Haas CM-1 vs Hwacheon SIRIUS-2500
Haas Automation vs Hwacheon · Vertical Machining Centers
Summary
The Haas CM-1 and Hwacheon SIRIUS-2500 are both vertical machining centers, but they serve different jobs at opposite ends of the size range. The CM-1 is a compact ISO 20 micro-mill with 12 x 10 x 14 in of travel and a 150 lb (68 kg) load. The SIRIUS-2500 is a large BBT-50 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 Hwacheon carries 10,000 kg (22,046 lb), or 15,000 kg on the L, has 30 / 25 kW (40.2 / 33.5 hp) against 5 hp (3.7 kW), and holds 40 tools against 20 on a Fanuc 31i-B control. The CM-1 spins to 30,000 rpm against 8,000 rpm (8K) or 12,000 rpm (12K).

Advantages
Haas CM-1
- 30,000 rpm spindle against 8,000 rpm (8K) or 12,000 rpm (12K)
- Compact machine at 2,200 lb (998 kg) against 39,700 kg (87,523 lb)
- Haas Next Generation Control for small-part programming
Hwacheon SIRIUS-2500
- 3,100 x 2,300 x 900 mm travel against 12 x 10 x 14 in
- 10,000 kg (22,046 lb) table load, 15,000 kg on the L, against 150 lb (68 kg)
- 30 / 25 kW (40.2 / 33.5 hp) spindle against 5 hp (3.7 kW)

Verdict
These machines do different jobs. The Haas CM-1 is for small precision parts, engraving and micro-milling, where 30,000 rpm and a small footprint suit medical, watch and electronics work. The Hwacheon SIRIUS-2500 is for large molds, dies, heavy plates and weldments up to 2,300 mm wide and 10,000 kg, where a 50-taper spindle and multi-meter travel are required.
