Honing process

  • Parameters before honing

According to workpiece’s demands, we suggest twice honing to complete

  • :Stock for removal:06-0.08mm/Dia;
  • :Roundness:≤015mm;
  • : Straightness:≤02mm;
  • :Roughness:Ra2um;
  • :Ensure all positions related to the hole, as honing does not improve the position accuracy of the hole.
