The mill is made almost entirely of cast iron, weighs about 1500kg and provides a 457x305x127mm (X/Y/Z) working area, adjustable along the Z axis within further 365mm by moving the knee. Major cast parts are shared with the Bridgeport Series 1 CNC mill, which is equipped with a much more advanced control, but lacks handwheels for manual operation. Other mills sharing all or most major parts include Bridgeport BOSS, Bridgeport EZ Trak and early Bridgeport Interact models. | The mill is made almost entirely of cast iron, weighs about 1500kg and provides a 457x305x127mm (X/Y/Z) working area, adjustable along the Z axis within further 365mm by moving the knee.

The X (table), Y (saddle) and Z (quill) axes are driven by SEM MT30H4-44 permanent magnet brushed DC servo motors equipped with built-in tachometers and fitted with coaxial Heidenhain ROD 450B 125line/rev sin/cos encoders. The servos drive 5mm/rev ball screws through toothed belts at a 2:1 reduction ratio. Notably, the X and Z ball screws are stationary and the nut, integrated with a belt pulley, is being rotated around them.
