In the high-stakes world of aerospace manufacturing, where micron-level precision defines success, the Ultra-Thermal Shrink Fit Holder emerges as a game-changer. Designed to clamp cylindrical carbide and HSS tools with h6 shank accuracy, this holder leverages advanced thermal dynamics to deliver unmatched rigidity and runout control, even at 30,000 RPM.
Core Innovations
Special Heat-Resistant Steel Alloy: Forged from ISO 4957 HNV3 steel, it withstands 800°C induction heating cycles without structural degradation.
Submicron Concentricity: ≤0.003mm TIR (Total Indicated Runout) ensures mirror finishes on titanium turbine blades.
Dynamic Balancing Mastery: Certified to ISO 21940-11 G2.5, achieving <1 gmm imbalance at 30k RPM – critical for 5-axis contouring of Inconel 718.
Technical Breakthroughs
4-Screw Balancing System: Extended models feature radial screws to fine-tune balance post-shrinking, compensating for tool asymmetry.
Cryogenic Treatment: Post-machining deep-freeze (-196°C) stabilizes molecular structure, reducing thermal drift by 70%.
Nano-Coated Bore: TiSiN coating prevents material adhesion during high-frequency heating/cooling cycles.
Aerospace Case Study
A jet engine OEM machining compressor disks reported:
Ra 0.2µm Surface Finish: Eliminated post-mill polishing.
Tool Life +50%: Reduced vibration extended carbide end mill lifespan.
0.001° Angular Accuracy: Maintained over 8-hour shifts.
