Bridgeport (machine tool brand)

A full view of a Bridgeport Series 1 Knee Mill. The head is mounted on the ram by joints that allow it to swivel in two directions. The ram can slide back and forth on the turret, which can swivel on the column. The table sits on the knee, and it can move horizontally in the X and Y axes. The knee rides up and down the column (one form of Z-axis movement), and the head contains a quill in which the spindle can slide up and down (another form of Z-axis movement or, when the head is swiveled, an additional axis).

The patented "2J" head ensures that any heat buildup in the spindle bearings, belt, or quill area is kept to an absolute minimum. This results in increased belt and bearing life as well as consistent accuracy with no external cooling fans required, increasing rigidity and vibration dampening properties.

Bridgeport stands as a legendary name in the realm of vertical milling machines and machining centers, boasting a long standing legacy that dates back to 1938 under the name of Bridgeport Machines Inc.. Originally sold in 1938 to Textron Inc., this iconic brand embarked on a new chapter when it joined forces with Hardinge, Inc. in 2004. The legacy continued as Bridgeport captured headlines again in 2023, with its latest acquisition by the manufacturing conglomerate InCompass™, marking yet another milestone in its storied journey of engineering excellence and innovation.
