Advantages
Okuma GENOS L400II
- Superior bar capacity at 76 mm (3 in) vs 51 mm (2.0 in)
- Superior max turning diameter at 400 mm (15.7 in) vs 260 mm (10.2 in)
- Superior max turning length at 500 mm (19.7 in) [1,000 / 1,500 mm optional] vs 250 mm (9.8 in) per spindle
- Superior x axis travel at 215 mm (8.5 in) vs 200 mm (7.9 in) per turret
- Superior z axis travel at 580 mm (22.8 in) vs 350 mm (main) / 310 mm (sub)
Okuma LAW-2S
- Faster rapid traverse at 30 m/min (all axes) reduces non-cutting time between operations
- Superior machine weight at 7,200 kg (15,873 lb) vs 5,900 kg (13,007 lb)
- Backed by Okuma's dealer and service network for parts and support
- Production shops that currently run OP10 and OP20 on separate lathes and want to consolidate into a single machine for complete parts
Verdict
The Okuma GENOS L400II holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the Okuma GENOS L400II's strengths in areas like Bar Capacity and Max Turning Diameter align with your work, it's the clear pick. The Okuma LAW-2S 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.
