The Role of Copper Wheel Electrodes in PCD Tool Processing

2025-03-05 16:13:16

In PCD (Polycrystalline Diamond) tool processing, copper wheel electrodes play a crucial role in Electrical Discharge Machining (EDM), mainly used for shaping, slotting, and edge finishing of PCD tools. Moresuperhard provides high-precision copper wheel electrodes, which can meet various processing needs for PCD tools and are compatible with customers' existing EDM equipment.

Applications of Tungsten Copper Wheel Electrodes in PCD Tool Processing

1. High-Precision Shaping of PCD Tools

Due to the extreme hardness of PCD, traditional mechanical machining struggles to efficiently remove material. EDM processing with a rotating copper wheel electrode enables high-precision contour shaping while avoiding mechanical stress that could cause chipping. Suitable for machining PCD milling cutters, PCD turning tools, PCD boring tools, and other complex tool geometries.

2. Slotting of PCD Tools

Chip grooves are critical for the cutting performance of PCD tools. Using a copper wheel electrode for EDM slotting ensures precise groove width and depth, enhancing tool stability and cutting efficiency.

3. Edge Finishing and Sharpening

Using Micro-EDM processing combined with a high-precision copper wheel electrode, micro-defects on the tool edges can be removed, improving the overall quality. This process results in a smooth, crack-free cutting edge, increasing sharpness and extending tool life.

How to Optimize EDM Processing with Copper Wheel Electrodes?

To achieve optimal performance when using copper wheel electrodes in EDM processing, manufacturers should consider the following best practices:

1️⃣ Select the Right Electrode Specifications – The size, shape, and material composition of the copper wheel electrode should match the specific tool geometry and machining requirements.

2️⃣ Control Discharge Parameters – Adjusting discharge voltage, pulse duration, and flushing conditions ensures stable and efficient material removal.

3️⃣ Regular Electrode Maintenance – Copper wheel electrodes experience wear over time. Routine reshaping and cleaning help maintain accuracy and performance.

4️⃣ Combine with Diamond Grinding Wheels – After EDM processing, diamond grinding wheels can be used to further refine the tool surface and enhance cutting edge quality.
