Process Thread Rolling

Thread and Profile Rolling belong to the chipless forming procedure. This technology is used for producing threads, worm gears and serrations on the outside of a round work piece which is axially symmetric. On the sur- face of the work piece a certain profile will be formed.

This is an extremely efficient chip - less forming process saving steel because of the absence of chips on the one hand. On the other hand you will receive an increase in the surface hardness . Based on the uninterrupted structure in the cold formed material you will receive a work piece of in- creased tensile strength.
