Bridgeport Machines of Bridgeport Connecticut so dominated the milling machine market for such a long time that their machine "The Bridgeport" is virtually synonymous with "Manual milling machine." Bridgeport vertical milling machines have been so successful and ubiquitous that, within the machining industries, the Bridgeport is an archetypical example of that class of machine, and the name Bridgeport often functions colloquially as a genericized trademark.

The bulk of the machines that Bridgeport made from about 1965 onward used an R8 collet system. Prior to that, most of the machines used a Morse Taper #2 collet system.Bridgeport is now owned by Hardinge Brothers (NASDAQ : HDNG) of Elmira, New York .
