Claims

[Scope of utility model registration request]

An arm rotatably supported around a rotation axis on a headstock of a machine tool, a drive device connected to the arm to rotate the arm, and an elastic member configured to be elastically deformable with respect to the arm. a sensor arm connected through the sensor arm, a detection device attached to the tip of the sensor arm to detect the tool cutting edge position, and a detection device attached to the base end of the sensor arm and supporting the workpiece. A cutting edge position detecting device comprising: a stopper that determines the rotational position of the sensor arm by abutting the chuck so that the bottom thereof is brought into close contact with the chuck by elastic deformation of the elastic member.
