Claims

[Scope of utility model registration request]

In a joint grinding device that performs grinding while splicing a long screw in the middle, there is a device main body that is rotatably supported on the grindstone side by an angular range corresponding to the screw lead angle, and a threaded workpiece on the device main body. a position measuring part having a tip formed with a spherical contact that is supported movably along the radial and axial directions and that contacts the thread; and a position measuring part that is configured to press the contact of the position measuring part against the thread. A thread joint grinding device characterized in that it is provided with an urging means for urging, and a detection and display means for detecting and displaying the engagement state between the thread and the contact.
