Advantages
Hwacheon SIRIUS-2500
- Table of 3,300 x 2,000 mm (129.9 x 78.7 in) on the 8K version against 1,000 × 460 mm (39.37 × 18.11 in)
- 30 / 25 kW (40.2 / 33.5 hp) spindle against 22/18.5 kW (30/25 hp)
- 40 tools against 32, on a BBT-50 taper for roughing as well as finishing
Okuma GENOS M460-VE
- 15,000 rpm spindle against 8,000 rpm (8K) or 12,000 rpm (12K)
- BT40 tooling suited to aluminum and small-tool work
- 1,000 × 460 mm (39.37 × 18.11 in) table sized for vise and fixture-plate work
Verdict
Choose by part size. The Hwacheon SIRIUS-2500 is for wide plates, frames and heavy workpieces that need a table 2,000 mm (78.7 in) across, 50-taper tooling and 30 / 25 kW (40.2 / 33.5 hp) at the spindle. The Okuma GENOS M460-VE is for small and medium parts held in vises or on fixture plates, where 15,000 rpm and BT40 tooling matter more than table area. Few shops will weigh one against the other.
