Wire EDM Machining

Wire EDM (electrical discharge machining) is an accurate and effective method of producing custom parts and components from metal. Petersen Precision has been using wire EDM technology for nearly three decades, and we have the experience and expertise to deliver high precision parts that perfectly match our customers’ designs.

If you need tight tolerance flat metal parts, our wire EDM services are the ideal solution. Request a quote or contact Petersen Precision to learn more.

25+ Years of Wire EDM Excellence

We started using wire EDM technology in the early 1990s to make the tooling and dies for our other manufacturing processes. Several years later, we expanded our EDM department to include full production capabilities for customer projects.

Today, we utilize a fleet of state-of-the-art Mitsubishi wire EDM machines to produce tooling and dies and custom two-dimensional metal parts and components for our customers. We continuously upgrade our wire EDM technology to ensure that we have the most advanced capabilities available.

Most of our EDM systems (about 2/3) are used for customer part production, with the remainder dedicated to tool and die making. However, we can scale our production capabilities as needed, and transition some or all of our tool and die EDM processes to part production to deliver high-volume part orders as quickly and efficiently as possible. This flexibility is advantageous for us and for our customers.

Tight Tolerance EDM Machining

Wire EDM is an extremely accurate machining process. It uses an electrically-charged, razor-thin wire as the cutting tool, with CNC programming to guide the wire through a designated pattern.

Our wire EDM systems can hold tolerances of better than ±0.0001” in multipass cuts to create 2-D forms. We can produce parts from flat stock up to 5” thick or more, with the same high precision and tight tolerances regardless of material thickness. With full CNC control, even the most complex designs can be reproduced with excellent accuracy and repeatability. We work with your CAD or other digital design files to create parts that match your exact specifications.

“Lights out” wire EDM capabilities allow us to maintain 24/7 production, as needed, for faster turnaround. Careful planning and part nesting results in high yields with minimal scrap for lower material costs.

Wire EDM Materials

With wire EDM, essentially any metal can be processed with equal precision and accuracy. However, most of our wire EDM machining work involves:
