outer diameter of the cylindrical workpiece W by the inner grinding tool TN, obtaining the position information of the inner grinding tool and measuring a dimension of a portion (WK) tentatively ground by the outer diameter measurement means 60; a step for determining an inner grinding tool tip position, i.e., a position of a radial tip of the cylindrical workpiece in the inner grinding tool based on the position information of the inner grinding tool when tentative grinding is performed and a dimension of the outer diameter of the tentatively ground portion; a step for grinding the inner diameter of the cylindrical workpiece by controlling a position of the inner grinding tool based on the inner grinding tool tip position; and a step for grinding the outer diameter of the cylindrical workpiece including a portion tentatively ground using the outer grinding tool.
