Overview
Four turning lengths make the Okuma LB35III a shaft lathe as much as a chucker. Maximum turning length is 600 mm (23.62 in) as standard, and Okuma shows 850, 1,500 and 2,000 mm (33.46, 59.06 and 78.74 in) in brackets as options, all on a 460 mm (18.11 in) maximum turning diameter. The Z-axis travel row, 600 mm (23.6 in), matches the standard length.
The spindle is offered in steps as well. Standard power is 30/22 kW (40/30 hp) with a 14–3,200 rpm range on an A2-8 nose. The options are 37/30 kW (50/40 hp), A2-11 and A2-15 noses, and two lower speed ranges, 12–2,800 and 40–1,400 rpm. Okuma's rows do not pair each speed range with a nose, but the pattern is a familiar one: a bigger nose and bore for larger bar and tube, paid for with a lower top speed. Chucks are 12 in (305 mm) or 15 in (381 mm).
The turret has 12 stations, rapid traverse is 15 / 20 m/min (591 / 787 ipm), and a C axis at 100 rpm appears in brackets as an option. Those rapids are slower than on the LB4000 EX III, which is listed at 30/30 m/min (1,181/1,181 ipm) with the same power options.

Strengths & Limitations
Strengths
- Turning length of 600 mm (23.62 in) as standard, with 850, 1,500 and 2,000 mm listed as options
- 30/22 kW (40/30 hp) standard spindle power, 37/30 kW (50/40 hp) optional
- A2-8 spindle nose as standard, with A2-11 and A2-15 as options
- 12-station turret and a 12 in (305 mm) or 15 in (381 mm) chuck
Limitations
- Top speed is 3,200 rpm on the standard spindle and falls to 2,800 or 1,400 rpm on the optional ranges
- Rapid traverse of 15 / 20 m/min (591 / 787 ipm) is slower than the 30/30 m/min of the LB4000 EX III
- The longer lengths, the higher power, the larger noses and the C axis are all options, not part of the base machine

Frequently Asked Questions
01
The standard maximum turning length is 600 mm (23.62 in). Okuma lists 850, 1,500 and 2,000 mm (33.46, 59.06 and 78.74 in) as options. Maximum turning diameter is 460 mm (18.11 in) on all of them.
02
Standard is 30/22 kW (40/30 hp), 14–3,200 rpm, on an A2-8 nose. The options listed are 37/30 kW (50/40 hp), A2-11 and A2-15 noses, and speed ranges of 12–2,800 and 40–1,400 rpm. Ask Okuma which combinations go together.
03
The LB4000 EX III is listed with 480 mm (18.90 in) of turning diameter, 750 mm (29.53 in) of length and 30/30 m/min (1,181/1,181 ipm) rapids. The LB35III turns 460 mm (18.11 in) and is slower between cuts, but it is the one with length options up to 2,000 mm (78.74 in).
