Micro Manufacturing


What is Micro Manufacturing?

Manufacturing at a micro scale requires machining processes capable of micron level tolerances and repeatability. Many micromachined components incorporate features that are only a few microns in size and require absolute accuracy. Sometimes referred to as micro/meso-scale mechanical manufacturing (or M4 processes), micromachining typically creates products using specialized machinery that is purpose built to establish superior accuracy and consistency between the miniature parts being produced. Ongoing product miniaturization in a multitude of industries is requiring ever smaller and tighter tolerance components to be produced.

EDM Intelligent Solutions has been at the forefront of unique micromanufacturing techniques applied to traditional electrical discharge machining processes for 25 years. Coupled with extremely high resolution automated 3D metrology systems, the micro manufacturing team at EDMIS is able to machine some of the tiniest, most intricate and extremely delicate parts that can be designed.

If your part is too small for the other CNC machine shops that offer micromanufacturing, odds are that it is perfect for the EDM Department at EDMIS.


As industries continue to miniaturize their products due to demand for ever smaller and more efficient technologies, the need for tighter tolerance machining and manufacturing processed continues to grow. It is not uncommon to see various components be manufactured at EDM Intelligent Solutions that are not visible to the naked eye. The extremely high magnification automated 3D measurement and inspection systems produced by our 3D Metrology Systems group are directly integrated into the micro manufacturing operations and processes used by the EDM Department at EDMIS to machine impossibly small and delicate parts while meeting tolerances as tight as 1 micron.

When components require extremely small and deep holes and/or micro sized through holes, Fine Hole EDM Drilling should be considered. Fine Hole EDM services are well suited for parts requiring intricate tolerances, the limitation of material stress and thermal heating, and those needing superior surface roughness finishes. Small Hole Sinker EDM drilling is sometimes the only machining method that can produce such tiny holes when materials that are too hard or too brittle are required by design. Conventional machining methods like CNC drilling may not even have drills small enough available to match the sizes that Fine Hole EDM Drilling can produce. Through integrated machine automation, the quantities of parts being completed can easily be scaled up to meet the high volumes required by some of our largest customers.

This is just a small sample of all the types of components that EDM Intelligent Solutions has manufactured using our advanced Wire EDM machining processes. There really aren’t many types of parts that EDMIS has not worked on in some form over the last 25 years serving these industries. No project is too big or part too complex or tolerance too tight for EDM Intelligent Solutions which makes us the preferred partner for OEM manufacturers nationwide.

Who is SLAC?

The SLAC National Accelerator Laboratory is one of ten Department of Energy (DOE) offices of science laboratories and is operated by Stanford University. They’ve built the world’s longest particle accelerator, discovered some of the fundamental building blocks of matter and created the first website in North America. EDM Intelligent Solutions is a preferred manufacturing partner to many of the engineering and research teams at SLAC.

What did EDMIS do with SLAC?

Our company was able to utilize micro manufacturing capabilities to produce the necessary components for SLAC particle accelerator testing experiments. Specifically, copper and stainless steel structures were micro-machined to study the effect of “material on rf breakdown at short pulse, 100 GHz”-SLAC. EDM Intelligent Solutions is capable of aspect ratios up to 38:1, feature sizes as small as 40μm and tolerances as low as 1 micron which, in this instance, allowed for extremely precise experiments and testing.
