When a feature is too fine, too hard, or too delicate for conventional machining, OEMs partner with Nanotech Precision. Our micro EDM process produces burr-free, micron-accuracy features at production scale.
Micro EDM (Electrical Discharge Machining) is a non-contact machining method that uses controlled electrical sparks to erode material with sub-micron precision. It’s ideal for creating ultra-fine details — micro holes, slots, and chamfers — in delicate or hard-to-machine materials, without generating heat, burrs, or mechanical stress.
At Nanotech Precision, micro EDM is a core competency. Backed by decades of precision tooling experience from our sister company, Die Technology, we specialize in fine wire EDM, micro EDM milling, and micro drilling EDM using wire diameters as small as 30 µm (0.0012”). With tens of thousands of production hours logged annually, we deliver precise, repeatable results for complex micro components in medical, aerospace, and electronics applications.
Our process expertise, paired with high-end equipment and proprietary workholding, makes us a go-to partner for small wire EDM projects that demand absolute accuracy — including swiss wire EDM work that adds fine features to Swiss-turned components.
Micro EDM is a subtractive process that removes material through a series of electrical discharges (sparks) between an electrode — typically a thin wire — and the workpiece. Each spark melts and vaporizes a microscopic amount of material, enabling extreme precision even in hard, conductive materials like titanium, Inconel, and tungsten.
Unlike traditional cutting or milling, EDM introduces no mechanical force, making it ideal for fragile geometries, thin walls, and small cross-sections. It’s the process of choice when conventional machining reaches its limits — think micro holes down to 0.0015”, ultra-thin slots, or sharply defined corners on parts smaller than a paperclip.
In regulated industries especially, micro EDM is critical to producing high-precision features that must be burr-free, accurate, and repeatable. From micro catheter tooling to aerospace sensors and surgical instruments, EDM enables miniaturization and reliability in ways few other processes can.
With tens of thousands of hours logged annually in micro EDM and a legacy of precision tooling excellence, Nanotech Precision brings unparalleled capability to every EDM project. Our ultra-precise equipment, expert team, and custom workholding let us produce the most delicate micro features at scale.
But we don’t try to win every project. We build responsible relationships with people who value what we bring to the table, and then we deliver, order after order. Clients choose us when tolerances are tight, features are complex, and failure is not an option.
Nanotech Precision partners with OEMs in regulated industries that share alignment in values and purchase components with micro features at high volumes. The Innovation Lab partners with R&D groups in regulated industries developing next generation products. We target ideal-fit partners who share our values and have the potential to become strategic, long-term customers.
We work with wire diameters as small as 30 µm (0.0012”) and produce micro features just as small, holding tolerances as tight as 0.000050”. Send your drawing and we’ll confirm what’s achievable for your part.
Any conductive material, including hard and exotic alloys like titanium, Inconel, and tungsten that are difficult or impossible to machine conventionally. Our EDM systems also produce oxidation-free finishes, which matters for rust-prone, medical-grade components.
EDM removes material with electrical sparks rather than mechanical cutting, so there’s no contact force, no burrs, and no machining stress. That makes it ideal for fragile geometries, thin walls, and small cross-sections that traditional milling or turning would distort.
Yes, that’s a core part of our workflow. We frequently use micro EDM to add fine features to Swiss-turned components, combining processes in-house to deliver a finished micro component.
Absolutely. We log thousands of hours per year per machine and produce millions of micro features annually, using proprietary workholding and lights-out machining for repeatable, high-volume output.
Nanotech Precision is ISO 13485:2016 certified (Cert. #5747MED001) and CMMC 2.0 Level 2 certified.
