Roll threading a journal requires turning the diameter before rolling. Roll threading implies that part volume is a key. In any high-volume production application, the parts require turning to prep for threading. The blazing speed of roll threading can be mirrored with equal speeds in turning the blank. Utilizing a multi fluted indexable hollow mill with 3 or more carbide turning inserts can triple or quadruple turning speeds always utilizing a single pass process. Nothing is faster or more accurate.
Most always, the time saved in turning, more than pays for the tooling costs. It always yields dramatic production cost savings as well as equally dramatic production increases. Not all hollow mills are created equal. Some indeed work better than others and our years of thread rolling experience have given us an edge in identifying the right tool for your application.
