Charter Oak Automation’s CNC Products are designed and assembled in the USA. Many of our components are machined right here in the United States, with more work being onshored with each iterative redesign.

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.
