BURNISHING TOOLS MANUFACTURED BY ELLIOTT TOOL TECHNOLOGIES
Burnishing is the best way to improve a surface finish, enhance part quality and eliminate costly finishing operations. Eliminate secondary operations, improve surface finish and save time and money with Elliott burnishing tools.
Our team has worked with thousands of different applications. If you have a question or are wondering if your application is a good fit for burnishing, contact us here.
Burnishing is a chipless machining method which cold works the metal without cutting or abrading the surface.
It removes no metal but rather compresses, or “irons-out” the peaks of a metal surface into the valleys, generating a dense and uniform surface.
Roller burnishing improves surface finish and results in dimensional accuracy.
The cold working condenses the grain structure of metal, producing an increase in surface hardness from 50% to 100%, within a penetration of .010” to .030” on the part’s surface.
In roller burnishing, the material is elastically deformed to a given depth below the surface. The result is compressive stresses at the surface. In turn, this increases the resistance of the material to fatigue failure because any external forces must first overcome these residual stresses.
LOW MICROINCH FINISH
Produces a 4 to 8 Ra surface finish in one pass.
Improves surface irregularities and tool marks.
Burnishing is a repeatable and consistent process.
Fast cycle times – measured in seconds, not minutes!
Multi-roll burnishing tools produce accurate sizing in .0001″ increments.
Roller burnishing in 25% size improvement in steel and up to a 50% improvement in high ductility materials.
Eliminates secondary machines and set ups.
Eliminates secondary processes such as grinding, honing and polishing.
Elliott burnishing tools feature long lasting and replaceable wear parts, reducing total cost over the life of the tool.
Burnishing is effective for many different part configurations.
Suitable process for a variety of metals – all ductile metals can be burnished!
