USED OKUMA LB4000 EX II

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

The LB4000 EX II offers a maximum turning diameter of approximately 480 mm and a turning length of up to 2,150 mm depending on configuration, making it ideal for industries such as oil & gas, aerospace, and heavy engineering. It is equipped with a high-torque PREX motor and spindle speeds up to around 4,200 rpm, enabling both heavy-duty roughing and high-speed finishing operations.

A standard 12-station turret is complemented by optional configurations including live tooling, Y-axis, and sub-spindle setups, allowing for multitasking capabilities in a single setup. The machine also features Okuma’s OSP control system, which is known for ease of use and seamless automation integration. Overall, the LB4000 EX II is a powerful and versatile turning solution for high-capacity machining environments.

WHY BUY USED OKUMA LB4000 EX II

Buying a used Okuma LB4000 EX II is a practical choice for manufacturers that require large-part machining capability without investing in a new high-cost machine. These machines are built with heavy-duty construction and advanced thermal control systems, allowing them to maintain accuracy and reliability even after long production cycles. Their robust design makes them particularly attractive in the secondary market.

Cutting time (spindle hours) is one of the most critical 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 reliable for most production applications if properly maintained. Machines exceeding 18,000–25,000 hours may require servicing of key components such as the spindle, turret, or guideways but can still offer strong value for less demanding operations.

Another advantage is that even older LB4000 EX II machines often include advanced features such as live tooling, large bore capacities, and automation compatibility. This allows manufacturers to handle complex and large components without upgrading to newer multi-tasking machines.

For shops working with heavy or long parts, a used LB4000 EX II provides a strong combination of power, durability, and cost efficiency.

HOW MUCH DOES A USED OKUMA LB4000 EX II COST?

The cost of a used Okuma LB4000 EX II varies based on manufacturing year, configuration, condition, and especially cutting time. Since this model was introduced in the 2010s, pricing is generally segmented by age and usage rather than very old pre-2000 machines.

For early machines (2010–2014), prices typically range from $30,000 to $60,000. These units often have higher cutting hours (12,000–25,000+) and may require maintenance or refurbishment depending on usage history.

Machines built between 2015 and 2019 generally fall in the $60,000 to $110,000 range. These represent the most common used inventory and usually include moderate cutting hours (6,000–18,000), along with improved controls and optional features such as live tooling or sub-spindle configurations.

For newer machines from 2020 to 2025, prices can range from $110,000 to $200,000 or more depending on configuration, automation integration, and included tooling packages. These machines typically have low cutting hours (under 5,000) and are close to new condition.

Cutting time plays a major role in pricing—machines with lower spindle hours command premium value regardless of age. Buyers should also consider maintenance records, tooling, and automation features to determine the true investment and long-term return.
