摘要

PURPOSE: A door device of a machine tool having a dual-hinge structure is provided to improve space efficiency by reducing the occupation of a space as a door is opened and closed on a perpendicular rail. CONSTITUTION: A door device of a machine tool having a dual-hinge structure comprises a first rail(200), a pair of second rails(300), and a dual hinge unit(400). The first rail is placed at the front of the machine tool. A pair of the second rails is placed on both sides of the first rail at a predetermined angle to the first rail. A pair of doors is connected to the first and second rails. The dual hinge unit is placed on the first and second rails with being connected to both sides of the doors in order that the doors respectively move along the first and second rails.
