The threading machine is a processing device for the outer surface of a cylindrical workpiece.

How does the thread rolling work?
The two identical, twisted thread rolling faces have the same tooth shape as the tooth shape of the bolt thread, and the bolt blank between the two thread rolling plates is threaded when the thread rolling plates move relative to each other.
The threaded plate is machined back and forth with one bolt thread, and the speed is quite high.
The thread rolling is mostly used for small bolt processing.
Summary: The thread rolling is the processing of the outer surface of a cylindrical workpiece.
