The Okuma MULTUS B250II is a high-performance multi-tasking CNC machine that integrates turning, milling, drilling, and material handling into a single platform, allowing complex parts to be completed in one setup. Designed as part of Okuma’s MULTUS B-series, it combines the functionality of a CNC lathe and machining center, significantly reducing setup time and improving overall productivity.
The machine features a 225° B-axis milling head and a high-speed milling spindle capable of reaching 12,000 rpm (optional 20,000 rpm), providing excellent flexibility for multi-axis machining. The main spindle typically reaches speeds up to 5,000 rpm and supports a maximum turning diameter of approximately 600 mm with a turning length of up to 750 mm, making it suitable for medium-sized complex components.
A standard automatic tool changer (ATC) with 40 tools (expandable to 60) enhances efficiency, while options such as sub-spindle (W version), Y-axis travel, and automation systems like ARMROID increase production capability.
Equipped with Okuma’s OSP control and Thermo-Friendly Concept, the MULTUS B250II ensures stable accuracy, ease of operation, and reduced thermal distortion. Overall, it is a versatile solution for high-mix, precision manufacturing environments requiring flexibility and reduced cycle times.

WHY BUY USED OKUMA MULTUS B250II
Buying a used Okuma MULTUS B250II is a strategic decision for manufacturers seeking advanced multi-tasking capability at a lower capital cost. These machines are engineered for durability and long-term precision, making them reliable even after extended use in demanding production environments.
A critical factor when evaluating a used unit is cutting time (spindle hours). Machines with low cutting hours—typically under 5,000–7,000 hours—are considered lightly used and can deliver near-new performance. Units with moderate usage (7,000–18,000 hours) remain dependable for most applications if properly maintained. Machines with higher cutting hours (18,000+ hours) may require servicing of components such as the milling spindle, B-axis head, or axis drives, but they can still provide strong value for less complex operations.
One of the biggest advantages of the MULTUS B250II is its ability to combine multiple processes in one machine. Even older units retain features such as B-axis milling, Y-axis movement, and optional sub-spindle, enabling complete part machining in a single setup. This reduces labor, setup time, and work-in-progress inventory.
Additionally, Okuma’s reputation for reliability, thermal stability, and long service life reduces the risk typically associated with used equipment. For manufacturers producing complex parts, a used MULTUS B250II offers premium capability at a significantly reduced investment.
HOW MUCH DOES A USED OKUMA MULTUS B250IICOST?
The cost of a used Okuma MULTUS B250II varies depending on manufacturing year, configuration, condition, and especially cutting time. Since the model was introduced around the mid-2010s, pricing is generally segmented by age and usage rather than older pre-2000 categories.
For early-generation machines (2015–2017), prices typically range from $70,000 to $120,000. These units often have higher cutting hours (12,000–25,000+) and may require maintenance or refurbishment, but they still offer full multi-tasking capability.
Machines built between 2018 and 2021 generally fall in the $120,000 to $200,000 range. These represent the most active used market segment and usually include moderate cutting hours (6,000–15,000), along with updated controls and improved automation compatibility.
For newer machines from 2022 to 2025, prices can range from $200,000 to $350,000 or more depending on configuration, tooling packages, and automation systems. These machines typically have low cutting hours (under 5,000) and are close to new condition.
Cutting time significantly impacts pricing—machines with lower spindle hours command premium value regardless of age. Buyers should also evaluate features such as sub-spindle, tool capacity, and automation integration to determine the true overall investment and long-term return.
