The Okuma MULTUS U4000 is a high-end multi-tasking CNC machine designed for complex, high-precision machining by combining turning, milling, drilling, and 5-axis operations in a single platform. As part of Okuma’s advanced MULTUS U-series, it features a rigid flat-bed structure with a traveling column design, providing excellent stability and accuracy for large and complex components.
The machine supports a maximum turning diameter of approximately 650 mm and turning lengths ranging from 1,500 mm to 2,000 mm depending on configuration, making it suitable for industries such as aerospace, oil & gas, and heavy engineering. The main spindle typically reaches speeds up to 4,200 rpm, while the B-axis milling head offers a wide 240° range and a high-speed milling spindle capable of up to 12,000 rpm, enabling full multi-axis machining.
The MULTUS U4000 includes an automatic tool changer with 40 tools (expandable to 80–180 tools), optional sub-spindle, and lower turret for increased productivity. Equipped with Okuma’s OSP-P500 control and advanced automation compatibility, it ensures ease of operation and process integration. Overall, the MULTUS U4000 is designed for manufacturers requiring high flexibility, precision, and reduced setup times in complex machining environments.

WHY BUY USED OKUMA MULTUS U4000
Buying a used Okuma MULTUS U4000 is a strong investment for manufacturers seeking advanced multi-tasking capability without the high cost of a new machine. These machines are engineered for durability, high precision, and long-term performance, making them reliable even after extended use in demanding production environments.
A key factor when evaluating a used MULTUS U4000 is cutting time (spindle hours). 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 applications if properly maintained. Machines exceeding 18,000–25,000 hours may require servicing of critical components such as the B-axis head, milling spindle, or drive systems, but they can still provide strong value for less complex operations.
One of the biggest advantages of the MULTUS U4000 is its ability to consolidate multiple machining processes into a single setup. Even older units retain advanced features such as B-axis milling, Y-axis movement, optional sub-spindle, and dual turret configurations, allowing full part completion without additional machines. This reduces setup time, labor costs, and work-in-progress inventory.
Additionally, Okuma’s strong reputation for thermal stability and machine longevity reduces the risk typically associated with used equipment, making it a reliable long-term investment.
HOW MUCH DOES A USED OKUMA MULTUS U4000COST?
The cost of a used Okuma MULTUS U4000 varies depending on manufacturing year, configuration, condition, and especially cutting time. Since this model has been available since the 2010s, pricing is generally segmented by age and usage rather than pre-2000 categories.
For early-generation machines (2010–2014), prices typically range from $150,000 to $250,000. These machines often have higher cutting hours (12,000–25,000+) and may require refurbishment, but they still offer full multi-tasking capability for complex and large components.
Machines built between 2015 and 2020 generally fall in the $250,000 to $400,000 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 2020 to 2025, prices can range from $400,000 to $700,000 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 is one of the most critical pricing factors—machines with lower spindle hours command significantly higher values regardless of age. Buyers should also evaluate tooling, automation integration, and maintenance history to determine the true overall investment and long-term return.
