Machine Comparison
Hardinge Conquest H51 vs INDEX G200
Hardinge vs INDEX-Werke · CNC Lathes
Summary
The Hardinge Conquest H51 and the INDEX G200 are bar-fed turning centers with near-identical turning length, 648 mm (25.5 in) against 660 mm (26 in). The INDEX is the larger and stronger machine: 65 mm (2.6 in) bar against 51 mm (2.0 in), a 20 / 24 kW spindle against 15 kW (20 hp), and 6,000 rpm against 5,000 RPM.
The INDEX G200 also has more travel, 230 mm (9.1 in) in X against 171 mm (6.75 in) and 845 mm (33.3 in) in Z against 581 mm (22.87 in). The H51 swings a larger part, 312 mm (12.3 in) against 200 mm (7.9 in), takes an 8 in chuck against 165 mm (6.5 in), and is lighter at 6,804 kg (15,000 lb) against approx. 8,500 kg.

Advantages
Hardinge Conquest H51
- 312 mm (12.3 in) maximum turning diameter against 200 mm (7.9 in)
- 8 in chuck against 165 mm (6.5 in)
- Choice of Fanuc 0iD, Siemens 840D or Mitsubishi M720V control
- Lighter machine at 6,804 kg (15,000 lb) against 8,500 kg (18,739 lb)
INDEX G200
- 65 mm (2.6 in) bar capacity against 51 mm (2.0 in)
- 20 / 24 kW spindle against 15 kW (20 hp)
- 6,000 rpm spindle against 5,000 RPM
- 845 mm (33.3 in) Z travel and 230 mm (9.1 in) X travel against 581 mm and 171 mm
Verdict
Choose the INDEX G200 for high-volume bar work up to 65 mm (2.6 in), such as automotive shafts, hydraulic pistons and medical implants, where 20 / 24 kW, 6,000 rpm and long Z travel suit complex turned-and-milled parts. Choose the Hardinge Conquest H51 for chuck work up to 312 mm (12.3 in) in diameter and for collet-based precision fasteners and fittings, especially in shops already standardized on Hardinge workholding.
