The price estimate for the Hwacheon SIRIUS-UM+ is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/hwacheon-sirius-um-plus#price; the request is passed to Hwacheon or an authorised dealer.
The 20K BBT-40 spindle runs to 20,000 rpm at 18.5 / 11 kW (24.8 / 14.8 hp) or, in its stronger version, 37 / 18.5 kW (49.6 / 24.8 hp), and takes tools up to 8 kg (18 lb). The 32K HSK-E40 spindle runs to 32,000 rpm at 18.5 / 13 kW (24.8 / 17.4 hp) but takes tools only up to Ø50 mm (Ø2.0 in) and 1.5 kg (3 lb).
BBT-40 as standard, with CAT-40, SK-40 or HSK-A63 as options. Tools may be up to Ø75 mm (Ø3.0 in) with adjacent pockets filled or Ø150 mm (Ø5.9 in) with them empty, 300 mm (11.8 in) long and 8 kg (18 lb). The pull stud is MAS P40T-1 (45°).
The SIRIUS-UL+ has a larger 1,200 x 600 mm (47.2 x 23.6 in) table rated 800 kg (1,764 lb), spindles at 12,000, 14,000, 20,000 or 24,000 rpm and weighs 11,800 kg (26,014 lb). The SIRIUS-UM+ is smaller, with an 850 x 500 mm (33.5 x 19.7 in) table, and is the one with the 32,000 rpm option.
30 as standard, with 40 or 60 as options. Tools are selected by memory random. A larger magazine matters on mould work, where many small finishing tools and sister tools sit alongside the roughing cutters.
A floor space of 2,585 x 3,200 mm (101.8 x 126.0 in), 2,950 mm (116.1 in) of height and a floor for 8,000 kg (17,637 lb). It takes 55 kVA and air at 0.5 to 0.7 MPa x 1,100 NL/min. The coolant tank holds 250 L (66 US gal).
