OKUMA LB3000 EX-II – 2012
USED OKUMA LB3000 EX-II – 2012
The OKUMA LB3000 EX-II – 2012 is a high-performance CNC horizontal turning center designed for precision production machining. It belongs to Okuma’s SPACE TURN LB EX II family and combines a rigid slant-bed construction with a powerful spindle, large turning capacity, and Okuma’s OSP CNC control.
The LB3000 EX II platform was developed around high rigidity, thermal stability, and productivity. Okuma’s Thermo-Friendly Concept is intended to minimize thermal deformation during extended production, helping maintain dimensional consistency without relying heavily on lengthy warm-up cycles.
Depending on configuration, the LB3000 EX-II can be equipped as a conventional 2-axis turning center or with live tooling and Y-axis capability for milling, drilling, tapping, and other secondary operations. The documented platform specifications include approximately 260 mm of X-axis travel, up to 1,255 mm of Z-axis travel depending on bed configuration, 80 mm spindle bore, and spindle speeds up to 5,000 RPM.
A 2012 machine may also differ from later LB3000 EX-II configurations, so the exact spindle, chuck, control, travel, turret, and options should be verified against the individual machine.

MY configurations are particularly useful for parts requiring milled flats, keyways, cross holes, off-center holes, tapped holes, and other secondary features that can be machined using Y-axis and driven tooling capabilities. Okuma specifically identifies keyway, plane, and other milling operations as applications for the Y-axis versions of the LB3000 EX II.
WHY CHOOSE OKUMA LB3000 EX-II
The OKUMA LB3000 EX-II is a strong choice for manufacturers looking for a rigid CNC turning center with excellent accuracy and the ability to handle demanding production workloads.
One of its major advantages is Okuma’s Thermo-Friendly Concept, which is designed to reduce dimensional changes caused by temperature variations during machining. Okuma reports dimensional stability of approximately 5 μm under its specified test conditions, helping the machine maintain accuracy during extended operation.
The platform is also available with multi-tasking capabilities. MY configurations combine Y-axis movement, C-axis control, and live tooling, allowing milling and drilling operations to be performed directly on the turned component.
Its rigid slant-bed construction provides a stable platform for cutting, while the 80 mm spindle bore provides useful bar-working capacity. The 12-station turret also provides adequate tooling flexibility for many production applications.
For manufacturers that value accuracy, rigidity, thermal stability, and process consolidation, the LB3000 EX-II remains a highly capable CNC turning platform.
WHY BUY USED OKUMA LB3000 EX-II – 2012
Buying a used OKUMA LB3000 EX-II – 2012 can give manufacturers access to a high-quality production CNC lathe at a significantly lower acquisition cost than a new machine.
A major benefit is that the LB3000 EX II platform can be configured for both conventional turning and more advanced multi-tasking work. Buyers should therefore verify exactly which version they are purchasing, particularly whether it includes live tooling, Y-axis, C-axis, sub-spindle, bar feeder, parts catcher, and high-pressure coolant.
For a used 2012 machine, buyers should carefully inspect the spindle, spindle bearings, turret, ballscrews, guideways, servo motors, CNC control, hydraulic system, coolant system, lubrication system, chuck, and electrical cabinet.
The spindle should be tested across its full operating range for vibration, bearing noise, temperature, and runout. The turret should be indexed through all positions, and driven-tool stations should be tested where applicable.
The X and Z axes should be checked for backlash, repeatability, positioning accuracy, and abnormal mechanical noise. If the machine has Y-axis capability, the Y-axis should also be tested throughout its travel.
A well-maintained LB3000 EX-II with a healthy spindle, accurate axes, functioning turret, reliable OSP control, complete tooling, and documented maintenance can provide excellent value for production machining.
HOW MUCH DOES A USED OKUMA LB3000 EX-II – 2012 COST?
The price of a used OKUMA LB3000 EX-II – 2012 depends heavily on configuration. A basic 2-axis machine will generally command less than an MY or MW configuration equipped with live tooling, Y-axis, sub-spindle, bar feeder, chip conveyor, and other automation.
Used-market listings for LB3000 EX-II machines show significant variation depending on configuration and condition. A later documented machine with 2,800 hours, 22 kW spindle power, 80 mm bar capacity, 5,000 RPM spindle speed, live tooling, sub-spindle, chip conveyor, and tool setter is listed on a price-on-request basis, illustrating the premium associated with highly equipped configurations.
| USED OKUMA LB3000 EX-II – 2012 CONDITION | ESTIMATED COST |
|---|---|
| As-Is / High Hours | $35,000 – $50,000 |
| Functional / Average Condition | $50,000 – $65,000 |
| Good Production Condition | $65,000 – $80,000 |
| Excellent / Well Equipped | $80,000 – $100,000 |
| Low Hours / MY/MW Configuration | $100,000+ |
For a 2012 OKUMA LB3000 EX-II in good working condition, a reasonable used-market estimate is approximately $55,000–$85,000 USD.
A machine equipped with Y-axis, live tooling, C-axis, sub-spindle, bar feeder, chip conveyor, tool setter, high-pressure coolant, and complete tooling can command a significant premium over a basic 2-axis configuration.
Best estimated listing value: $65,000–$85,000 USD.
