Super Finishing for Cylindrical Rollers and Needles

Super Finishing for Cylindrical Rollers and Needles

Product/User Benefits               

  • A/O vitrified bond: better material removal, mainly for the first station(s)
  • SIC vitrified bond: better surface quality, mainly for the last station(s)
  • Mixture of A/O and SIC vitrified bond: combines advantage of both (surface finish and material removal)
  • A/O resin bonded with graphite: for very low surface finish, mainly for last station of multi-station machines
  • Special products: with paraffin or sulphur impregnation for higher material removal rates


Super Finishing of cylindrical rollers and needles with multi-station machines

General Information

The Super Finishing is the final operation for the OD of the rollers and needles.  All requirements like roundness, wave, form and surface finish have to meet precision tolerances.


  • Muti-Station Super Finishing Machines

The roller and needles are supported by steel rolls, while a set of stones oscillates on the top of the components
