How much does the Okuma LB2000 EX III 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
Speed is what sets the Okuma LB2000 EX III apart in the LB range: the spindle runs 45–6,000 rpm, driven by an 11/7.5 kW (15/10 hp) motor. Okuma lists a maximum turning diameter of 430 mm (16.93 in), a maximum turning length of 300 mm (11.81 in) and 380 mm (15 in) of Z-axis travel.
Those numbers describe a machine for small and medium parts cut quickly. At 6,000 rpm, carbide stays at a productive surface speed on bar-sized diameters and in aluminium or brass, and 7.5 kW (10 hp) on the lower rating is enough for the depths of cut such parts take. It is not the pick for sustained heavy roughing near the full 430 mm diameter, where the LB2500 EX II brings 22/15 kW (30/20 hp).
The spindle nose is listed as STD 140, rapid traverse is 25/30 m/min and the control is the Okuma OSP-P300L. Turning length is short relative to diameter, 300 mm against 430 mm, so this is a chucker first. The LB4000 EX III is the model in the range with 750 mm (29.53 in) of length.

Strengths & Limitations
Strengths
- 45–6,000 rpm spindle speed range
- 430 mm (16.93 in) maximum turning diameter
- 25/30 m/min rapid traverse over 380 mm (15 in) of Z-axis travel
- Runs the Okuma OSP-P300L control
Limitations
- Spindle power is 11/7.5 kW (15/10 hp), half the 22/15 kW (30/20 hp) of the LB2500 EX II
- Maximum turning length is 300 mm (11.81 in), so shaft work is limited
- No chuck size, bar capacity or turret station count appears in Okuma's headline rows

Frequently Asked Questions
01
The speed range is 45–6,000 rpm and spindle power is 11/7.5 kW (15/10 hp). The spindle nose is listed as STD 140. The high top speed favours small diameters and non-ferrous materials.
02
Maximum turning diameter is 430 mm (16.93 in) and maximum turning length is 300 mm (11.81 in), with 380 mm (15 in) of Z-axis travel. The proportions suit chucked parts more than shafts.
03
The Okuma OSP-P300L. Rapid traverse is listed as 25/30 m/min. By comparison the LB3000 EX III is listed with the OSP-P500 control and a 22 kW (30 hp) spindle.
