USED OKUMA LB4000 EX III

The Okuma LB4000 EX III is a flagship heavy-duty CNC horizontal turning center designed for machining large, complex components with high precision and productivity. As part of Okuma’s advanced LB EX III series, the machine is built on a rigid slant-bed box construction that provides exceptional stability, vibration resistance, and long-term accuracy. It incorporates Okuma’s Thermo-Friendly Concept, which minimizes thermal distortion and ensures consistent machining accuracy during extended production cycles.

The machine offers a maximum turning diameter of approximately 480 mm and a turning length ranging from 750 mm up to 2,150 mm depending on configuration, making it suitable for industries such as oil & gas, aerospace, and heavy engineering. Spindle speeds reach up to 4,200 rpm, supported by a high-torque PREX motor that enables both heavy roughing and high-speed finishing operations.

A standard 12-station turret is complemented by optional configurations including live tooling, Y-axis, and sub-spindle (MYW), allowing full multitasking capabilities in a single setup. The machine is equipped with the advanced OSP-P500 control, offering enhanced processing power, user-friendly operation, and seamless automation integration.

Overall, the LB4000 EX III is designed for manufacturers requiring high-capacity machining with precision, flexibility, and long-term reliability in demanding production environments.

WHY BUY USED OKUMA LB4000 EX III

Buying a used Okuma LB4000 EX III is an excellent option for manufacturers that require large-part machining capability while optimizing capital investment. As a flagship model, this machine is engineered with heavy-duty construction and advanced thermal stability systems, allowing it to maintain precision and performance even after extensive use. Its durability and reliability make it highly attractive in the secondary CNC market.

Cutting time (spindle hours) is one of the most important factors when evaluating a used unit. Machines with low cutting hours—typically under 5,000–7,000 hours—are considered lightly used and can perform close to new condition. Units with moderate usage (7,000–18,000 hours) remain dependable for most production requirements if properly maintained. Machines exceeding 18,000–25,000 hours may require servicing of components such as the spindle, turret, or guideways, but they can still provide strong value for less intensive operations.

Another advantage is that even used LB4000 EX III machines include modern features such as OSP-P500 controls, automation compatibility, and multitasking capabilities like live tooling and Y-axis. This allows integration into current production workflows without major upgrades.

For companies handling large or heavy components, a used LB4000 EX III offers a powerful combination of capacity, reliability, and cost efficiency.

HOW MUCH DOES A USED OKUMA LB4000 EX III COST?

The cost of a used Okuma LB4000 EX III depends on manufacturing year, configuration, condition, and especially cutting time. Since this model was introduced around 2024, pricing is primarily driven by usage, features, and machine condition rather than older pre-2000 or early-generation categories.

For very new machines (2024–2025), prices typically range from $140,000 to $250,000 depending on configuration, automation systems, and included tooling. These machines generally have very low cutting hours (under 3,000–5,000) and are close to new condition.

Machines with moderate usage (2024–2025 units with 5,000–12,000+ cutting hours) may fall in the $100,000 to $160,000 range. These represent strong value options, offering advanced capabilities such as Y-axis, sub-spindle, and live tooling at a reduced price compared to new machines.

Heavily used machines (10,000–20,000+ hours) may drop below $100,000 depending on wear, maintenance history, and included features. However, due to the machine’s recent introduction, the availability of such units is still limited in the market.

Cutting time remains the most critical pricing factor—machines with lower spindle hours command premium value. Buyers should also evaluate maintenance records, tooling packages, and automation integration to determine the true investment and long-term return.
