(Note: Precise parameters ensure stability in high-temp alloy machining)
Why Our Solutions Worked
1. Material-Specific Tool Design
- Case 1: Specialized flute geometry for efficient chip evacuation in deep holes.
- Case 2: Optimized edge preparation for Inconel 718’s work-hardening properties.
2. Cooling Integration
- Internal cooling (Case 1) prevented heat accumulation in 90 mm deep holes.
- Emulsion cooling (Case 2) controlled thermal stress on the tool.
3. Parameter Precision
- Balanced RPM/feed ratios maximized tool life while maintaining productivity.
Conclusion
These proven results demonstrate our tools’ capabilities in extreme conditions:
▶Achieved 432 meters of cumulative drilling depth in hardened C70S6 steel at high efficiency.
▶Maintained stable milling performance on aerospace-grade Inconel 718 at 113 m/min cutting speed.
