Machine Comparison
Haas CM-1 vs Okuma GENOS M460-VE
Haas Automation vs Okuma · Vertical Machining Centers
Summary
The Haas CM-1 and the Okuma GENOS M460-VE are both vertical machining centers, but they serve different jobs. The Haas CM-1 is a compact mill built around a 30,000 rpm ISO 20 spindle for micro-milling and engraving. The Okuma GENOS M460-VE is a larger BT40 machine with a 1,000 × 460 mm (39.37 × 18.11 in) table against 22.5 × 10 in (572 × 254 mm).
The Haas CM-1 runs twice the spindle speed, 30,000 rpm against 15,000 rpm. The Okuma has the power, 22/18.5 kW (30/25 hp) against 5 hp (3.7 kW), carries 32 tools against 20, and rapids at 40 m/min in X-Y and 32 m/min in Z against 757 ipm (19.2 m/min).

Advantages
Haas CM-1
- Twice the spindle speed: 30,000 rpm against 15,000 rpm
- ISO 20 spindle suited to small cutters, micro-milling and engraving
- Suits workshops and labs with only single-phase power
Okuma GENOS M460-VE
- 22/18.5 kW (30/25 hp) spindle against 5 hp (3.7 kW)
- Larger table: 1,000 × 460 mm (39.37 × 18.11 in) against 22.5 × 10 in (572 × 254 mm)
- 32 tools against 20
- Rapids of 40 m/min in X-Y and 32 m/min in Z against 757 ipm (19.2 m/min)
Verdict
Choose by part size and cutter size. The Haas CM-1 fits workshops and labs doing micro-milling, engraving and fine-detail finishing on small parts, where 30,000 rpm matters more than torque and single-phase power may be all that is available. The Okuma GENOS M460-VE fits a job shop cutting aluminum parts in vises and on fixture plates, where the BT40 spindle's 22/18.5 kW (30/25 hp), 32 tools and the 1,000 × 460 mm table do the work.
