HYUNDAI WIA KH50G HORIZONTAL MACHINING CENTER

Technical Description

The Hyundai WIA KH50G is a robust horizontal machining center engineered for heavy-duty cutting operations and maximum productivity. It features a 19.7" × 19.7" pallet with a maximum load capacity of 1,764 lbs and incorporates a shuttle-type automatic pallet changer with dual pallets for continuous operation. The machine is equipped with a 2-step geared main spindle delivering 4,500 RPM with optional 8,000 RPM capability, generating 24.8 HP (30-minute rating) or up to 29.5 HP optionally, with torque ratings of 664.5 lbf·ft to 789.9 lbf·ft depending on configuration. The spindle utilizes BT50 taper with an oil cooling system for precision and thermal stability. A Fanuc 31i-Model A CNC control (with optional Siemens compatibility) manages operations, featuring custom macro capabilities, coordinate rotation, helical and polar interpolation, and embedded Ethernet connectivity. The machine provides three-axis travel of 29.9" (X), 27.8" (Y), and 25.6" (Z) with rapid traverse rates of 787 ipm across all axes. A standard 90-tool magazine (expandable to 120 tools) accommodates tool diameters up to 245 mm with quick 5.5-second tool change times. The KH50G incorporates box guides on all axes for ultra-rigidity, a specially designed column that minimizes thermal displacement, and an air semi-rising slideway on the Z-axis to prevent table sag during heavy machining. High-pressure coolant delivery through the spindle at 1,000 psi ensures superior surface finishes and chip evacuation via integrated conveyor system.
