The invention relates to a laser machine tool comprising a protecting door (3) which can be moved back and forth in an opening and a closing direction. Said protecting door (3) has a protecting element (8) which is installed on one side of said door (3), in the closing direction, and can move towards a door leaf (4) of said door (3) in the opening and closing directions. Said protecting element (8) is provided with an actuation element (10) which is actuated when encountering an obstacle. When such an obstacle is encountered, in addition to the actuation of said actuation element (10), the protecting element (8) is pushed in the direction of the door leaf (4) in order to reduce the risk of injury or damage.
