精密フライスカッター,あらゆる材料を加工するCNC用の切削工具
A Diamond End Mill is an advanced CNC cutting tool featuring diamond coatings (CVD/PCD) or polycrystalline diamond (PCD) tips. Engineered for precision machining of non-ferrous metals (aluminum, copper), composites (carbon fiber, graphite), and ultra-hard materials (HRCの>45), these tools excel in high-speed, high-efficiency applications where surface finish and tool life are critical.
Key Advantages of Diamond End Mills
1 Unmatched Wear Resistance
- CVD/PCD Coatings (HV8000+): 10x longer life vs. carbide, reducing downtime and tool changes.
- PCD-Tipped Design: Ideal for abrasive materials like graphite and CFRP composites.
2 Ultra-High-Speed Performance
- Supports spindle speeds over 18,000 RPM and cutting speeds exceeding 2,000 m/min.
- Shortens cycle times by 40%+ for aluminum, magnesium, and soft metals.
3 Mirror-Quality Surface Finishes
- Achieves Ra≤0.2μm finishes, eliminating secondary polishing.
- Non-stick surface minimizes built-up edge (BUE) in aluminum alloys.
4 Material-Specific Optimization
- High-Silicon Aluminum: 4-flute nano-diamond coating resists adhesion.
- Hardened Steels (HRC50-65): PCD-tipped tools withstand high cutting forces.
5 Precision Engineering
- Radial Runout ≤0.003mm: Ensures ±0.01mm tolerance for micro-machining.
- Variable Helix Angles: Reduces vibration in 3D profiling operations.
6Cost Efficiency
- Single diamond end mill replaces 3-5 carbide tools, cutting costs by up to 30%.

Selection Guide
1 Material-Specific Recommendations
- Aluminum/Copper: 2-flute CVD-coated mill + MQL lubrication.
- CFRP/FRP: 3-flute PCD mill with wave-edge geometry (prevents delamination).
- Graphite: 4-flute nano-diamond coating + forced oil-mist cooling.
2 Operation-Specific Recommendations
- 溝 加工: ≥4xD flute length, ≤0.005mm perpendicularity.
- Profiling: Variable helix angles to suppress harmonic vibration.
- Roughing: Large-diameter tools at low RPM (maximizes MRR).
3Cooling Strategy Matching
- Flammable Materials (Magnesium): Mandatory oil-mist cooling (MQL).
- General Use: Dry/wet/HSM-compatible options available.
