How Wire EDM Machining Works
In wire EDM machining (Wire Electrical Discharge Machining), a thin wire is precisely controlled and guided by computer systems as it moves through a workpiece submerged in deionized water. This wire serves as both a guide and electrode, utilizing electrical discharges to accurately cut conductive materials, resulting in parts with finely finished surfaces that typically require minimal further processing. Our state-of-the-art facilities guarantee that even the most complex designs are executed with precision, reflecting our commitment to quality and client satisfaction.
Step 1 Prepare the Workpiece
The first step involves securely clamping the workpiece onto the EDM machine’s worktable to keep it stationary. Next, the surface is thoroughly cleaned and degreased to eliminate any contaminants. It is essential that the workpiece material is conductive, as wire EDM relies on a conductive medium to operate effectively.Step 2 Establish the Electrical Discharge
Next, a thin metal wire is passed through the machine’s guides, and both the wire and workpiece are submerged in a dielectric fluid, typically deionized water. An electrical potential is applied, causing the fluid to break down and generating an electrical discharge (spark) that erodes the surface of the workpiece.
Step 3 Control the Wire Movement
The final step involves precisely controlling the wire’s movement with a computer numerical control (CNC) system. The CNC guides the wire along a predetermined path, allowing it to cut complex shapes and profiles in the workpiece. The dielectric fluid is continuously circulated to remove debris and regulate temperature during the cutting process. Once the cutting is complete, the workpiece is removed, resulting in a high-quality, precisely machined part.

FAQs
What are types of EDM machining?
There are three main types of EDM process.
Wire EDM: This technique uses a thin wire as an electrode to cut intricate shapes and contours in conductive materials with high precision. It’s perfect for creating complex parts with tight tolerances and is commonly utilized in industries like aerospace, medical, and electronics.
Sinker EDM (Ram EDM): This technique employs a custom-shaped electrode that is inserted into the workpiece to create detailed cavities and shapes. It is extensively used in mold-making, die production, and the manufacturing of components with intricate geometries.
Hole-Drilling EDM: This method specializes in drilling small, precise holes in hard materials. It is especially beneficial for creating cooling holes in turbine blades and serves as a preliminary process for wire EDM.
