What Is EDM Machining?
In San Antonio, TX, EDM machining removes metal using thousands of tiny sparks—no physical contact required. It all happens inside a bath of dielectric fluid.
Think of it like carving metal with lightning. EDM is ideal for hard or exotic metals, tight internal features, and complex shapes that conventional machining can’t easily reach. It also produces clean, burr-free finishes that often require no secondary processing.
For San Antonio, TX, manufacturers that need complex, high-accuracy components, Roberson Machine Company delivers dependable EDM machining solutions.
Key Advantages of EDM Machining
EDM stands out for its ability to handle complex, high-precision work with ease.
- No Mechanical Stress: Because EDM doesn’t rely on physical contact, it’s ideal for delicate shapes and sensitive internal structures.
- Range of Materials: Hardened steel, titanium, carbide—EDM cuts materials traditional tools can’t touch.
- Zero Tooling Costs: No special fixtures needed, which makes EDM great for fast-turn projects and low-volume jobs.
- Finish-Ready: With EDM, your parts are often ready to ship or assemble without extra touchups.
These benefits combine to minimize secondary steps and cut down on material waste, helping jobs move faster with less overhead.
Industries That Use EDM Machining
From aerospace to medical devices, industries turn to EDM machining when materials are too tough or geometries too tight for conventional methods.
From aerospace to energy, San Antonio, TX, EDM machining plays a role across industries like:
