Unlocking the efficient machining of aerospace high-temperature alloys by ceramic milling cutters
High-temperature alloys (e.g., GH4169) are critical for aircraft engines due to their exceptional heat/ocean-corrosion resistance. Yet their high hardness, toughness, and low thermal conductivity pose extreme machining challenges.
Ceramic milling tools deliver a breakthrough:
- 15–20X higher efficiency vs. conventional tools
- 5X longer tool life than solid carbide counterparts
Ceramic milling tools: Product Advantages
1. High-Feed Cutting Edge Design
- Enables aggressive material removal rates
- ↑ 15–20X productivity in superalloy milling
2. Full SiAlON Ceramic Construction
- Superior heat/wear resistance at 400–800 m/min cutting speeds
- 5X lifespan over solid carbide tools
3. Vibration-Reducing Geometry
- Variable pitch design minimizes chatter
- Optimized chip evacuation prevents workpiece damage
