Hwacheon SIRIUS-UM⁺
High-speed vertical machining center
SIRIUS U Series
Built to order. Ask for lead time.
Overview
500 mm Y-axis, built-in spindles up to 45,000 rpm
The SIRIUS-UM⁺ is the 500 mm Y-axis machine in Hwacheon's SIRIUS U Series, a bridge-type, double-column vertical machining center. It is built for precise die and mold work, with roller LM guides on all axes and cooling of the spindle and frame to hold thermal displacement over long runs. Travel is 750 / 500 / 450 mm over an 850 x 500 mm table rated for 800 kgf. The standard spindle runs 20,000 rpm on BBT-40, with 32,000 rpm (HSK-E40) and 45,000 rpm (HSK-E32) versions; the 20,000 and 32,000 rpm versions hold 30 tools (40 or 60 optional) and the 45,000 rpm version holds 20 (40 optional).

Features
- 01Built-in spindles from 20,000 to 45,000 rpmThe standard spindle is a 20,000 rpm air-oil built-in motor on BBT-40 (18.5 kW, 60 Nm). Hwacheon also lists a 20,000 rpm oil-jet version (37 kW, 221 Nm), 32,000 rpm on HSK-E40 and 45,000 rpm on HSK-E32.
- 02Roller LM guides and a stiffer X-axis screwAll axes run on high-rigidity roller LM guides. The X-axis ball screw has a shorter lead and a larger diameter, and X and Y servo power is 87% higher than the previous SIRIUS-UM.
- 03Bridge-type frame with a low baseThe bridge-type structure has 1,090 mm between columns. The base sits lower for rigidity and better control of vibration.
- 04Heat and vibration kept off the frameA detachable insulated cover limits frame deformation from coil conveyor vibration and from chip and coolant heat. Spindle and frame cooling hold thermal displacement down during long machining runs.
- 05Two coil conveyors under the tableTwo coil conveyors sit in a wide, steeply slanted slide cover under the table to carry chips out, and chips and coolant discharge separately to extend coolant tank life.
- 06Hwacheon machining software standardHTDC thermal displacement control, HECC contour control, HTLD tool load detection and OPTIMA feed optimization are standard. HTLD watches tool load to catch worn or broken tools before they damage the part.
