The American Precision Museum is located in the renovated 1846 Robbins & Lawrence factory on South Main Street in Windsor, Vermont. The museum has the largest collection of historically significant machine tools in the United States.

The building is said to be the first U.S. factory at which precision interchangeable parts were made, giving birth to the precision machine tool industry.

A "machine tool" is a machine which makes parts to other machines, such as screws or gun stocks, generally without a skilled craftsman doing the precision work. Instead, a machine operator controls the machine as it does the precision work. Lathes, milling machines, and drill presses are precision machine tools.

The museum is open daily from 10am until 5pm from Memorial Day Weekend through October. Admission is free on Sundays.
