The Industry Leader in Thread Rolling Solutions
Our Cold Root Roll System is manufactured to hold extremely tight tolerances with polished surfaces to produce mirror-like finishes on your part.
When burnishing, the pressure generated by the rolls exceeds the yield point of the part surface at the point of contact, resulting in a slight deformation on the surface of the work piece.
Since most machined surfaces consist of a series of peaks and valleys of inconsistent height, the deformation created by roller burnishing displaces the material from the peaks into the valleys creating a mirror like finish with a tough, work-hardened and wear resistant surface.
