PROBLEM TO BE SOLVED: To provide a closing method and a closing machine capable of enhancing the positional accuracy of charging a work in an outside diameter chuck. SOLUTION: The closing method for closing a work 9 by holding the cylindrical work 9 by an outside diameter chuck 7, rotating the outside diameter chuck 7 together with the work 9, and pressing the die against the rotating work 9 comprises a step of allowing an inside diameter chuck 8 to hold an inner circumferential surface of the work 9 while the work 9 is abutted on a charge stopper 12 by using the inside diameter chuck 8 to hold the inner circumferential surface of the work 9, a work 9 charging device to move the inside diameter chuck 8 in the Y-axis direction of the work 9, and the charge stopper 12 projecting in a charging path of the work 9, a step of detaching the charge stopper 12 from the charge path of the work 9, and a step of charging the work 9 in the outside diameter chuck 7 by moving the inside diameter chuck 8 in the Y-axis direction of the work 9.
