Further, instead of the plug member 23, for example, a resin or the like may be filled so that the gap between the first flow path FC1 and the second flow path FC2 is closed on the tip 10a side with respect to the fluid outlet portion 15.
- the electrode 11 may be exposed by forming a portion where the insulating layer 12 is not provided on the outer peripheral surface of the electrode 11 at a position 180 degrees apart from the fluid outlet 15 around the axis O.
- the reaction force F current is passed between the exposed portion of the outer peripheral surface and the inner surface of the machining hole 101.
- electrolysis of the machining hole 101 can be promoted on the side where the tool body 10 is curved, and the efficiency of forming the bent hole can be improved.
- the electrolytic processing tool 3 needs to be rotated. There is a possibility that the tip 10a of the main body 10 vibrates and the short-circuit frequency at the exposed portion increases.
- the flow path FC is divided into a first flow path FC1 and a second flow path FC2, and the displacement of the tool body is controlled by controlling the amount of electrolyte W derived from the fluid deriving section 15. Can be easily controlled, so that the frequency of short-circuiting during straight hole drilling can be reduced.

- the second flow path communicates with the fluid outlet portion.

Abstract
Description
本願は、2012年12月12日に出願された特願2012-271436号に基づき優先権を主張し、その内容をここに援用する。
前記工具本体の周方向位置の一部に、前記第二流路を流通する前記電解液を前記工具本体の径方向外側に向かって導出する流体導出部が形成されている。
ここで、流路区画部を工具本体に設け、電極の内側の流路を第一流路と第二流路とに区画したことによって、第一流路と第二流路とに独立して電解液を流通させることが可能となる。また、流体導出部は第二流路に通じているため、第二流路へ流通させる電解液の流量を増減させることで工具本体の流体導出部からの電解液の導出量を調整することができ、工具本体の変位量を容易に調整可能となる。
以下、本発明の第一実施形態に係る電解加工システム1について説明する。
電解加工システム1は、被加工材100に加工孔101を形成するための装置である。本実施形態では一例として、被加工材100はガスタービンのタービン翼であり、被加工材100の加工孔101は、タービン翼を冷却するための冷却孔となっている。
以下、加工孔101を有する被加工材100の製造方法、即ち、孔空き部材の製造方法を交えて説明する。
図2A及び図2Bに示すように、電解加工工具3は、被加工材100に加工孔(タービン翼の冷却孔)101を電解加工により形成するものである。電解加工工具3は、電極11、及びこの電極11を外周から覆う絶縁層12を有して、全体として筒状をなす工具本体10を備えている。
このリブは図示しないが、例えば、電極11の内周面11aから軸線O方向、周方向に間隔をあけて径方向内側に向かって突出して設けられ、内筒部材17の外周面17aを固定する。
従って、流体導出部15は、第二流路FC2と工具本体10の外部とを連通している。
次に、本発明の第二実施形態に係る電解加工システム21について説明する。
なお、第一実施形態と共通の構成要素には同一の符号を付して詳細説明を省略する。
本実施形態では、内筒部材17に設けられて、第二流路FC2を工具本体10の先端10aで閉塞する栓部材23を、工具本体10がさらに有している。
例えば、流体導出部15とは軸線O回りに180度離間した位置における電極11の外周面に、絶縁層12を設けない部分を形成して電極11を露出させてもよい。このようにすることで、反力Fを受けて工具本体10が湾曲した際には、この外周面の露出部分と加工孔101の内面との間で通電する。このため、工具本体10が湾曲した側で加工孔101の電解を促進でき、曲がり孔の形成の効率化を図ることができる。
