Overview
The DMG Mori NH 6300 DCG is a production-class horizontal machining center in the NH DCG series, offering a 630 mm pallet to handle larger and heavier workpieces than the NH 4000 or NH 5000. Like all machines in the series, it employs DCG (Driven at the Center of Gravity) axis technology to minimize vibration during high-acceleration moves, producing exceptional surface quality at high feed rates.
With a 630 mm square pallet and a maximum pallet load of 800 kg, the NH 6300 DCG addresses the machining needs of larger industrial components — pump housings, gearboxes, hydraulic manifolds, and medium-size structural aerospace parts — that require the productivity and chip evacuation advantages of horizontal machining but exceed the capacity of 500 mm class machines.
The 12,000 rpm spindle is paired with a 37 kW motor providing 350 Nm of torque, enabling aggressive cutting in cast iron, steel, and titanium alloys. Rapid traverse at 60 m/min across all linear axes keeps non-cutting time to a minimum. The standard dual automatic pallet changer enables continuous production cycles, and the 60-tool magazine supports complex, multi-operation workpieces without manual intervention.
The NH 6300 DCG is engineered for integration into flexible manufacturing systems and is routinely deployed in automotive powertrain, heavy equipment, and aerospace manufacturing environments where consistent unmanned operation over extended shifts is the primary performance criterion.

Strengths & Limitations
Strengths
- 630 mm pallet and 800 kg load capacity handle larger industrial and aerospace workpieces
- HSK-A100 spindle taper provides high torque for aggressive cutting in steel and titanium
- DCG drive technology delivers high acceleration without vibration for excellent surface finish
- 60-tool magazine supports multi-operation complex workpieces in unattended production
Limitations
- Higher acquisition cost than 500 mm class horizontal machining centers
- 30,000 kg machine weight requires substantial foundation preparation and installation planning
- 12,000 rpm spindle speed is moderate — high-speed aluminum cutting requires optional higher-speed spindle

Frequently Asked Questions
01
The NH 6300 DCG uses a 630 × 630 mm pallet with an 800 kg maximum load capacity, enabling it to handle workpieces up to 1,000 mm in diameter and 1,250 mm tall — significantly larger than the 400 and 500 mm class machines in the NH series.
02
The NH 6300 DCG offers a larger pallet (630 vs 400 mm), higher load capacity (800 vs 300 kg), greater torque (350 vs 150 Nm via HSK-A100 vs HSK-A63), and a larger tool magazine (60 vs 40 tools). It is intended for larger workpieces in heavy-industry and aerospace applications rather than the smaller precision parts typical of the NH 4000 DCG.
03
Yes. The dual APC with 12-second pallet change time, combined with a 60-tool magazine and integration capability with multi-pallet pool systems and robotic workpiece handling, makes the NH 6300 DCG well-suited for lights-out production environments with extended unattended runs.
