Hwacheon SIRIUS-1250
High rigidity vertical machining center for die and mold
SIRIUS-1250 to 2500
Built to order. Ask for lead time.
Overview
1,250 mm Y-axis bridge-type machine with a 5,000 kgf table
The SIRIUS-1250 is a bridge-type, double-column vertical machining center for large mold work. Its symmetrical portal structure spreads vibration, weight and heat evenly, and the feed system runs on box ways with Hwacheon's air floating system. Travel is 2,500 / 1,250 / 750 mm over a 2,800 x 1,250 mm table rated for 5,000 kgf, and the maximum material size is 1,535 mm wide by 775 mm high. The 30 / 25 kW BBT-50 built-in spindle runs 8,000 rpm as standard or 12,000 rpm as an option, with an 8-tool magazine standard and 40 tools optional.

Features
- 01Symmetrical portal structureThe bridge-type portal spreads vibration, upper weight and heat evenly through the frame. The distance from the Y-axis to the tool contact point is kept short for rigidity and precision.
- 02Built-in oil-jet spindleThe BBT-50 built-in motor spindle runs 8,000 rpm as standard or 12,000 rpm as an option at 30 / 25 kW, with oil-jet bearing lubrication and jacket cooling.
- 038-tool or 40-tool magazineThe standard magazine holds 8 tools with fixed address selection. A 40-tool memory random magazine is optional.
- 04Linear scales standardLinear scales on X, Y and Z are standard. A 225 mm high-column gap and a 90 mm Y-axis stroke extension are optional.
- 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.
