Hyundai WIA KH63G

The Hyundai WIA KH63G is a mid-size horizontal machining center designed for high-volume prismatic part machining in automotive, hydraulics, and general manufacturing. The 630 mm pallet size places the KH63G in the most common HMC pallet class, allowing it to handle the medium-to-large prismatic workpieces that define high-production horizontal machining. With a 630 x 630 mm pallet, 900 x 900 x 900 mm (35.4 x 35.4 x 35.4 in) X/Y/Z travels, and 8,000 RPM spindle, the KH63G is built for aggressive chip-making in production environments.

The 37/26 kW (50/35 hp) spindle is a significant power plant for the 630 pallet class, and the CAT 50 / BT 50 taper handles the heavy tooling loads common in automotive component machining — cylinder blocks, transmission cases, pump bodies. The 60-tool ATC (expandable to 120) supports complex multi-face machining programs without tool change interruptions. A 90-degree APC (automatic pallet changer) enables continuous machining with pallet swap times of approximately 16 seconds chip-to-chip.

The KH63G's double-column construction provides high rigidity for the aggressive feedrates and depths of cut that justify the HMC investment over VMC alternatives. Rapids of 40/40/40 m/min are fast for an HMC of this class, reducing positioning time between features on complex prismatic workpieces. The Fanuc 31i-B control is standard, with full 4-axis control (B-axis rotary table) for 4-sided machining in a single setup.

At $350,000-$500,000 new, the KH63G is priced below equivalent 630 pallet HMCs from Okuma, Mazak, and Makino while offering the build quality and performance that production environments require. Korean manufacturing efficiency and favorable pricing allow Hyundai WIA to compete effectively in the premium HMC segment.
