Custom Engineered Solutions
Some manufacturing challenges can’t be solved with a catalogue. The geometry is too complex, the tolerance too tight, the cycle time target too aggressive, or the process too specific for any machine on the market to handle. That’s where EDM Zap starts.
We’ve been designing and building custom EDM equipment since 1971 — long before custom automation was standard practice. From single-purpose sinker machines for aerospace fuel system components, to fully automated multi-head systems for nuclear applications, every build starts with your problem and ends with a validated, production-ready solution.
We don’t just build the machine. We engineer the entire process — electrode design, fixturing, flush strategy, power supply configuration, and cycle sequence — so that when the machine arrives on your floor, it runs.
What We Build
Dedicated sinker EDM built for one specific part or family of parts — optimized electrode geometry, fixturing, and process parameters for maximum repeatability and minimum cycle time.
Custom EDM integrated with robotic loading, automated fixturing, and downstream process connections — designed for lights-out or minimal-operator production environments.
Bespoke multi-electrode configurations for parts requiring simultaneous machining of multiple features — engineered from the frame up for your specific geometry and throughput target.
Non-standard EDM platforms for unique materials, extreme tolerances, or R&D applications — including nuclear-grade, medical, and experimental process development builds.

"EDM Zap delivered a custom solution that reduced our downtime by 40%. The engineering support was exceptional from day one."
"We've relied on EDM Zap for 20 years. Their calibration team is second to none. When they say precision, they mean it."
What's Included
Heavy fabricated steel frames designed for your specific machine envelope, load requirements, and floor space constraints — built to last decades in production environments.
Custom electrode geometry, material selection, and mounting designed for your specific cavity or feature — optimized for wear rate, surface finish, and cycle time.
Every custom machine ships with a factory-matched EDM Zap Advantage power supply — configured for your specific electrode count, material, and process parameters.
Purpose-built workholding and electrode tooling designed for repeatable, accurate part location — critical for high-volume custom EDM production.
We develop and validate the complete EDM process alongside the machine — power settings, flush strategy, cycle sequence, and electrode management — before the machine leaves our facility.
Our engineers deliver, install, and commission your custom machine on-site. We validate production performance and train your team before we leave.
