Hardinge has announced the release of two all-new Bridgeport 5-Face (4+1) vertical machining centres – the GX 250 5F and GXR 320 5F.

These new machine tools are designed for use in the OEM, aerospace, medical, electronic, defense, automotive and power generation industries, among others.

Two machine sizes are available and come standard with a Fanuc 0i-D control for 4+1 machining.  The term 4+1 refers to the use of four simultaneous axes plus one axis that is used for positioning only.

4+1 machining allows the part to be machined on 5 faces in one single set up. The part remains in one fixture instead of being moved from one fixture or vise to another, reducing set-up time while improving accuracy.

The GX 250 5F (4+1) with travels of 11.8” x 15.6” x 16.9” (X,Y,Z) provides fast rapid traverse of 1181 inches per minute on X, Y and Z axes and features a powerful 20hp, 15,000-rpm direct-drive spindle motor with 70.4 ft-lbs of torque and a 30-tool swing-arm automatic tool changer.

The larger GXR 320 5F (4+1) with travels of 20” x 24” x 20” (X,Y,Z) provides very fast rapid traverse of 1693 inches per minute on X and Y axes and 1417 inches per minute on the Z axis.

The machine also has a powerful 25hp, 12,000-rpm direct-drive spindle with 86.3 ft-lbs of torque and a 48-tool swing-arm automatic tool changer.

The machining centres are designed with an optimum work envelope to machine small to medium parts.

Both machines also come with features like a BIG-PLUS spindle, oil chiller, chip conveyor, coolant flush system, preparation for through spindle coolant (with rotary unio), coolant wash down gun, tri-color stack light and other standard control features.
