Haas CM-1 vs Roku-Roku HC-658
Haas Automation vs Roku-Roku · Vertical Machining Centers
Summary
The Haas CM-1 and Roku-Roku HC-658 are both high-speed vertical machining centers for fine work, but the HC-658 is a larger machine in a different size class. The CM-1 is a compact ISO 20 micro-mill with 12 x 10 x 14 in of travel. The Roku-Roku HC-658 is an HSK-E40 electrode and mold-finishing machine with 23.6 x 19.6 x 15.7 in of travel and an 800 x 500 mm table.
The HC-658 leads on most rows: 32000 rpm against 30,000 rpm, 5.5 kW (7.4 HP) continuous against 5 hp (3.7 kW), 60 m/min (2,362 ipm) rapids against 757 ipm (19.2 m/min), and a 500 kg load against 150 lb (68 kg). Both hold 20 tools. The CM-1 weighs 2,200 lb (998 kg) against 5,500 kg (12,125 lb).

Advantages
Haas CM-1
- Much lighter machine at 2,200 lb (998 kg) against 5,500 kg (12,125 lb)
- Compact 22.5 × 10 in table for small parts
- Haas Next Generation Control
Roku-Roku HC-658
- 23.6 x 19.6 x 15.7 in travel against 12 x 10 x 14 in
- 500 kg (1,102 lb) table load against 150 lb (68 kg)
- 60 m/min (2,362 ipm) rapids against 757 ipm (19.2 m/min)
- 32000 rpm and 5.5 kW (7.4 HP) against 30,000 rpm and 5 hp (3.7 kW)
Verdict
The Haas CM-1 suits small medical, electronics and watch parts, engraving and R&D work, where a compact, light machine with a 30,000 rpm spindle is enough. The Roku-Roku HC-658 suits graphite and copper electrode production and fine mold-cavity finishing on larger parts, where its 800 x 500 mm table, 32000 rpm spindle and 60 m/min rapids justify a much bigger machine.
