In the world of EDM (Electrical Discharge Machining), the quality of your Tungsten Copper electrode determines the success of your mold. The SAMHO WCu Ball Nose Series is designed to handle the unique density and abrasiveness of tungsten copper, delivering stable, high-accuracy performance where standard carbide tools fail.
Advanced Technical Features
- Sharp 2-Flute Geometry for Low Cutting Resistance
Tungsten copper is “soft-yet-tough,” which can lead to heat buildup and tool dragging. Our optimized dual-flute design features:- Enhanced Chip Evacuation: Prevents chip welding and ensures smooth flow
- Minimized Cutting Forces: Maintains stability in delicate micro-machining and thin-walled electrode features
- Ball Nose Profile Optimized for 3D Surface Finishing
The hemispherical cutting edge is ideal for freeform surfaces, inner corner transitions, and sculpted features:- “Mirror-Like” Finishes: Reduces need for manual polishing or EDM touch-ups
- Geometric Consistency: Vital for high-tolerance mold inserts and precision connectors
- Ultra-Fine Grain Carbide for Extreme Abrasion Resistance
Tungsten copper’s dense grain structure is abrasive on cutting edges. SAMHO uses a premium heat-resistant, ultra-fine grain carbide substrate:- Exceptional Edge Integrity: Maintains sharpness over long production cycles
- Chipping Resistance: Handles interrupted cuts and complex geometries
- 5-Axis CNC Precision with ±0.01 mm Tolerance
Every tool is manufactured using advanced 5-axis CNC grinding technology to ensure perfect concentricity and repeatable accuracy—essential for micro-structures where even a micron matters
Target Applications & Industries
- EDM Electrode Manufacturing: High-precision milling of WCu electrodes for aerospace and automotive molds
- Micro-Mold Making: Intricate 3D cavity milling in dense non-ferrous alloys
- High-Tolerance Components: Precision parts for electrical contacts and thermal management
Professional Usage Recommendations
- Cooling Strategy: Optimized for dry machining or MQL (Minimum Quantity Lubrication) to manage thermal stability and prevent edge oxidation
- Setup Rigidity: For ultra-micro diameters (R0.1–R0.5 mm), use high-precision hydraulic or shrink-fit holders to minimize runout and prevent tool breakage
- Long Reach Options: For deep-cavity applications, check our Long Neck Series for superior clearance without sacrificing rigidity
