Claims (1)
在に装着すると共に該クロスレールに主軸頭を水
平方向に移動自在に装着してなる門形工作機械に
おいて、前記主軸頭の位置決装置、主軸先端及び
その間の温度分布の折曲点付近にそれぞれ温度測
定器を設けると共に前記門形フレームの中間高さ
付近に温度測定器を設けることにより、前記主軸
頭全体の熱変位及び前記門形フレームの熱変位に
よる前記位置決装置の位置変化の双方を推定する
ことを特徴とする熱変位補正装置。 In a portal type machine tool, a horizontal cross rail is mounted on a portal frame so as to be movable up and down, and a spindle head is mounted on the cross rail so as to be movable in a horizontal direction. By providing a temperature measuring device near the bending point of the temperature distribution between them, and also providing a temperature measuring device near the intermediate height of the portal frame, the thermal displacement of the entire spindle head and the thermal displacement of the portal frame can be changed. A thermal displacement correction device characterized by estimating both the positional change of the positioning device caused by the change in position of the positioning device.
