Micro Milling



Machining the Impossible – Micro Milling Services

Micro Milling not only supports our electrical discharge machining processes like Wire EDM and Sinker EDM, it is also offered as a stand-alone service to our customers in a wide range of industries. Our 3-Axis CNC mills are capable of cutting with tools smaller than the diameter of a human hair. Advanced thermal controls integrated directly into the structure of our 3-Axis milling machinery ensure consistent cutting performance and production of quality components. Scalable machine tending robotic automation tied to each 3-Axis CNC mill allows for continuous production to run around the clock.


What is Micro-Milling?

While very similar in motion to larger 3-Axis CNC milling machines where the cutting tool moves across the X, Y, and Z linear axes, micro-milling machines construction differs by using an extremely stiff frame design, enhanced guideways systems, advanced thermal controls, ultra-responsive servo motors, extremely high speed motorized spindles and world-class industrial CNC controls. These specific differences set micro-milling machines into a complete class of their own which allows them to achieve micron level accuracy, repeatability and surface finishes that no standard CNC milling machine can match. Micromilling machines can produce features smaller so small that high power magnification is required to even see them.

Micro-Milling Capabilities

Tighter Tolerances equal better finishes when it comes to milling. The 3-Axis CNC Micro Milling equipment used at EDM Intelligent Solutions offers precision micro milling capabilities with tight tolerances as tight as 0.0002″ (2-3µm micron). Constant development of new and improved machining techniques allows us to continuously offer our customers tighter tolerances and better finishes that set us apart from other precision CNC machine shops. Working with our vast network of suppliers, we have access to any tool needed to meet your milling, micro milling or micro manufacturing needs. In some cases, the tooling used is so small in diameter (as small as 0.0010″) that the cutting end is barely even visible to the naked eye. Continuous access to and timely delivery of standard and custom micro-milling tools made to our exacting requirements from a variety of standard and exotic materials is also made possible by this network of suppliers. This ensures that our CNC milling machines are never left waiting cutting tools to arrive while the milling process is active 24/7. Extreme machining efficiencies are possible due to the integrated automation that changes both cutting tools and workpieces with no human intervention. This enhances overall productivity and saves our customers’ time and money. Our decades of CNC machining experience and state-of-the-art equipment enable us to provide repeatable quality parts and components from nearly any type of material.

We are continuously working with our technology partners to upgrade our CNC milling capabilities to meet the ever-evolving needs of our diverse base of customers. We also complement our micro milling capabilities with other manufacturing services like Wire EDM and Sinker EDM , as well as 3D measurement of machined components for full quality assurance.
