Micro Ball Nose End Mill Selection and Application Notes

Because micro diameter tools have lower cross-sectional rigidity than larger end mills, tool selection and machining conditions should be confirmed carefully before production.

Tool Selection

  • Select only the cutting length required by the machining feature
  • Use the shortest practical tool reach whenever possible
  • Choose 2 or 4 flutes according to chip evacuation and machining operation
  • Select suitable ball radius according to the required surface geometry
  • Match cutting-edge geometry to the workpiece material

Machining Stability

  • Maintain low spindle and toolholder runout
  • Use rigid toolholding and stable workpiece clamping
  • Avoid excessive radial or axial cutting engagement
  • Provide reliable chip evacuation around small features
  • Use suitable cutting parameters for the actual tool diameter
