Founded in 1899 in Boston, MA, the company moved to Cambridge in 1904 after a fire. The company was relocated to Windsor Vermont in 1972 and was called Cone-Blanchard Machine Company at that time and made Cone automatic screw machines and Springfield vertical grinders. They left Windsor in 2002.

For a century, Blanchard grinders have been used to flatten surfaces, much faster than traditional surface grinders but to slightly looser tolerances. A video tour of the Bourdelais Grinding Shop shows several Blanchard grinders, including one 60-inch machine from the 1920s that is still in use.

Blanchard grinders are still being made Bourn & Koch Inc.

Around 1911, Blanchard made a short-lived foray into manufacturing gas engines.
