Zusammenfassung:	To provide a machine tool for automation of a workpiece needing a phase determination.SOLUTION: A machine tool has various drive units for carrying out the prescribed process by a tool to a gripped workpiece, and a controller controlling the drive of the above drive units. Besides, a phase-determining chuck fixture is assembled to a work table provided to a spindle in the machine tool. The chuck fixture comprises a chuck device (a pair of swing arms 31, 32) for pressing the workpiece on a seating surface by a hydraulic actuator, and a phase determination device (the first and second phase determination blocks 33, 34) for pinching a protrusion of the workpiece by the hydraulic actuator.SELECTED DRAWING: Figure 2 【課題】位相決めが必要なワークに対する自動化のための工作機械を提供すること。【解決手段】把持したワークに対して工具による所定の加工を実行するための各種駆動装置と、前記駆動装置の駆動を制御する制御装置とを有し、スピンドルに設けられたワークテーブルに、油圧アクチュエータによってワークを着座面に押し当てるチャック装置（一対のスイングアーム３１，３２）と、油圧アクチュエータによってワークの突出部を挟み込む位相決め装置（位相決め第１ブロック３３、位相決め第２ブロック３４）とを備えた位相決めチャック治具が組み付けられた工作機械。【選択図】図２
