<P>PROBLEM TO BE SOLVED: To provide a cutting device capable of enhancing reliability and maintenance properties in a tool displacement mechanism in which a working tool is displaced along a shaft tool direction of the working tool to a workpiece. <P>SOLUTION: In the cutting device 100, a working field WF as a closed space formed by partitioning a part of a casing 101 by a region blocking wall body 105 is formed. A workpiece holding part 106 holding a workpiece WK is provided in the working field WF. A tool holding body 111 detachably holding the working tool 110 in such a state of penetrating a tool guide wall body 118 which constitutes a part of the region blocking wall body 105 is provided in an upper part of the workpiece holding part 106. The tool holding body 111 is slidably fitted to a sleeve body 119 slidably fitted to a through-hole 118a formed at the tool guide wall body 118 and is supported by a movable base 113 of a working head 112 disposed in a working head inner part region HF in a state that the sleeve body 119 is pulled by a spring 120. <P>COPYRIGHT: (C)2013,JPO&INPIT |
