Small Hole Wire EDM – Frequently Asked Questions
How does the small hole EDM process work?
Small hole EDM machines contain a special electrode that spins around a spindle like a drill bit on a drill.
The special electrode enables the machine’s electric cutting spark to drill deep, angled holes in metal plates, hardened alloys, and other electrically-conductive materials.
How does small hole EDM drilling remove broken taps?
An electrode is drilled through the center shaft, allowing the remaining pieces to be removed without damaging the existing threads.
What angles can you drill?
The driller head can tilt 45 degrees. We can also utilize various fixture setups to accommodate compound angles, even on round surfaces.
Can you drill on angled or round surfaces?
Yes! CNC drills tend to walk on an angled surface due to torque pressure, but the EDM electrode doesn’t come into contact with the part, so holes remain accurate.
What equipment do you use?
We use a Current CT300 EDM Drilling Machine, and we accept various drawing formats in order to generate quotes (dxf, igs, dwg, dwf, xt, sldprt, pdf)
