Knee Mills & Vertical Machining Centers
Used Bridgeport: Auction & Liquidation
The Bridgeport Series I knee mill is the most widely produced milling machine in American manufacturing history and is still the default toolroom mill in thousands of shops. The brand later passed to Hardinge, which carried it through the EZ-Trak CNC knee mills and the Torq-Cut and GX vertical machining centers. Used demand stays unusually deep for a design this old, because nearly every working machinist has run one and parts, tooling, and retrofit controls remain easy to source.
Popular Bridgeport Models We Sell
Buying Bridgeport
Toolrooms, plant maintenance departments, prototype and R&D shops, job shops that want a manual mill alongside CNC capacity, trade schools and community colleges, and short-run fabricators. Manual Series I mills draw the largest and most local bidder pool at any machine shop auction because they move without a rigging crew; EZ-Trak, Torq-Cut, and GX buyers are shops looking for CNC capability in a small footprint.

A Bridgeport is one of the most reliably sold lots at a machine shop auction: there is always a bidder. What separates a strong result from an average one is condition rather than year, specifically table and way wear, leadscrew backlash, spindle noise, and whether the power feed, DRO, vise, and original tooling stay with the machine.
