Hwacheon SIRIUS-UL+

High-speed vertical machining center

SIRIUS U Series

Built to order. Ask for lead time.

Overview

600 mm Y-axis, 37 kW spindles from 12,000 to 24,000 rpm

The SIRIUS-UL+ is a high-speed, double-column vertical machining center with a 600 mm Y-axis, built for die and mold work that needs heavy roughing and fine finishing on the same machine. Hwacheon raised feed drive and structural rigidity 30% over the previous model, and the spindle bearings are oil-jet lubricated with a jacket-cooled motor housing to limit thermal growth. Travel is 1,050 / 600 / 550 mm over a 1,200 x 600 mm table rated for 800 kgf, with 36 m/min rapids. The 37 kW built-in spindle runs 20,000 rpm as standard, with 12,000, 14,000 and 24,000 rpm versions.

Features

0137 kW spindles from 12,000 to 24,000 rpmThe standard 20,000 rpm built-in spindle makes 37 kW and 221 Nm on BBT-40. Options are 12,000 rpm, 14,000 rpm (303 Nm) and 24,000 rpm, which takes HSK-A63 tooling only.
0230% stiffer feed drive and structureHwacheon raised the rigidity of the feed drive and the machine structure by 30% over the earlier SIRIUS-UL+. The X-axis LM guide was widened for roughing.
03Oil-jet bearing coolingOil is jetted directly onto the front and rear spindle bearings, and the motor housing and front bearing are jacket cooled to limit thermal displacement. Hwacheon assembles the spindle in its own clean room.
04Thermal displacement controlHSDC corrects the Z-axis error from taper expansion at high spindle speed, and HFDC reads sensors in the castings to correct frame displacement. Together they form HTDC, which is standard.
05Tool measuring outside the machining areaWhen the optional tool measuring system is fitted, the measuring unit sits outside the machining area, which leaves more of the table free for work.
06Hwacheon machining software standardHECC contour control, HTLD tool load detection and OPTIMA feed optimization are standard. HTLD measures load every 8 msec to catch worn or broken tools.
