PTG Tools - Thread Rolling Dies
Since flat dies with sharp corners on the runout threads generate stress concentration areas that result in fatigue cracks on the thread rolled screw, PTG brands offer controlled radiused root runout (RRO) as a standard feature on all dies. With RRO, the smooth radius in the thread root continues to the point at which the thread blends in the screw shank. This radius distributes stresses ...
Threading (manufacturing) - Wikipedia
Threading is the process of creating a screw thread.More screw threads are produced each year than any other machine element. There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such as 3D printing); or ...
