how thread rolling machine works

There are two identical thread rolling surfaces with the same thread profile and the same helix angle as the thread profile of the bolt. The bolt blanks between the two thread rolling plates are threaded out when the thread rolling plates move mutually. The thread rolling board is processed one bolt thread at a time, and the speed is quite high. Thread rolling is mostly used for small bolt processing.
