Okuma vs Okuma · CNC Lathes
Summary
The Okuma GENOS L2000-e and the Okuma GENOS L250II are small Okuma lathes with the same JIS A2-6 spindle nose and the same 25/30 m/min rapids. They differ in the shape of part they take: the GENOS L2000-e is the longer, faster machine, and the GENOS L250II is the one with the larger turning diameter.
The GENOS L2000-e turns 500 mm (19.69 in) of length against 290 mm (11.42 in), runs 45–5,000 rpm against 30–3,000 rpm and has a 15 kW (20 hp) spindle against 11 kW (15 hp). The GENOS L250II turns 280 mm (11.02 in) in diameter against 230 mm (9.06 in).

Advantages
Okuma GENOS L2000-e
- 500 mm (19.69 in) turning length against 290 mm (11.42 in)
- Spindle speed to 5,000 rpm against 3,000 rpm
- 15 kW (20 hp) spindle against 11 kW (15 hp)
Okuma GENOS L250II
- 280 mm (11.02 in) turning diameter against 230 mm (9.06 in)
- Sized for short chucked parts such as flanges, discs and bushes
Verdict
Pick the Okuma GENOS L2000-e for bar-fed and slim parts: it has the 5,000 rpm that small diameters need, 500 mm (19.69 in) of turning length and the stronger 15 kW (20 hp) spindle. Pick the Okuma GENOS L250II when the work is short chucked parts such as flanges, discs and bushes that need its 280 mm (11.02 in) turning diameter and stay within 3,000 rpm and 290 mm (11.42 in) of length.
