In the demanding world of aerospace and energy sector machining, the 4-Flute 55° Corner Radius End Mill has emerged as a game-changer for processing heat-resistant alloys like Inconel 718 and Ti-6Al-4V. Engineered to defy the limitations of traditional tools, this cutter combines aggressive geometry, advanced coatings, and shock-resistant design to deliver unmatched performance in extreme conditions.
Precision Engineering for Unyielding Materials
The 55° round nose design ensures optimal chip evacuation while maintaining a sharp cutting edge, critical for minimizing heat buildup in nickel-based superalloys. Key innovations include:
AlCrN/TiSiN Hybrid Coating: Withstands temperatures up to 1,100°C, reducing oxidation wear by 60% compared to standard TiAlN coatings.
Shock-Absorbing Flute Geometry: Asymmetric 4-flute layout disrupts harmonic vibrations during interrupted cuts (e.g., turbine blade root machining).
Over-Center Cutting Edges: Full bottom cutting capability eliminates the need for pre-drilling in closed-pocket operations.
Proven Results in Aerospace Applications
A jet engine component manufacturer reported:
70% Longer Tool Life: From 12 to 20 parts per edge when machining Inconel 718 combustion chambers.
Ra 0.8µm Surface Finish: Achieved without secondary polishing.
35% Faster Feed Rates: Enabled by the 35° helix angle and large core diameter, boosting MRR to 45 cm³/min.
Technical Edge
Submicron-Grade Grinding: ≤2µm edge consistency across all flutes.
0.5mm–16mm Diameter Range: With corner radii from R0.2 to R2.5.
HSK-63A Shank Compatibility: For high-stability machining centers.
For shops battling tough alloys, this end mill is the ultimate fusion of durability and precision.
