The present invention provides a honing tool device. According to the present invention, cutting processing precision can be improved by minimizing the vibration of a cylinder and a honing member when an inner surface of a cylinder bore is cut. The present invention includes a spindle head section that is provided to be vertically lifted and lowered along a frame section in which an operation space is formed and has a hollow spindle rotatably connected to a central portion; a honing frame that is connected to the spindle and integrally rotates; an expansion chamber section that is formed in a central portion of the honing frame to be connected to the hollow of the spindle and is provided with a lifting protrusion, an inclined surface being formed along an outer circumference therein; and a plurality of expansion arm sections that are radially arranged in the honing frame and are arranged through the honing frame so that respective inner side ends thereof are in contact with the lifting protrusion, a honing member being mounted on an outer side end which expands outside during the lifting of the lifting protrusion, in which the expansion arm sections are arranged so that one of included angles between one of the expansion arm sections and the adjacent expansion arm section differs from one of the other included angles. |
