Overview
The Hardinge GX-710 is a mid-range vertical machining center from the GX series, offering X/Y/Z travels of 710 x 510 x 510 mm (28.0 x 20.1 x 20.1 in). This is the same envelope as the Hardinge Bridgeport V710 but in the newer GX platform, incorporating updated spindle technology, improved thermal management, and a more rigid machine structure. The GX-710 targets precision job shops and production facilities that need a versatile 28-inch-class VMC with accuracy above commodity-level machines.
The spindle delivers 11 kW (15 hp) continuous power at speeds up to 10,000 RPM through a BT 40 taper, with an optional 15,000 RPM direct-drive spindle for aluminum-intensive applications. Hardinge's spindle engineering heritage, developed through decades of precision lathe manufacturing, translates to spindle runout and positioning accuracy that surpass typical production VMCs. The machine structure uses a rigid C-frame design with linear guideways on all three axes for smooth interpolation and fast rapid traverse.
The work table measures 800 x 450 mm (31.5 x 17.7 in) with T-slots on standard centers, supporting workpiece loads up to 500 kg (1,102 lb). A 24-tool automatic tool changer provides quick tool changes with tool-to-tool times of approximately 2.2 seconds. Rapid traverse rates of 36 m/min (1,417 ipm) on all axes ensure efficient non-cutting positioning. Through-spindle coolant is available as an option for titanium and hardened steel applications.
Running on Fanuc 0i-MF Plus control, the GX-710 provides full G-code programming, conversational Manual Guide i, and network connectivity. New GX-710 machines price between $75,000 and $125,000 depending on spindle configuration and options. The machine competes with the Haas VF-3, Hurco VMX30i, and DMG Mori CMX 600V in the mid-size VMC segment.

Strengths & Limitations
Strengths
- 710 mm X-travel provides a versatile work envelope for the majority of job shop and production milling applications
- Hardinge's precision spindle engineering delivers accuracy and surface finish above commodity VMC benchmarks
- 24-tool ATC handles most complex multi-tool programs without requiring mid-cycle tool management
- Optional 15,000 RPM direct-drive spindle enables aggressive high-speed aluminum machining
- Linear guideways deliver smooth interpolation and 36 m/min rapid traverse for efficient cycle times
- Fanuc 0i-MF Plus control provides broad CAM post-processor compatibility and operator familiarity
Limitations
- 11 kW spindle power is adequate for general work but limits aggressive roughing in hard materials compared to 15-18.5 kW competitors
- Hardinge's North American service network is smaller than Haas or Mazak, potentially affecting service response times
- BT 40 tooling limits heavy-duty cutting compared to CAT 50 or HSK-A63 machines in the same size class
- The GX-710 occupies a crowded market segment where Haas VF-3 dominates on price and service network size

Frequently Asked Questions
01
The Haas VF-3 offers slightly more X-travel (1,016 mm vs 710 mm) and significantly lower entry pricing. The GX-710 counters with Hardinge's precision spindle engineering and superior accuracy specifications. The Haas has a far larger installed base and dealer network. For shops where accuracy is the primary differentiator, the GX-710 has the edge; for value and support breadth, Haas is the practical choice.
02
The standard spindle is a 10,000 RPM belt-drive unit with 11 kW continuous power. A 15,000 RPM direct-drive spindle option is available for aluminum-intensive work, eliminating belt vibration for improved surface finish. Both use BT 40 tooling. Through-spindle coolant up to 20 bar is available for deep-hole drilling and titanium machining.
03
New GX-710 machines price between $75,000 and $125,000. Base configurations with standard 10,000 RPM spindle and Fanuc control start near $75,000. Adding through-spindle coolant, high-speed spindle, 4th axis prep, probing, and chip conveyor pushes configured prices toward $125,000.
04
Yes. The GX-710 offers 4th axis preparation as a factory option, including control software and wiring. The 800 mm table accommodates standard rotary tables from Haas, Tsudakoma, and Nikken. A 4th axis package typically adds $8,000-$15,000 depending on rotary table brand and size.
