What Is Wire EDM?

Wire EDM (Wire Electrical Discharge Machining) is a process within EDM manufacturing that works by continuously feeding a wire electrode under tension in a vertical axis. A discharge voltage is applied through the wire electrode, through a dielectric fluid, and into a grounded workpiece. The workpiece moves in an XY plane to trace a cut pattern through the material. This erosion can begin at the outer edge of the workpiece or a hole can be drilled first as the starting point for a closed cut path.

Wire EDM uses a thin electrode wire controlled by a CNC EDM system to cut or shape a metal workpiece. The wire is electrically charged, and sparks form between the wire and the workpiece, melting the workpiece surface. Since the cutting wire never directly contacts the workpiece, there is no distortion of the cut path or shape of the material.

At our facility, we offer state-of-the-art wire EDM CNC services utilizing advanced slow wire EDM machines. Our equipment provides exceptional precision, with an accuracy of up to 0.002 mm. This high level of precision ensures that we can handle even the most demanding requirements for intricate and complex parts.

Capabilities and Features

Precision and Accuracy

• Tolerance: Our slow wire EDM machines achieve a precision of 0.002 mm, making them suitable for extremely detailed and high-accuracy applications.

• Maximum Cutting Angle: Our machines can cut at angles up to 30°, enabling us to create parts with complex geometries and varying cross-sections.

Specialized Cutting Techniques

• Upper and Lower Irregular Shapes: We can produce components with different shapes on the top and bottom surfaces, thanks to our capability to cut at multiple angles.

• Copper Wire: We use 0.2 mm copper wire for our slow wire EDM, ensuring optimal cutting quality and wire longevity for single-use applications.

• Molybdenum Wire: For medium-speed EDM, we utilize 0.18 mm molybdenum wire, with the finest wire being 0.15 mm. This wire has a lifespan of 4-5 days, making it a cost-effective option for various projects.

In addition to wire EDM, we also support Sinker EDM machining, also known as RAM EDM or Plunge EDM, for applications requiring deep cavity formation or highly detailed 3D features that are not achievable with wire EDM alone.

Advantages of Our Wire EDM Services
