Features & Benefits
Thread rolls, spare parts and repair service for most thread rolling heads also available
Rolled threads are produced in a single pass at speeds far in excess of those used to cut threads
The thread is formed by the axial flow of material in the workpiece. The grain structure of the material is not cut, but is distorted to follow the thread form. No chips or swarf should be produced
The resultant thread is very much stronger than a cut thread. It has a greater resistance to mechanical stress and an increase in fatigue strength. Also the surface is burnished and work hardened. There are no pits at the crest or cracks at the core, which often occur with cut thread
