Germany www.hommel-keller.de  
Germany www.ecoroll.de   Roller  burnishing  is  a  forming  process  used  to  generate high-quality,  smooth  surfaces  or  surfaces  with  a  specifi c structure. One or more rollers or balls are used to plastify and form the workpiece’s edge layer. This process is used when a metal component requires a high-quality surface finish  or  when  the  specifi ed  surface  quality  cannot  be achieved reliably with a machining process. The process is described in VDI standard 2032, which also clearly explains the differences between roller burnishing and the rolling process. In roller burnishing, when the compressive stress that occurs  at  the  contact  point  between  the  roller  burnishing tool  and  the  workpiece  surface  exceeds  the  workpiece’s yield  strength,  plastic  deformation  results.  The  rough- ness  peaks  are  pressed  down  in  nearly  a  vertical  direc- tion into the surface and as a result the material fl ow fi lls the  roughness  valleys  from  below  (Fig.  1).  The  resulting smooth surface occurs due to the fl ow of the entire surface near the material’s edge layer, not because the roughness peaks are bent into the surface or fl attened (a widely held, but false assumption).
