American Precision Museum

Experience the historic evolution of the Precision Valley at the American Precision Museum, through the people and inventions in machinery that changed (and continue to change) history.  

The American Precision Museum is located inside the Robbins & Lawrence Armory, a National Historic Landmark built in 1846.  Current exhibits on display spans from "Made By Hand" in the 1820s all the way to 21st Century technology in the Innovation Station, which features a Haas DT-1 Machining Center with Midaco pallet changer and D-Tect It machine monitoring system, industrial robots, and 3D printers.

Learn how machine tools shaped America and see the first Bridgeport milling machine, the Brown & Sharpe SuperMicrometer from 1878, an Ames Blanchard lathe, and more in this International Mechanical Engineering Heritage Collection.

Enjoy our scenic waterfall and garden, and wrap up your visit with a stop in the gift shop with some antique books, STEM toys, and Vermont souvenirs!
