Tungsten Copper Long Neck Ball Nose End Mill

Struggling with tool interference in deep tungsten copper cavities? The SAMHO WCu Series provides the ultimate reach and precision. Specifically engineered for Tungsten Copper (WCu) alloys, these long-neck ball nose cutters feature optimized geometry for EDM electrodes, complex 3D contours, and micro-mold features.

Extended Reach: Long neck design for deep pocket clearance without tool deflection.

Micro-Precision: Ultra-fine radii starting from R0.1 mm for intricate detailing.

Wear Resistance: Premium ultra-fine grain carbide resists the abrasive nature of WCu.

Accuracy: 5-axis CNC ground to a strict ±0.01 mm dimensional tolerance.

In the manufacturing of complex EDM electrodes and micro-molds, reaching deep features while maintaining surface integrity is a major challenge. The SAMHO Long Neck WCu Series is engineered to provide the necessary clearance and stability for machining dense, abrasive tungsten copper alloys in high-precision CNC environments.


Advanced Technical Features

  • Long Neck Design for Interference-Free Deep Milling
    The specialized extended neck geometry is key for deep cavity and narrow feature access:
    • Access Deep Contours: Perfect for complex 3D electrode geometries and undercuts
    • Maintain Rigidity: Optimized neck-to-diameter ratios ensure stable cutting and minimize vibration, critical for WCu machining
  • Sharp 2-Flute Geometry for Low Cutting Resistance
    Tungsten copper is a dense composite that requires sharp cutting edges to prevent heat buildup:
    • Smooth Chip Evacuation: Rapid removal of debris to prevent chip welding
    • Lower Cutting Forces: Maintains accuracy in thin-walled features and delicate micro-structures
  • Ultra-Fine Grain Carbide for Extreme Wear Resistance
    SAMHO uses a premium ultra-fine grain solid carbide substrate:
    • Exceptional Hardness: Maintains sharp edges even under friction of dry machining or MQL
    • Chipping Resistance: Provides fracture toughness for consistent performance in dense non-ferrous composites
  • Ball Nose Tip for Precision 3D Surface Finishing
    Precision-ground hemispherical tip:
    • Mirror-Like Finishes: Reduces need for post-processing or manual polishing
    • Geometric Consistency: Vital for high-tolerance mold inserts where every micron counts

Comprehensive Model Selection (56 Models)

With 56 specialized models in the SHDLR series, we cover a radius range from R0.1 to R2.0 mm. Whether milling micro-fluidic channels or large-scale electrode cores, SAMHO has the exact size and neck length to fit your CNC requirements.


Target Applications & Industries

  • EDM Electrode Manufacturing: High-precision milling of WCu electrodes for aerospace and electronics
  • Micro-Mold Making: Intricate 3D cavity milling in dense, abrasive non-ferrous alloys
  • Medical & Automotive: Precision profiling of complex, high-tolerance components

Professional Usage Recommendations

  • Cooling Strategy: Use MQL (Minimum Quantity Lubrication) or dry machining with high-pressure air blast to manage thermal stability
  • Setup Accuracy: For micro-diameters (R0.1–R0.5 mm), use high-precision hydraulic or shrink-fit holders to minimize runout and maximize tool life
  • Tip Protection: Use non-contact measuring devices during tool setting to avoid damaging the precision-ground radius

Note:
*Decrease both spindle speed and feed rate proportionally when the milling parameters exceed the machine’s maximum spindle speed;
*Recommend using a non-contact measuring device to avoid damaging the precision tip point.
