Tungsten Copper Electrode in Electro-Erosion Machining
Tungsten copper electrode in electro-erosion machining is tungsten copper composite electrode specially designed for Electrical Discharge Machining (EDM). CTIA's tungsten copper electrode utilizes tungsten to provide high melting point and excellent resistance to arc erosion, while copper ensures good electrical and thermal conductivity. The electrode features low electrode wear, high machining precision, and excellent surface finish, making it particularly suitable for the precision shaping of high-hardness materials such as cemented carbides and die steel.
1.Features of CTIA's Tungsten Copper Electrode in Electro-Erosion Machining
(1) Low Electrode Wear and Good Contour Retention: Tungsten has high melting point, resulting in minimal electrode wear during the discharge process. Sharp edges and complex contours are retained for longer, and the electrode wear rate is significantly lower than that of copper electrodes.
(2) High Machining Accuracy and Dimensional Stability: Suitable for fine contours, sharp corners, and complex cavities, with minimal dimensional deviations and high repeatability.
(3) Good Surface Finish: The surface roughness of the workpiece after machining is low, reducing the amount of subsequent polishing required.
(4) Strong Ablation Resistance: The electrode remains stable even under high-energy, high-frequency discharges and is not prone to end ablation or deformation.
(5) Balanced Electrical and Thermal Conductivity: The copper phase ensures smooth current transmission and rapid heat dissipation; common CuW70 has a conductivity of approximately 42% IACS, while CuW80 has approximately 34% IACS.
(6) Adjustable Composition and Flexible Selection: Different compositions, such as CuW70 to CuW90, can be selected based on the hardness of the material being machined, precision requirements, and material removal rate.
2.Applications of CTIA's Tungsten Copper Electrode in Electro-Erosion Machining
(1) Cemented Carbide Mold Machining: Used for finishing blanking die, wire drawing die and complex special-shaped cavity, with better retention of sharp corner and narrow slot.
(2) Precision Cavity and Deep Slot Machining: Suitable for high-aspect-ratio structures such as deep hole, narrow slit and micro channel, with better chip removal condition.
(3) High-Hardness Conductive Material Machining: Used for piercing and forming of difficult-to-cut materials such as cemented carbide and high-speed steel.
(4) Precision Mold Finishing: After rough machining with copper or graphite to remove allowance, tungsten copper electrode is used for contour finishing, balancing efficiency and final accuracy.
(5) Superhard Material Forming: Suitable for electro-erosion machining of superhard tool and related part such as Polycrystalline Diamond (PCD) and Polycrystalline Cubic Boron Nitride (PCBN).
