When to Use a CNC Mill vs. a Bridgeport Mill
The Bridgeport Series I Standard Knee Mill is the original milling, drilling, and boring machine. The Bridgeport Series I is the most popular mill ever made, with over 370,000 machines built over the past 80-plus years, followed by the larger Bridgeport Series II. Today, Bridgeport milling machines are manufactured by Hardinge.
