Hyundai WIA KH6300/8000

The Hyundai WIA KH6300/8000 is a heavy-duty horizontal machining center platform available in two pallet configurations — 630 x 630 mm and 800 x 800 mm — sharing the same massive spindle, gearbox, and structural platform. This dual-size approach allows manufacturers to specify the pallet class that best matches their workpiece requirements while benefiting from the same proven heavy-cutting architecture. Both variants use a gear-driven two-step spindle delivering an enormous 2,193/1,074 Nm of torque through a BT50 taper at 6,000 RPM from 45/22 kW (60/30 hp).

The KH6300 variant with its 630 x 630 mm pallet provides 1,050/850/1,000 mm (41.3/33.5/39.4 in) X/Y/Z travels with workpiece capacity up to 1,200 kg and rapids of 30/30/30 m/min. The KH8000 variant with its 800 x 800 mm pallet extends travels to 1,400/1,050/1,200 mm (55.1/41.3/47.2 in) with workpiece capacity up to 2,000 kg, though rapids reduce to 24/24/24 m/min due to the heavier moving mass. Both feature rotary trunnion-type APC with 12 and 16-second pallet change times respectively.

The 2,193 Nm spindle torque figure is remarkable for the 630/800 mm pallet class — significantly exceeding the torque output of most competitors. This positions the KH6300/8000 platform squarely in the heavy-cutting segment: large cast iron engine blocks, transmission cases, heavy equipment structural castings, and power generation components where material removal rate is the primary productivity metric. The 60-tool ATC serves both variants, and the Fanuc 31i-B Plus control provides full 4-axis capability with high-speed machining functions.

Box guideway construction on all axes provides the rigidity foundation this torque level demands. The KH6300/8000 is not a high-speed machine — it is an unapologetically heavy-cutting platform for shops where spindle torque and cutting rigidity determine profitability. At $450,000-$700,000 depending on variant and configuration, the platform offers compelling value against comparable heavy-cutting HMCs from Toyoda, Okuma, and Mazak.
