What is wire and sinker EDM?
Wire EDM (Electrical Discharge Machining) and sinker EDM are machining methods used to cut complex shapes in hard metals like hardened steel. In wire EDM, a thin metal wire makes the cuts. Sinker EDM uses a shaped electrode to create the desired cut.
Both methods involve passing an electrical discharge between the metal piece and the cutting tool, which erodes the metal into tiny particles, allowing for precise cuts and detailed shapes that are hard to achieve with traditional machining methods.
Wire EDM is best for cutting thin or delicate parts, while sinker EDM is commonly used to make molds or dies. Both EDM techniques are used in the aerospace, automotive, medical devices, and precision engineering industries.
How does wire EDM work?
Wire EDM, or Electrical Discharge Machining, is a precise method of cutting hard materials. It uses a thin, electrically charged wire to make accurate cuts in metals and other conductive materials. The process involves creating an electrical spark that melts the surface of the workpiece. A special fluid flows around the cutting area to remove the melted material. As the wire moves continuously, it creates sparks, forming the final product’s desired shape.
How does sinker EDM work?
Sinker EDM (Electrical Discharge Machining) is a manufacturing process that uses a shaped electrode, usually made of graphite or copper. This electrode is placed in an electrically conductive fluid together with a workpiece. An electrical charge flows between the two, creating sparks as the electrode is near the workpiece. These sparks melt the surface material of the workpiece, and the fluid washes away the melted material. The electrode continues this process, shaping the workpiece until it is complete.
What is the difference between Wire & Sinker EDM?
Wire EDM and sinker EDM are two types of Electrical Discharge Machining. The main difference is that wire EDM uses a thin wire as the electrode to cut through the workpiece, while sinker EDM uses a shaped electrode to form the desired shape in the workpiece.
Wire EDM is suitable for cutting intricate shapes and parts requiring tight tolerances. Sinker EDM works better for creating deeper cavities and shapes in larger workpieces. Another key difference is that wire EDM keeps a constant gap between the electrode and the workpiece. In contrast, sinker EDM submerges the electrode in a dielectric fluid to cool it and wash away debris.
Both processes have their advantages and limitations. Choosing between them depends on the requirements of the job.

Wire & Sinker EDM Finishes
Electrical Discharge Machining (EDM) is a versatile manufacturing process that produces high-precision components. The standard finishing and post-processing techniques for EDM parts include:
Deburring: This involves removing any sharp edges or burrs left from the EDM process.
Polishing: This technique improves the surface finish and reduces roughness through mechanical polishing.
Plating: A thin protective metal coating enhances corrosion resistance or improves appearance.
Heat Treatment: This process enhances the component’s hardness, strength, or other properties.
Passivation: This involves forming a protective oxide layer to prevent corrosion.
These techniques help ensure that EDM parts meet the required specifications and performance standards.
Electric Discharge Machining vs Conventional Machining
Electric Discharge Machining and conventional machining are two different manufacturing methods, each with its benefits and uses. EDM uses electrical discharges to wear away material, making it great for detailed and complex shapes. In contrast, conventional machining uses mechanical tools to cut away material, giving it more flexibility for different part sizes and materials.
When choosing a manufacturing method, consider important factors like the complexity of the part, the material, and your production needs. These decisions will help you find the best solution for your project.
