Charter Oak Automation, locally owned and operated in Connecticut, manufactures high-quality CNC systems produced on our own Turnkey CNC Mills. Our CNC Products are designed and assembled in the USA, with many of our components being machined right here in the United States, and more work being onshored with each iterative redesign.

We’re now accepting orders for our popular CNC Turnkey Mill — the newest engineering revision includes completely redesigned electrical and electronics systems, but retains the immense power and enormous working envelope that our customers demand. Our CNC mill is affordable, fast, powerful, extremely accurate, and reliable for production runs, 3D prototyping, R&D work, and anything else you can fit on it.

Check out our products and see if we can put together a package to suit your needs.

Turnkey CNC Mill

Charter Oak Automation’s 3-axis or 4-axis CNC mill has the largest working envelope in its class, at a whopping 26" × 12½" × 22" (XYZ) (almost three times the size of our biggest competitor) with enormous 26" × 12½" × 22" (XYZ) travels, and has double their horsepower.

Square Column Bed Mills

The 12Z manual mill provides an enormous  26" × 12" × 22" (XYZ) working envelope and 39½" × 9⅜" bed for large projects, and comes with a large 12″ diameter head mount for increased rigidity. For smaller jobs or space-limited home workshops, our RF-45-style benchtop mill provides a similar design in a smaller, inexpensive package. A full range of options and upgrades for both machines lets your mill grow over time to match your needs.
