Step Tungsten Carbide End Mill 4 Flutes Forming CNC Milling Cutter
For Aerospace
Introduction:
Our precision Step Tungsten Carbide End Mill with 4 flutes is
specifically engineered for aerospace component manufacturing. This
high-performance forming cutter features an advanced step design
that enables simultaneous roughing and finishing operations in
titanium alloys (Ti-6Al-4V), Inconel, and aerospace-grade aluminum.
Manufactured from ultra-fine grain tungsten carbide with
micro-grain structure, this tool delivers exceptional accuracy
(±0.005mm) and surface finishes (Ra 0.2-0.4μm) critical for flight
components.
Features:
Special step geometry for efficient material removal and fine
finishing
4-flute design optimized for vibration-free machining
Aerospace-grade micro-grain carbide substrate (8% cobalt)
TiAlN/AlCrN coating options for heat resistance (up to 900°C)
Precision ground cutting edges with <0.003mm runout
Available in diameters from 3mm to 16mm
Custom lengths and neck designs available
Advantages:
✓ 30% faster metal removal than standard end mills
✓ Extended tool life - 4X longer than conventional carbide tools
✓ Reduced machining time by combining operations
✓ Excellent chip evacuation in deep pocket milling
✓ Maintains dimensional accuracy in thin-wall structures
Applications:
Turbine blade root forms and fir-tree slots
Structural component pockets and contours
Wing spar machining
Landing gear components
Engine mount interfaces
Avionics housing features
