Tungsten Copper Alloy in PCD Electrode
Tungsten copper alloy in PCD electrode is tungsten-copper composite material specifically designed for Electrical Discharge Machining (EDM) of Polycrystalline Diamond (PCD) cutting tools. CTIA's tungsten copper PCD electrodes utilize tungsten to provide high melting point and excellent resistance to arc erosion, while copper ensures good electrical and thermal conductivity. And the electrode features low electrode wear, good contour retention, and high machining accuracy, making it particularly suitable for edge forming, contour machining, and dressing of PCD cutting tools.
1. Features of CTIA's Tungsten Copper Alloy in PCD Electrode
(1) Low Electrode Wear and Excellent Contour Retention: Tungsten has high melting point, so electrode wear during pulse discharge is primarily due to the evaporation of the tungsten phase. Under high-energy discharge conditions, the retention of edges and cutting-edge contours is significantly better than that of low-tungsten materials.
(2) High Machining Precision and Dimensional Stability: Suitable for machining fine cutting edges and complex shapes, with minimal dimensional deviations and high repeatability.
(3) Excellent Surface Finish, Minimal Post-Processing: The surface quality of PCD tools after machining is high, requiring minimal subsequent polishing or dressing.
(4) Strong Ablation Resistance and Resistance to Molten Droplet Adhesion: The electrode remains stable under high-energy discharge, making it less prone to end ablation or molten droplet adhesion.
(5) Balanced Electrical and Thermal Conductivity for More Stable Machining: The copper phase ensures smooth current transmission and rapid heat dissipation, resulting in a more stable machining process.
(6) Adjustable Composition for Flexible Selection: CuW75 is suitable for fine edge finishing with stable discharge; CuW80 is suitable for roughing operations with a higher margin of resistance to ablation.
2. Applications of CTIA's Tungsten Copper Alloy in PCD Electrode
(1) PCD Tool Edge Forming: Used for the precision forming of PCD tool edges, ensuring good contour retention and reducing edge collapse and chipping.
(2) PCD Tool Contour Machining: Used for EDM of complex contours and irregular tool edges.
(3) PCD Tool Dressing: Used for dressing and re-machining tool cutting edges to extend tool life.
(4) PCD and Cemented Carbide Composite Cutting Edge Forming: Used for EDM in the interface area of composite inserts.
(5) Dressing of PCD Wire Drawing Dies and Nozzle Bores: Used for pre-finishing EDM of small-diameter internal bores in rotary bodies; the continuous heat conduction of the copper phase helps control electrode overheating.
