PURPOSE: Door opening structure of a machine tool with a moving point is provided to reduce the door installation space and parts by decreasing the distance between the door and the hinge with moving the center of rotation of the door, and to open the door actively and stably by interlocking two hinge points. CONSTITUTION: A door(18) opens and closes the inlet of a non-processing area(11) by revolving. A hinge bracket is installed in a fixing body formed in the non-processing area, and composed of a hinge guide hole formed along the specific radius of curvature. A door bracket(50) is connected to the hinge guide hole with two hinges(40,41), and fixed to the door. The position track is moved along the hinge guide hole with interlocking two hinges in opening and closing the door with turning. The installation space is reduced by decreasing the distance between the door and the hinge with interlocking the center of rotation.
