Technical Description
The Hyundai Wia KH1000 is a heavy-duty horizontal machining center engineered for large-scale, high-precision metalworking applications. It features dual pallets measuring 39.37 x 39.37 inches (1,000 x 1,000 mm), each supporting a load capacity of up to 6,613 lbs (3,000 kg), enabling the handling of substantial workpieces. The machine offers an extensive X, Y, and Z axis travel of approximately 82.7", 53.1", and 55.1" respectively (2,100 x 1,350 x 1,400 mm), providing a large machining envelope for complex components. The spindle is powered by a robust 35 HP (26 kW) motor capable of speeds up to 8,000 RPM, using a CAT50 (Big Plus dual contact) taper with a 2-step geared head to deliver high torque of up to 595 lb-ft, ensuring efficient heavy cutting performance. Coolant delivery is managed through the spindle with a pressure of 435 psi, improving tool life and chip evacuation. The machine includes a 60-position automatic tool changer (ATC) for versatile machining, with a chip-to-chip tool change time as low as 16.7 seconds. Pallet indexing is precise to within 1°, facilitated by a shuttle-type automatic pallet changer system that minimizes downtime with pallet change cycles around 110 seconds. The KH1000 integrates advanced box guideways on all axes and employs a spindle oil cooling system for thermal stability, enhancing machining accuracy. High-speed rapid traverse rates of 787 inches per minute on all axes optimize productivity. The control system is typically a Fanuc 31i-B CNC, offering advanced programming capabilities and ease of operation, making the KH1000 suitable for demanding production environments requiring heavy-duty horizontal machining.
