Hyundai WIA KH1000

The Hyundai WIA KH1000 is a large-format horizontal machining center with a 1,000 x 1,000 mm (39.4 x 39.4 in) pallet, built for machining the largest prismatic workpieces encountered in heavy industry, power generation, and large automotive structural components. With 2,100/1,350/1,400 mm (82.7/53.1/55.1 in) X/Y/Z travels, the KH1000 delivers a massive working envelope that accommodates tombstones, large fixture plates, and multi-part setups that exceed the capacity of 630 mm and 800 mm pallet machines.

The gear-driven two-step spindle with BBT50 taper delivers 807/686 Nm of torque at up to 8,000 RPM from 26/22 kW (35/30 hp). The BBT50 taper (big-bore BT50) provides enhanced contact area between tool holder and spindle for improved rigidity and power transmission at the heavy cutting loads the KH1000 is designed to handle. The two-step gearbox ensures strong torque delivery across the entire speed range, critical for the varied cutting conditions encountered when machining large multi-feature workpieces.

The 60-tool ATC provides the tooling capacity complex large-part programs demand. Box guideway construction on all axes delivers the rigidity and vibration damping required for heavy roughing passes at aggressive depths of cut. The two-pallet shuttle APC with 110-second pallet change time keeps the spindle cutting while operators load the second pallet — the longer swap time reflects the engineering challenge of moving 1,000 mm pallets loaded with workpieces up to 3,000 kg.

Rapids of 20/20/20 m/min are appropriate for the box guideway design and the massive moving components involved. At $600,000-$900,000 new, the KH1000 is a significant capital investment, but the 1,000 mm pallet class is inherently expensive. The KH1000 competes with the Mazak HCN-10800, Okuma MA-900H, and Toyoda FH1000S while offering Hyundai WIA's competitive pricing advantage.
