Burnishing rolls are manufactured holding 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.
How to Order Burnishing Rolls
When placing an order or requesting a quote, please have the following information available:
- Make and model of thread rolling attachment
- Style of thread roll (i.e. D-1, DR-1, C-1, etc.)
- Size and pitch of thread to be rolled, including dimensional tolerances if other than standard
- Length of thread on part
- Material to be rolled
- Is thread next to collet or cut off side
- Print of part to be rolled
Note:
- Special rolls may require a sample part or more detailed specifications.
- Some rolls require a special calculation to figure the work face on the roll.
