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
