At Erodex, we specialise in high-precision EDM machining products and support, helping UK manufacturers achieve micron-level accuracy across a range of industrial applications. Whether you’re producing cooling holes in turbine blades or machining surgical tools, our solutions ensure exceptional EDM precision with consistent, repeatable results.
We serve clients in aerospace, automotive, medical, energy, and toolmaking, supplying precision-engineered electrodes, tubing, fixturing and expert advice to support EDM spark erosion processes.
What is EDM Precision?
EDM precision refers to the ability to machine complex, intricate, or extremely small features with incredible accuracy using Electrical Discharge Machining (EDM). Unlike traditional cutting tools, EDM uses controlled electrical sparks to erode material from a conductive workpiece. This makes it ideal for components requiring:
- Ultra-fine tolerances
- Delicate features and internal corners
- High surface quality
- Zero mechanical stress
At Erodex, our range of EDM materials and consumables are engineered specifically to support high-accuracy machining across both Fast Hole Drilling and Die Sinking EDM applications.
Key Benefits of High-Precision EDM Machining
- Sub-micron accuracy – Achieve incredibly tight tolerances
- No tool pressure – Perfect for delicate or thin-walled components
- Excellent surface finishes – Reduces or eliminates polishing stages
- Consistent performance – Ideal for repeated production runs
- Works with hard materials – Including tool steels, carbides, and superalloys
