Provided is a machine tool for visualizing the state of a ball screw in an easy-to-understand manner, the machine tool comprising: a detection unit that detects at least one detection value of a vibration, a sound, current applied to drive the ball screw, heat, light, and a power value, during a warm-up operation; a feature amount extraction unit that extracts a first feature amount and a second feature amount from the detection value detected by the detection unit; and a display unit that displays, on a plane having a numerical value corresponding to the first feature amount as a first axis and a numerical value corresponding to the second feature amount as a second axis, a point where the detection value is plotted and at least two boundary lines arranged in a contour line manner to express a possibility of a failure occurring in the ball screw.
