High rigidity vertical machining center for die and mold
SIRIUS 650 to 1050
Built to order. Ask for lead time.

Overview
650 mm Y-axis, box ways and a gear-driven 50-taper spindle
The SIRIUS-650 is a C-frame vertical machining center for die and mold work, with box ways on all three axes and a gear-driven 50-taper spindle. The standard 5,000 rpm spindle shifts through three gear ranges for 1,145 Nm of torque, and an 8,000 rpm version is available. Travel is 1,300 / 650 / 650 mm over a 1,800 x 650 mm table rated for 1,500 kgf. It comes with a 24-tool ATC or without one.

Features
- 01Scraped box ways on all axesAll three axes run on box ways, and the Y-axis slideway is widened for support and lower friction. The ways are precision scraped to absorb vibration and give smooth, precise movement.
- 02Gear-driven spindleThe standard 5,000 rpm spindle shifts automatically through three gear ranges and delivers 1,145 Nm (30 min). The 8,000 rpm option uses two ranges and delivers 316 Nm (30 min).
- 03Grease or oil-jet spindle lubricationThe 5,000 rpm spindle uses grease-lubricated bearings with the bearing assembly and gear housing jacket cooled by circulating oil. The 8,000 rpm spindle uses oil-jet lubrication with jacket cooling.
- 04C-frame with crane accessThe C-type frame and wide work area give direct access to the table, and large workpieces can be loaded and unloaded by crane.
- 05With or without ATCThe machine ships with a 24-tool memory random ATC, or without an ATC at 11,700 kgf instead of 12,200 kgf.
- 06Hwacheon 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.
