PROBLEM TO BE SOLVED: To provide a machine tool allowing a rotating body to be operated by readily setting the rotational speed and direction of rotation thereof by use of a manual pulse generator. SOLUTION: A control device 800 of a machine tool 1 includes a first determination unit 850 determining an amount of rotation, rotational speed, and direction of rotation of a rotary handle based on a pulse signal generated by rotation of the rotary handle at a manual pulse generator, and a second determination unit 860 determining which of position control and rotational speed control is selected by selection of an axis through an axis selector switch, based on a signal generated by an axis selection signal generator at an operation device including the manual pulse generator. When a determination is made that position control is selected, the control device 800 controls the amount and direction of travel of a spindle based on the amount of rotation and direction of rotation of the rotary handle. When a determination is made that rotational speed control is selected, the control device 800 controls the rotational speed and direction of rotation of a table based on the rotational speed and direction of rotation of the rotary handle.
