To provide a positioning device for process machine which can easily position the center of a processing object member on the center of a rotary table with high accuracy with a simple mechanism.SOLUTION: An upper rotary table for fixing a processing object member W is attached in a relatively displaceable manner to a lower rotary table 12. Two pushing mechanisms 16U, 16L for relatively displacing the upper rotary table with respect to the lower rotary table 12 are point-symmetrically arranged with respect to a lower rotary table center C2. Each coordinate for any three points P1, P2, P3 of the outer periphery of the processing object member W is acquired by a probe 18a, an eccentric distance L between the lower rotary table center C2 and a processing object member center CW and a deflection angle θ of a symmetric axis SL with a virtual center axis CL of the two pushing mechanisms 16U, 16L as a reference are calculated. The lower rotary table 12 is rotated by θ by a spindle 13a and the upper rotary table 11 is relatively moved on the lower rotary table by L by the two pushing mechanisms 16U, 16L.SELECTED DRAWING: Figure 6 【課題】簡易な機構で精度良く被加工部材の中心を回転テーブルの中心に容易に位置決めすることが可能な加工機用位置決め装置を提供する。【解決手段】被加工部材Ｗを固定する上回転テーブルを下回転テーブル１２に対し相対変位可能に取り付ける。上回転テーブルを下回転テーブル１２に対し相対変位させる２台の押込み機構１６Ｕ,１６Ｌを下回転テーブル中心Ｃ２に対し点対称に配置する。プローブ１８ａによって被加工部材Ｗの外周の任意の３点Ｐ１,Ｐ２,Ｐ３についての各座標を取得し、下回転テーブル中心Ｃ２と被加工部材中心ＣＷとの間の偏心距離Ｌと、２台の押込み機構１６Ｕ,１６Ｌの仮想中心軸ＣＬを基準とした対称軸ＳＬの偏角θをそれぞれ算出する。スピンドル１３ａによって下回転テーブル１２をθだけ回転させ、２台の押込み機構１６Ｕ,１６ＬによってＬだけ上回転テーブル１１を下回転テーブル上を相対移動させる。【選択図】図６
