Hwacheon SIRIUS-2500 vs Hwacheon Vesta 1000
Hwacheon vs Hwacheon · Vertical Machining Centers
Summary
The Hwacheon SIRIUS-2500 and the Hwacheon Vesta 1000 are both Hwacheon vertical machining centers, but they serve different jobs. The SIRIUS-2500 is a large double-column mold and die machine with 3,100 mm (122.0 in) of X travel, 4,000 mm on the L version, and 2,300 mm of Y travel. The Vesta 1000 is a job-shop VMC with 1,000 x 550 x 500 mm of travel.
The SIRIUS-2500 adds 900 mm of Z travel, an ISO #50 (BBT-50) spindle, 40 tools and a Fanuc 31i-B control, on a machine weighing 39,700 kg. The Vesta 1000 uses a BT40 spindle, a 30-position ATC and a Fanuc 0i-MF Plus, and weighs 6,500 kg. Both list 30 / 25 kW spindle power and 12,000 rpm, though the SIRIUS reaches that speed only in its 12K version; the 8K version runs to 8,000 rpm.

Advantages
Hwacheon SIRIUS-2500
- 3,100 mm (122.0 in) X travel, or 4,000 mm (157.5 in) on the L version, against 1,000 mm (39.4 in)
- 2,300 mm (90.6 in) Y travel and 900 mm (35.4 in) Z travel against 550 mm and 500 mm
- Table of 3,300 x 2,000 mm on the 8K version against 1,100 x 500 mm
- ISO #50 (BBT-50) spindle taper against BT40
Hwacheon Vesta 1000
- 12,000 RPM as standard, where the SIRIUS-2500 8K version runs to 8,000 rpm
- A 6,500 kg (14,330 lb) machine against 39,700 kg (87,523 lb)
- Same 30/25 kW (40/33 hp) spindle rating in a machine sized for medium-to-large job-shop parts
Verdict
These machines do different jobs. Choose the Hwacheon SIRIUS-2500 for large molds, dies, plates and weldments that need 3,100 mm or more of X travel, 2,300 mm of Y travel between the columns and a 50-taper spindle. Choose the Hwacheon Vesta 1000 for medium-to-large steel and aluminum job-shop parts that fit within 1,000 x 550 x 500 mm, where a 6,500 kg machine with the same 30/25 kW spindle rating does the work without the size of a 39,700 kg double-column machine.
