Custom Roughing End Mill – Corner Radius Ended
Corner radius roughing end mills are ideal for roughing, and the rounded radius edge will leave a smooth overcut seam when cutting.
Custom Roughing End Mill Reference
Parameter Matching:
- Softer materials such as aluminum and copper: Choose a large helix angle of 35° to 45° (for rapid chip evacuation).
- Harder materials such as cast iron, stainless steel, and alloys: Choose a smaller helix angle of 25° to 30° (to reduce cutting forces).
Select the appropriate coating according to the material:
- Steel/cast iron: TiAlN coating
- Stainless steel: TiCN coating (anti-chip adhesion)
- Aluminum: Uncoated / DLC coating / Nano coating
Recommended Cutting Parameters:
- Spindle Speed (S):
- Cast Iron: 300-800 rpm
- Steel: 200-600 rpm
- Stainless Steel: 100-400 rpm
- Axial Depth of Cut (ap): For roughing, we recommend 1-4 mm to avoid overloading.
