Products Description
Copper tungsten erosion discs also known as electrodes for erosion, or erosion electrodes, CuW alloy discs. As very high melting point of tungsten, Copper tungsten erosion discs have very long service life comparing to copper or graphite electrodes. Main CuW erosion wheel benefits are high wear resistance, outstanding surface quality, great machinability.
Copper tungsten erosion discs are mostly used with Walter, Vollmer, Lach, Enokida and other EDM machines. They are also called PCD electrodes, copper tungsten electrodes, electrodes for EDM machines, tungsten copper EDM electrodes.
features
High Electrical Conductivity: Thanks to the copper content, high-frequency electricity is transferred with efficiency and stability from the EDM generator to the workpiece, enabling powerful erosion processes.
Excellent Thermal Conductivity: It removes heat from the spark gap and minimizes thermal damage, micro-cracking, and graphite formation in PCD/PCBN materials.
High Density & Fine Microstructure: The dense, uniform structure bears stringent requirements ensuring minimal electrode wear, thus prolonging service life while lowering machining costs. It also helps maintain precise shapes in tools made of PCD/PCBN, enhancing surface finish and sharp edges.
Superior Wear Resistance: Due to high tungsten content, strong erosive wear resistance provides the electrode with sustained fidelity of shape over long machining cycles.
High Melting Point: It provides the copper-tungsten electrode with the ability to endure high temperatures during the machining of hard materials.
Lower Thermal Expansion: Dimensional stability enables consistency and precision in machining.
applications
Creating New Tools:
After brazing PCD or PCBN segments, these discs accurately contour the material to intricate cutting geometry configurations. They create chip breakers or particular edge preparations, accomplishing final form precision on inserts, milling cutters, routers, saw blades, reamers, etc.
Sharpening & Updating Outdated Tools:
They precisely restore PCD or PCBN cutting edges original sharpness, profile, and geometry. This greatly increases the service life of ultra-hard cutting tools.
Broad Machine Access:
Worn down tools can be restored with these erosion discs using EDM machines from Walter, Vollmer, Lach, or Enokida.

What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
Why is your product so cost-effective?
A: We cut out the middlemen in the end-to-end manufacturing process and we obtain raw material directly from its source.
Do you do spot quality inspection or full inspection?
A: 100% full inspection for sure. All unqualified products are discarded.
How do you ensure your lead time?
A: From material preparation to machining and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.
What is the MOQ of Copper Tungsten Erosion Discs ?
A: Depends on quantity, generally, no MOQ limit.
How to pay for it?
