REMOTE CUTTING METHOD AND CUTTING DEVICE

To provide a remote cutting method and a cutting device capable of cutting a steel cutting object remotely with no fire.SOLUTION: A remote cutting method has steps of: causing a self-traveling travel body 20 having a direct acting type cutting part 30 cutting with an end mill 32 along a linear rail 35b and a magnet 27 attracted to a steel cutting object to travel to a cutting initiation position with the cutting object attracted thereto; cutting the cutting object linearly along the linear rail 35b from the cutting initiation position with the direct acting type cutting part 30 while the self-traveling travel body 20 is stopped, and returning to the cutting initiation position after cutting; and moving by the length cut by the direct acting type cutting part 30 with the self-traveling travel body 20. The cutting step and the moving step are repeated until the cutting object is cut.SELECTED DRAWING: Figure 1 【課題】鋼製の切断対象物を遠隔かつ無火気で切断できる遠隔切断方法及び切断装置を提供する。【解決手段】本発明の遠隔切断方法は、リニアレール３５ｂに沿ってエンドミル３２で切断する直動式切断部３０及び鋼製の切断対象物に吸着する磁石２７を備えた自走式走行体２０を前記切断対象物に吸着させて切断開始位置まで走行する工程と、前記自走式走行体２０の停止中に前記直動式切断部３０で前記切断開始位置から前記リニアレール３５ｂに沿って直線状に切断して、切断後に前記切断開始位置まで戻る切断工程と、前記直動式切断部３０で切断した長さ分だけ前記自走式走行体２０で移動する移動工程と、を有し、前記切断工程と前記移動工程を前記切断対象物が切断されるまで繰り返すことを特徴とする。【選択図】 図１
