Tungsten copper grinding wheel electrode
Tungsten copper electrodes are mainly used for electrospark machining (EDM) PCD tools, namely disc EDM (Disc Erosion Machining). This process is different from traditional mechanical grinding. Instead, it uses electric spark discharge to erode PCD materials layer by layer to achieve the purpose of precision machining tools.
Copper Tungsten Electrode (Cu-W) is a composite electrode made of highly conductive copper (Cu) and highly wear-resistant tungsten (W). It combines the high melting point and wear resistance of tungsten with the excellent conductivity of copper, making it an indispensable consumable when processing polycrystalline diamond (PCD) tools.
Features of tungsten copper erosion wheel electrodes
High wear resistance: Tungsten increases electrode life, reduces wear and improves processing stability.
Excellent conductivity: Copper ensures uniform discharge and improves processing accuracy.
Low thermal expansion coefficient: The electrode has good dimensional stability, ensuring processing accuracy and consistency.
Suitable for high-precision processing: Especially suitable for PCD tool edge processing, which can obtain sharp and uniform cutting edges.
Applications of PCD Eletrode
PCD end mills (right angle and rounded corners), PCD twist drills, PCD countersink drills, PCD reamer, PCD countersink reamer, PCD step tool, PCD woodworking tool (mixed slot tool), PCD profile cutting tools
