How much does the Okuma LU45II 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 LU45II is a large CNC lathe: 25.59 in maximum turning diameter, a 118 mm (4.6 in) bar capacity through an A2-11 spindle nose, and a 50/40 hp spindle. Turning length is where the model spreads out. The standard figure is 29.53 in, and Okuma lists 39.37, 78.74 and 118.11 in versions in brackets.
At 118.11 in the turning length is four times the standard one, on the same diameter and the same spindle. Work that long on a lathe of this swing normally depends on a tailstock and steady rests. None of that is in the headline table, so ask what the longer versions include.
The spindle runs 12 to 2,800 rpm, with a 12 to 2,400 rpm range as the listed option. The upper turret has 12 stations and the table gives no row for a lower turret. Among Okuma's other lathes, the LB45III lists the same 118 mm (4.6 in) bar capacity and the same 50/40 hp, so the choice between them rests on the turret arrangement and the bed lengths offered.

Strengths & Limitations
Strengths
- Turning length options of 29.53, 39.37, 78.74 and 118.11 in on one model
- 118 mm (4.6 in) bar capacity through an A2-11 spindle nose
- 25.59 in maximum turning diameter, against 21.65 in on the LU35II at the same 50/40 hp
Limitations
- Top speed is 2,800 rpm, or 2,400 rpm on the optional range, against 3,200 rpm on the LU35II
- The 50/40 hp rating is the same as the smaller LU35II, so the larger diameter does not come with more power
- No lower-turret, chuck size or driven-tool rows in Okuma's headline table

Frequently Asked Questions
01
Four are listed. The standard maximum turning length is 29.53 in, and 39.37, 78.74 and 118.11 in appear in brackets as optional versions. Turning diameter (25.59 in), spindle rating (50/40 hp) and bar capacity (118 mm, 4.6 in) are given once for all of them.
02
118 mm (4.6 in), through an A2-11 spindle nose. The spindle runs 12 to 2,800 rpm as standard, with a 12 to 2,400 rpm range listed as an option, and is rated 50/40 hp.
03
The LU45II is the larger of the two: 25.59 in maximum turning diameter against 21.65 in on the LU35II. Both are rated 50/40 hp with 49 / 66 fpm rapid traverse and a 12-station upper turret. The LU35II's standard spindle is faster at 14 to 3,200 rpm, and its standard nose is A2-8 where the LU45II has A2-11.
