Hardinge offers the GX 250 5F and GXR 320 5F Bridgeport five-face (4+1) vertical machining centers designed for increased capacity and performance. The machines provide four simultaneous axes plus a fifth axis used only for positioning, enabling a part to be machined on five faces in one single setup. The machining centers are well-suited for use in the job shop or by OEMs, and in the aerospace, medical, electronic, defense, automotive and power-generation industries, among others.
 
The GX 250 5F features XYZ travels measuring 11.8" × 15.6" × 16.9" with rapid traverse rates of 1,181 ipm. A 20-hp, direct-drive spindle motor provides 70.4 foot-pounds of torque. The machining center also is equipped with a 30-tool swing-arm automatic toolchanger.
 
The larger GXR 320 5F features XYZ travels measuring 20" × 24" × 20" with rapid traverse rates of 1,693 ipm on the X and Y axes and 1,415 ipm on the Z axis. The machine features a 25-hp, 12,000-rpm direct-drive spindle with 86.3 foot-pounds of torque, and a 48-tool swing-arm automatic toolchanger.
 
Both machines are equipped with an integrated five-axis rotary table supported by large bearings. Heavy-duty linear guideways and oversized double-nut ballscrews are pretensioned for improved accuracy. The linear way modules consist of slide members or guide trucks and linear rails for a large load rating. Wide spacing between all axes rails increases stiffness. The machining centers also are equipped with a FANUC 0i-D control for 4+1 positioning.
