How much does the Okuma GENOS L300 cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Okuma. Configuration moves it a long way.
Overview
The Okuma GENOS L300 is listed as a box-way lathe with an 8 in (203 mm) chuck: 300 mm of maximum turning diameter, 520 mm of maximum turning length and a 380 mm (15.0 in) swing over the bed. The figures here are the listed ones, so check them against the documentation of the specific machine before relying on them.
The spindle is listed at 4,000 rpm maximum with an 11 kW motor and a 65 mm (2.6 in) bore. For bar work the bore is the figure to look at, because usable bar size is always somewhat smaller than the bore once a draw tube is fitted, and the table gives no separate bar capacity. Tooling sits in a 10-station turret.
Box ways and the listed rapids belong together. Rapid traverse is 20 m/min in Z and 15 m/min in X, which is the usual trade with sliding ways: more damping in the cut, less speed between cuts. Weight follows from the same construction. The machine is listed at approx. 5,500 kg (12,125 lb), a figure that matters for rigging and floor loading.
Control is the Okuma OSP-P300L, and the Thermo-Friendly Concept is listed as standard. For comparison, the GENOS L250II is listed with rapids of 25/30 m/min, a 6 in (165 mm) chuck and the same 11 kW (15 hp).

Strengths & Limitations
Strengths
- Box ways are the listed guideway type, which adds damping in heavy and interrupted cuts
- 65 mm (2.6 in) spindle bore behind an 8 in (203 mm) chuck
- 520 mm maximum turning length on a 300 mm maximum turning diameter
- 10-station turret with a 4,000 rpm, 11 kW spindle
- Thermo-Friendly Concept listed as standard, with the Okuma OSP-P300L control
Limitations
- Rapid traverse is 20 m/min in Z and 15 m/min in X, below the 25/30 m/min listed for the GENOS L250II
- 11 kW is the only power figure listed; the table gives no torque and no continuous rating
- At approx. 5,500 kg (12,125 lb) the machine needs rigging and floor capacity planned before delivery
- No bar capacity is listed, only the 65 mm (2.6 in) spindle bore
