| description | PROBLEM TO BE SOLVED: To provide a machine tool capable of detecting an abnormality caused by extraction of a main spindle.SOLUTION: A machine tool includes a main spindle 42 for rotating a workpiece or a tool, a sensor 47 for outputting a signal corresponding to a rotation angle of the main spindle 42, and a control device for detecting generation of an abnormality in at least either of the main spindle 42 and the sensor, when an electric signal different from a signal outputted during rotation of the main spindle 42 or suspension of the main spindle 42, is outputted from the sensor.SELECTED DRAWING: Figure 2
【課題】主軸が抜き取られたことによる異常を検知することが可能な工作機械を提供する。【解決手段】工作機械は、ワークまたは工具を回転するための主軸４２と、主軸４２の回転角度に応じた信号を出力するためのセンサ４７と、主軸４２の回転中および主軸４２の停止中に出力される信号とは異なる電気信号がセンサから出力された場合に、主軸４２およびセンサの少なくとも一方に異常が発生したことを検知するための制御装置とを備える。【選択図】図２ |
