Micro Corner Radius 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 corner radius according to the required edge strength and 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
