- Tighter positioning accuracy at ±0.005 mm for precision-critical work
Roku-Roku HC-658
- Greater y travel of 500 mm (19.7 in) accommodates larger workpieces
- Faster rapid traverse at 60 m/min (2,362 ipm) all axes reduces non-cutting time between operations
- Superior machine weight at 5,500 kg (12,125 lb) vs 4,800 kg (10,582 lb)
Verdict
The Okuma GENOS M460-VE holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the Okuma GENOS M460-VE's strengths in areas like X Travel and Z Travel align with your work, it's the clear pick. The Roku-Roku HC-658 may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
