Custom Engineered Solutions
A failed EDM doesn't just stop production — it stops your entire downstream process. Our repair and maintenance service gets your machine back online fast, with the expertise to fix it right the first time.
EDM Zap has been repairing and maintaining sinker EDM equipment since 1971 — including classic Elox, ERM, Xermac, and many other brands. Our technicians travel on-site across North America, often same-day or next-day, or you can ship equipment directly to our facility in Montgomery, IL.
We also offer preventive maintenance programs to keep your machines running at peak performance year-round — reducing unplanned downtime before it hits your production schedule.
