| Outline of Final Research Achievements |
In order to realize high-precision machining of ultra-precision parts with fine shapes, which is increasing in the medical, electronics, automotive, and other fields. This research project focused on the development of a rotating mechanical system, namely spindle system, to be mounted on a machine tool. In particular, the thermal deformation of the spindle caused by changes in the amount of heat generated during machining is directly affect to machining errors. Thus, the temperature and deformation performance of the developed spindle were investigated through experiments and analysis using a three-dimensional analytical model. Furthermore, a reduction of spindle temperature change was achieved using a developed temperature control system.

| Academic Significance and Societal Importance of the Research Achievements |
本研究課題では，3種類の冷却構造を有するスピンドルを開発した．さらに，開発スピンドルに対する基礎実験と3次元モデルによる解析を実施し，スピンドル各部における各種熱的特性を明らかにした．特に，温度変化を予測できるだけではなく，熱変形形態も詳細に明らかにした．一連の検討プロセスは，様々な機械システムの熱的特性を評価する際に利用できると思われる．
さらに，本研究では，独自のフィードバック温度制御システムを用いてスピンドル温度の安定化を実現した．この技術は，スピンドルに限らず様々な機械，電気システム等の温度制御に適用できるものである．
