Zusammenfassung: | PROBLEM TO BE SOLVED: To collectively move a plurality of cutting edges in the crossing direction with the axial direction between a retraction position and a cutting position, and to also adjust an edge position of the cutting edges for finishing processing, in a boring tool having the plurality of cutting edges mutually separated in the axial direction.SOLUTION: A bar 52 is provided with an inclination slider 62 and a movable inclination block 60. Cutting edges 80c, 81c and 100c can collectively move between a cutting position and a retraction position by the movement in the axial direction of the bar 52. When a block position adjusting part 110 is operated by manual operation by an operator or an external device, the movable inclination block 60 is moved in the radial direction, and an edge position of the cutting edge 100c is adjusted.SELECTED DRAWING: Figure 3
【課題】互いに軸方向に隔たった複数の切刃を備えたボーリングツールにおいて、複数の切刃を一括してリトラクト位置と切削位置との間で軸方向と交差する方向に移動可能、かつ、仕上げ加工用切刃の刃先位置を調整可能とする。【解決手段】バー52には傾斜スライダ62と可動傾斜ブロック60とが設けられる。バー52の軸方向の移動により、切刃80c,81c,100cが一括して切削位置とリトラクト位置との間で移動可能とされる。また、ブロック位置調整部110がオペレータによる手動または外部装置により作動させられると、可動傾斜ブロック60が半径方向に移動させられ、切刃100cの刃先位置が調整される。【選択図】図3 |
