Custom Roughing End Mill
Carbide roughing end mills are specifically designed for efficient high-volume material removal. They are primarily used in roughing operations to quickly eliminate excess material from workpieces, providing a flat and accurate reference for subsequent finishing processes. ZLY Cutting Tools can design custom cutting tools tailored to your specific material and drawing requirements.
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.
