PROBLEM TO BE SOLVED: To provide a cylinder grinding method and a device automatically grinding a cylinder without receiving a specially large grinding load when grinding projection parts irregularly formed in the axial direction of a work with a straight trunk part, for example, an ingot. SOLUTION: This method includes: to set an upper limit set value showing a grindable maximum diameter value, a lower limit set value showing a final diameter value targeted by the cylinder grinding, and a single or a plurality of intermediate set values set between the upper limit set value and the lower value set value and showing a diameter value determining grinding conditions of a partial grinding; and to grind the cylinder by combining the partial grinding and the straight trunk part grinding relative to the work with the straight trunk part based on the set values. This method measures the diameter of the work along the axial direction, compares the measured diameter value with the set value, determines the necessity/non-necessity of the partial grinding to the work based on the comparison result and a grinding procedure, and grinds the cylinder according to the determined grinding procedure so that the work is formed into the lower limit set value.
