SIRIUS U Series
Built to order. Ask for lead time.
Overview
750 mm Y-axis, 50-taper spindle, 2,500 kgf table
The SIRIUS-UX is the 750 mm Y-axis machine in Hwacheon's SIRIUS U Series, a double-column vertical machining center for large die and mold work. Its symmetrical structure spreads vibration, weight and heat evenly through the frame. Travel is 1,500 / 750 / 650 mm over a 1,650 x 750 mm table rated for 2,500 kgf, with 1,800 mm between columns. The BBT-50 built-in spindle runs 12,000 rpm as standard or 15,000 rpm as an option at 30 / 25 kW, with 40 tools standard and 60 optional.

Features
- 01Symmetrical frameThe symmetrical structure spreads vibration, upper weight and heat evenly through the frame. The distance from the X-axis feed system to the tool contact point is kept short for rigidity and precision.
- 0250-taper built-in spindle with oil-jet coolingThe BBT-50 built-in motor spindle runs 12,000 rpm as standard or 15,000 rpm as an option at 30 / 25 kW. Bearings are oil-jet lubricated and the motor housing is jacket cooled.
- 032,500 kgf table, 1,800 mm between columnsThe 1,650 x 750 mm table carries 2,500 kgf, with 1,800 mm between the columns and 175 to 825 mm from table to spindle gauge plane.
- 04Index table optionHwacheon's index table runs without a separate 4-axis interface, with 4.3 tons of clamping force and 5 degree indexing.
- 05Hwacheon machining software standardHTDC thermal displacement control, HECC contour control, HTLD tool load detection and OPTIMA feed optimization are standard. HTLD measures load every 8 msec to catch worn or broken tools.
