This Bridgeport Series I CNC Milling Machine, manufactured by Bridgeport Machines (a division of Textron Inc.), is a classic vertical milling unit equipped with Bridgeport's proprietary CNC control system. It operates on 230 volts, three-phase power at 60 Hz, drawing a full load current of 12 amps, with a maximum spindle motor load of 5.6 amps. The machine features a variable-speed head with spindle speeds ranging approximately from 60 to 4200 RPM, adjustable via a manual dial selector. It includes a sturdy 9" x 42" table offering both manual and CNC-controlled movement along the X, Y, and Z axes, with handwheels remaining functional for fine manual adjustments.
