Zusammenfassung: | To provide a modular boring system that can supply a high-pressure coolant.SOLUTION: A modular boring system includes: a first side lock bolt 19 for detachably connecting a boring head of a tip side with a tool shank of a distal side, and fixing them; a passage connecting member 41 being a member arranged in the tip side from the passage of the tool shank, and having an end large diameter part 42 fitted in a recess 15, a tip small diameter part 43 protruding from the distal side large diameter part 42 into the tip side and fitted in a head passage 34 of the boring head, and a through passage 44 penetrating from the end large diameter part 42 to the tip small diameter part 43 and bringing the passage of the tool shank into communication with the head passage 34; an end seal part 46 for sealing an annular gap between an outer circumferential surface of the end large diameter part 42 and an inner circumferential surface of the recess 15; and a tip seal part 47 for sealing the annular gap between an outer circumferential surface of the small diameter part 43 and the head passage 34.SELECTED DRAWING: Figure 2
【課題】高圧クーラントを供給可能なモジュラーボーリングシステムを提供する。【解決手段】モジュラーボーリングシステムは、先端側のボーリングヘッドと末端側の工具シャンクを着脱可能に接続固定する第1サイドロックボルト19と、工具シャンクの通路よりも先端側に配置される部材であって、凹部15に嵌合する末端大径部42、末端側大径部42から先端側へ突出してボーリングヘッドのヘッド通路34に嵌合する先端小径部43、および末端大径部42から先端小径部43まで貫通して工具シャンクの通路およびヘッド通路34を連通する貫通路44を有する通路接続部材41と、末端大径部42の外周面と凹部15の内周面の環状隙間を封止する末端シール部46と、先端小径部43の外周面とヘッド通路34の環状隙間を封止する先端シール部47とを備える。【選択図】図2 |
