Zusammenfassung:	To detect early the deterioration of a tapered outer surface of a taper shank of a tool.SOLUTION: A machine tool includes: a tool magazine 3 for storing multiple tools 2; a spindle that selectively holds one from multiple tools 2 stored in the tool magazine 3; a glossiness measuring unit 11 for measuring the glossiness of a tapered outer surface 23a of a taper shank 23 of the tool 2; a deterioration determining unit 12 that determines whether or not the tapered outer surface 23a is degraded based on the glossiness measured by the glossiness measuring unit 11; and a notifying unit 13 that notifies a worker of a deterioration of the tapered outer surface 23a when the deterioration determining unit 12 determines that the tapered outer surface 23a is deteriorated.SELECTED DRAWING: Figure 5 【課題】工具のテーパシャンクのテーパ外面の劣化を早期に発見する。【解決手段】工作機械は、複数の工具２を収納する工具マガジン３と、工具マガジン３に収納された複数の工具２を択一的に保持する主軸と、工具２のテーパシャンク２３のテーパ外面２３ａの光沢度を測定する光沢度測定部１１と、光沢度測定部１１によって測定された光沢度に基づいてテーパ外面２３ａが劣化しているか否かを判断する劣化判断部１２と、劣化判断部１２によってテーパ外面２３ａが劣化していると判断された場合に、テーパ外面２３ａの劣化を作業者に報知する報知部１３と、を備える。【選択図】図５
