| 摘要 |
The present invention relates to a mounting device adapted for a cutting tool in which, by screwing a tightening screw into a screw hole of an insert mounting seat of a tool body through a through hole of a cutting insert, the cutting insert is detachably mounted on the insert mounting seat. A central axis of the screw hole is inclined with respect to a normal direction of a bottom wall surface of the insert mounting seat. When the cutting insert is placed on the insert mounting seat, on a virtual plane defined so as to expand the bottom wall surface, a central axis of the screw hole is shifted from the central axis of the through hole to the side of one of two side wall surfaces of the insert mounting seat. On the virtual plane, an axis shift direction of the central axis of the screw hole and an inclination direction of the central axis of the screw hole are different. |
