3 Flute Polycrystalline Diamond End Mills OEM / ODM For Aluminum

Custom 3-Flute PCD Relief End Mill Polycrystalline Diamond Undercutting Tool For Aluminum Composites OEM/ODM Available

Introduction:

Our custom 3-flute PCD relief end mill redefines precision undercutting and form milling operations. Engineered with medical-grade polycrystalline diamond (PCD) cutting edges brazed to a high-rigidity carbide body, this specialized tool delivers unmatched wear resistance and micron-level accuracy in machining aluminum alloys, composites, and non-ferrous materials. The unique 3-flute design with customizable relief angles provides optimal balance between material removal rate and surface finish quality for your most challenging applications.

Features:

✔ Advanced PCD Construction

• Diamond layer thickness: 0.3-0.5mm (DA100/DA150 grade available)

• Sub-micron diamond grains (2-25μm) for extreme edge durability

✔ Precision Undercut Geometry

• Standard relief angles: 15°, 30°, 45° (custom angles to ±1°)

• Non-colliding flute design ensures clean undercut profiles

• Radial/axial relief customization for specific workpiece contours

✔ Performance-Optimized Design

• 3-flute configuration reduces harmonics vs 2-flute tools

• Variable helix options (35°/45°) for vibration suppression

• Polished flute surfaces prevent material adhesion

✔ Material-Specific Engineering

• Aluminum version: Sharp rake angles + mirror polish

• Composite version: Reinforced tooth geometry

• Hybrid version: For metal matrix composites (MMCs)

Advantages:

▶ 200-300X tool life vs carbide in silicon aluminum (AlSi12)

▶ Ra 0.2-0.4μm surface finish achievable without polishing

▶ 40% higher feed rates permitted vs standard end mills

▶ ±0.005mm profile tolerance maintained over full tool life

Applications:
