EDM Tungsten Copper Electrode
EDM tungsten copper electrode is tool electrode used in Electrical Discharge Machining (EDM) to erode workpiece material and form complex cavities and precision contours. CTIA's tungsten copper electrode uses the electro-erosion caused by pulsed discharges to machine workpieces. It features minimal electrode wear and excellent edge retention, which helps reduce edge wear and contour rounding. It is suitable for the finishing of cemented carbide molds, micro-holes and grooves, and high-precision cavities.
1.Features of CTIA's EDM Tungsten Copper Electrode
(1) Low Wear and Good Edge Retention: During discharge, the tungsten skeleton helps maintain electrode shape, reducing edge rounding and contour wear and improving dimensional accuracy of complex cavities.
(2) High-Temperature Resistance and Ablation Resistance: Tungsten has high melting point, and the copper phase helps conduct heat, reducing electrode wear caused by local heat accumulation, suitable for repeated-discharge machining environments.
(3) Electrical and Thermal Conductivity for Balanced Machining Efficiency: Tungsten copper has good electrical and thermal conductivity, helping conduct pulse current and diffuse discharge heat, balancing electrode wear and material removal efficiency.
(4) High strength, suitable for slender electrodes: Tungsten-copper typically has higher mechanical strength than pure copper and can be machined into slender rods, narrow grooves, and microstructured electrodes, making it suitable for deep-hole, micro-hole, and complex cavity machining.
(5) Different Material Ratios for Different Priorities: CuW70 balances material removal efficiency and electrode wear, suitable for conventional precision EDM; CuW80 has higher hardness, suitable for conditions with higher requirements for wear resistance and shape retention.
2.Applications of CTIA's EDM Tungsten Copper Electrode
(1) Mold Manufacturing: Used for machining complex cavities, irregular holes, and fine contours in cemented carbide molds, reducing electrode edge wear and improving cavity dimensional accuracy.
(2) Precision Parts Machining: Used for machining micro-grooves, narrow ribs, sharp corners, and complex 3D structures, reducing electrode contour wear and improving the forming accuracy of microstructures.
(3) Cemented Carbide Machining: Used for machining deep holes, micro-holes, and irregular structures in cemented carbide molds, wear-resistant parts, and tools, reducing electrode wear and improving the consistency of hole shapes and contours.
(4) Micro-structure manufacturing: Used for machining microfluidic chip molds, microstructural inserts, and precision cavities; it preserves the dimensions and edges of microstructures to meet fine-forming requirements.
(5) Aerospace manufacturing: Used for EDM machining of complex structures in titanium alloy and nickel-based superalloy parts; it minimizes the impact of electrode wear on machining contours and dimensional accuracy.
