To provide a groove machining device and a groove machining method capable of contributing to improvement of machining efficiency of a rope groove shape while suppressing deformation of the machined rope groove shape, and an elevator provided with the groove machining device.SOLUTION: This groove machining device is configured to: calculate a predicted car height value after the lapse of predetermined time with respect to a car height measurement value after the start of machining; calculate a predicted axial position value and a predicted radial position value corresponding to the calculated predicted car height value from a vibration database; calculate the target position of a machining tool by using the predicted axial position value, the predicted radial position value, and the calculated predicted car height value; and control the position of the machining tool on the basis of the calculation result.SELECTED DRAWING: Figure 2

    【課題】加工後のロープ溝の形状の変形を抑制しつつ、ロープ溝の形状の加工効率の向上に寄与する溝加工装置および溝加工方法と、その溝加工装置を備えたエレベータ装置を得る。【解決手段】溝加工装置は、加工開始以降のかご高さ測定値に対して一定時間経過後のかご高さ予測値を演算し、演算したかご高さ予測値に対応する軸方向位置予測値と径方向位置予測値を、振れデータベースから演算し、軸方向位置予測値と径方向位置予測値とかご高さ予測値を用いて、加工工具の目標位置を演算し、その演算結果に基づいて、加工工具の位置を制御するように構成されている。【選択図】図2
