Thread and Profile Rolling belong to the chipless machining processes. This technology is used for producing threads, splines, grooves, worm gears and serrations on the outside of a round work piece which is axially symmetric. On the SURFACE of the work piece a certain profile will be formed.
This is an extremely efficient CHIPLESS 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 . The uninterrupted structure in the cold formed material increases the tensile strength of the work piece.
