PURPOSE: A middle door assembly of a machining tool is provided to prevent foreign materials like chips from sticking on a gripper area by opening and closing a middle door if necessary because the middle door is arranged between a machining area and a non-machining setting area. CONSTITUTION: A middle door assembly comprises a middle door(100), a power supply unit(110), a dual guide unit(130), a door frame(101), and a roller unit(150). The middle door opens and closes a machining area and a non-machining setting area. The power supply unit provides power for moving the middle door in the lower part of the middle door. The dual guide unit is arranged in the lower part of the middle door at a position opposite to the power supply unit. The dual guide unit guides the movement of the middle door. The door frame is arranged on the top of the middle door and is fixed in the upper area of a body(102) of a machining tool. The roller unit moves the middle door from the door frame. |
