Machine Comparison
Okuma GENOS L400II vs Okuma LAW-2S
Okuma vs Okuma · CNC Lathes
Summary
The Okuma GENOS L400II and the Okuma LAW-2S share a JIS A2-8 spindle nose and a 3,000 rpm top speed, but they serve different jobs. The GENOS L400II is a lathe for chucked parts and shafts up to 330 mm (12.99 in) in turning diameter. The LAW-2S is a two-turret production machine for large-diameter parts up to Ø24.80 in.
The LAW-2S has far more spindle power, 55/45 kW (75/60 hp) against 11 kW (15 hp), in a speed range of 200–3,000 rpm. The GENOS L400II starts lower, at 30–3,000 rpm, and has the faster rapids at 20 / 30 m/min against 20 / 15 m/min.

Advantages
Okuma GENOS L400II
- Rapids of 20 / 30 m/min against 20 / 15 m/min
- Spindle range starts at 30 rpm against 200 rpm, for slower cuts in steel and cast iron
- Sized for chucked parts and shafts within 330 mm (12.99 in) of turning diameter
Okuma LAW-2S
- Turning diameter up to Ø24.80 in against 330 mm (12.99 in)
- 55/45 kW (75/60 hp) spindle against 11 kW (15 hp)
- Two turrets cutting at once to shorten the cycle
Verdict
These machines do not compete for the same work. The Okuma LAW-2S is for volume production of large-diameter parts in free-cutting materials, where 55/45 kW (75/60 hp) and two turrets cutting at once shorten the cycle. The Okuma GENOS L400II is for shops turning chucked parts and shafts within 330 mm (12.99 in) in steel and cast iron, where its 11 kW (15 hp) spindle and 30–3,000 rpm range are enough.
