How Precision EDM Machining Can Save You Time and Money

This Simple Machining Process Can Improve Your Bottom Line

Looking to create precise, efficient, and cost-effective tooling? Precision EDM machining could be the right process for you. This advanced machining process has revolutionized the way complex components are produced, offering unparalleled accuracy, intricate detailing, and substantial time and cost savings. But, what is EDM machining and how does it work? Let’s dive in.

How Precision EDM Machining Works

Precision electrical discharge machining (EDM) is also commonly referred to as spark erosion, spark machining, or die sinking. This manufacturing process involves the removal of material from a workpiece using electrical discharges. It’s most commonly used for materials that are difficult to machine because of their hardness, brittleness, or the tooling’s intricate geometries.

So, how does this process work? Controlled electrical sparks are created between an electrode and a workpiece that’s submerged in dielectric fluid. These electrical discharges generate intense heat, which melts and vaporizes small portions of the workpiece material. The melted material is then flushed away by the dielectric fluid, leaving behind a precisely machined cavity or feature.

How This Manufacturing Process Saves Time and Money

As mentioned above, precision EDM machining is commonly used on materials that are hard, brittle, or have complex shapes. These materials are too difficult to machine using traditional methods; your costs would dramatically increase if you tried to use these machining methods. But, there are other ways precision EDM machining can save you money:

Reduced Tool Wear and Longer Tool Life

EDM doesn’t involve direct mechanical contact between the tool and the workpiece, which leads to minimal tool wear. Since there are no cutting forces involved, tools experience less stress and wear during the machining process.

Elimination of Secondary Processes

EDM produces high-quality surface finishes without the need for additional finishing operations like grinding and polishing. This saves labor time, which dramatically reduces costs.

Create Complex Geometries in One Operation

Because EDM can create complex geometries, it eliminates the need for multiple setups or tool changes.

Minimal Material Loss

This machining process has a low material removal rate compared to some other methods. Therefore, it can minimize costs by diminishing waste.

Reduce Heat Affected Zone

EDM creates localized heat, resulting in a small heat affected zone around the machining area. It decreases the risk of material distortion or degradation.
