USED OKUMA V920EX

The Okuma V920EX is a heavy-duty vertical CNC turning center designed for machining large-diameter, thin-walled, and irregularly shaped components with high stability and precision. As part of Okuma’s V-series vertical lathe lineup, it features a rigid box-type base and column structure that ensures excellent rigidity, vibration damping, and long-term machining accuracy.

The machine offers a maximum turning diameter of approximately 920 mm and a maximum turning height of 860 mm, making it suitable for large components such as pump housings, flanges, valves, and industrial rotors. Its vertical design allows the workpiece to be supported by gravity on the chuck face, reducing deformation and improving accuracy, especially for thin or unbalanced parts.

The spindle typically reaches speeds up to 1,250 rpm, powered by a high-torque motor around 30 kW, enabling stable heavy cutting as well as precision finishing. A 12-station turret provides efficient tool changing, and optional milling capability (M function) expands its multitasking potential for complex operations.

The V920EX is also designed with efficient chip evacuation, optional conveyor systems, and Okuma’s Thermo-Friendly Concept, which helps maintain dimensional stability during long production cycles. Overall, it is built for high-rigidity, large-part machining where stability and accuracy are critical.

WHY BUY USED OKUMA V920EX

Buying a used Okuma V920EX is a strong choice for manufacturers who machine large, heavy, or irregular components but want to avoid the high cost of a new vertical turning center. These machines are built with extremely rigid structures, meaning even older units retain strong machining capability if properly maintained.

Cutting time (spindle hours) is a key evaluation factor. Machines with low usage (under 5,000–7,000 hours) are considered lightly used and typically perform close to new condition. Units with moderate usage (7,000–18,000 hours) are still reliable for most production work if maintenance has been consistent. Higher usage machines (18,000–30,000+ hours) may require attention to spindle bearings, turret wear, or hydraulic systems, but can still be valuable for less precision-critical applications.

One of the biggest advantages of the V920EX is its vertical orientation. Gravity helps stabilize large or thin workpieces, reducing distortion and improving machining accuracy. Even used machines retain this core advantage, making them highly effective for large flanges, pump bodies, and similar components.

Okuma’s reputation for durability, thermal stability, and long machine life further reduces risk when buying used. For shops needing large-part capability without new-machine investment, the V920EX offers excellent long-term value.

HOW MUCH DOES A USED OKUMA V920EX COST?

The cost of a used Okuma V920EX depends heavily on manufacturing year, configuration, condition, and cutting time. Since this model has been in production since around 2016, pricing is generally divided into age-based segments rather than older legacy categories.

For early machines (2016–2018), prices typically range from $80,000 to $160,000. These units often have higher cutting hours (12,000–30,000+) and may require servicing of spindle or turret components, but they still offer full heavy-duty vertical turning capability.

Machines built between 2019 and 2022 generally fall in the $160,000 to $280,000 range. These represent the most active used-market segment and typically have moderate cutting hours (6,000–15,000), along with updated controls and optional milling features.

For newer machines from 2023 to 2025, prices can range from $280,000 to $450,000+ depending on configuration, tooling, and automation integration. These machines usually have low cutting hours (under 5,000) and are close to new condition.

Cutting time is one of the strongest pricing drivers—lower spindle hours significantly increase value regardless of age. Buyers should also evaluate turret condition, spindle health, and maintenance history to determine true machine value and expected production life.
