Hwacheon SIRIUS 2500/5AX VERTICAL MACHINING CENTER

The Hwacheon SIRIUS 2500/5AX is a large-scale vertical machining center designed for high-precision, multi-axis machining of complex and heavy workpieces. It features a robust portal-type structure with double columns for exceptional rigidity and stability, supporting a maximum table size of 129.9" x 78.7" (expandable to 157.48" x 78.7") and a workpiece weight capacity of up to 22,040 lbs. The machine is equipped with a vertical spindle utilizing a BT-40 taper (optional CAT 40), delivering a top speed of 15,000 RPM and 25 HP (30-minute rating) for high-performance cutting. Tooling is managed by a 40-tool automatic tool changer with a rapid 3.5-second tool change time and 10-second chip-to-chip cycle, with optional pallet changer support for two pallets to maximize uptime. The SIRIUS 2500/5AX offers five-axis capability, with X, Y, and Z travels of 122", 90.5", and 39.3" respectively (X-axis expandable), and a B-axis rotation of ±100°. All axes achieve a maximum feed rate of 315 ipm and rapid traverse of 630 ipm, ensuring fast and efficient machining cycles. The direct-drive rotary axes provide high-precision angle division and high-speed rotation, minimizing backlash and maximizing accuracy. This machining center is ideal for demanding applications in mold, die, aerospace, and automotive industries, combining large work envelope, high load capacity, and advanced multi-axis functionality for superior productivity and precision.
