Power Feed For Bridgeport Mill is a standard manual knee-type vertical milling machine To be fair, in modern years Bridgeport has also produced CNC machining centers, but it’s the manual vertical knee mills that really made this a household (for people that live in machine shops) name.he Bridgeport knee mill is back and still made in the U.S.A. The Bridgeport knee mill is still made in the U.S.A. by Hardinge Inc. Bridgeportarea-team members stand with the first machine to roll off the line at Hardinge. Hardinge eliminated three machines by slotting its own lathes (B) into the process. Shars APX150 power feed uses a full wave Compound DC Motor which takes advantage of both Shunt-wound DC motor (high initial starting torque) and Series-wound DC motor (constant ratio between speed and torque) technology to generate stable feed rates resulting in minimized cutting vibrations, a smoother finish on the work piece, an even, low speed, and longer cutting tool life. The other import brand power feeds use Series-wound DC motors for their simple design structure and low cost.
