One brand of milling machine deserves special mention. The Bridgeport Vertical Knee mill, built by the Bridgeport Machine Tool Company and introduced in 1936, has become a hallmark brand name for vertical knee milling machines. Although they did not invent the concept of vertical milling they did introduce a revolving turret and ram system that allowed the milling head to be positioned anywhere over the table. This idea has been copied into every other brand of vertical knee mill today. So popular was the Bridgeport mill that many seasoned machinists still call all vertical knee mills "Bridgeports".
