USED OKUMA MU-8000V

The OKUMA MU-8000V is a large-format 5-axis multitasking vertical machining center designed for high-precision, complex part manufacturing in a single setup. It belongs to Okuma’s MU-V series, which integrates milling and turning functions with full simultaneous 5-axis machining capability. This makes it ideal for aerospace structures, turbine components, heavy die & mold work, and high-value precision engineering where size capacity, rigidity, and accuracy are all critical.

A key feature of the MU-8000V is its highly rigid double-column structure combined with a large trunnion-style rotary table. This design provides excellent stability during heavy cutting while enabling smooth multi-axis motion for complex geometries. The trunnion table is supported on both ends, improving rigidity and reducing deflection during angled machining, which is essential for high-accuracy 5-axis operations.

The machine offers a large working envelope of approximately X: 925 mm, Y: 1,050 mm, and Z: 600 mm, making it suitable for medium-to-large complex components. The table is typically around 800 mm in diameter, supporting large fixtures and heavy workpieces while maintaining stable machining conditions.

The spindle system is designed for flexibility across materials. Standard spindle speed is 10,000 RPM, with optional configurations ranging from 6,000 up to 25,000 RPM depending on application needs. Spindle power is typically around 11 kW (with higher configurations available up to 22 kW), allowing a balance between torque-heavy roughing and high-speed finishing.

Tool capacity starts at 32 tools and can expand significantly up to 200+ tools in automation-heavy configurations, making it suitable for complex multi-operation machining. Rapid traverse rates can reach up to 50 m/min, improving cycle efficiency and reducing non-cutting time.

Overall, the MU-8000V is a flagship 5-axis multitasking machine built for large, complex parts where process reduction, rigidity, and precision are essential.

WHY BUY USED OKUMA MU-8000V

Buying a used OKUMA MU-8000V is a strong option for manufacturers who need advanced 5-axis multitasking capability but want to significantly reduce capital investment. Since this machine combines milling, turning, and full simultaneous 5-axis machining, it remains highly productive even in used condition.

One of the biggest advantages is cost savings. A new MU-8000V with automation systems, extended tool magazines, and high-end spindle options can be very expensive. A used machine provides access to the same trunnion-based 5-axis capability at a much lower cost, making it attractive for aerospace suppliers, precision engineering firms, and job shops handling complex components.

Another key benefit is process consolidation. The MU-8000V allows multiple operations—roughing, finishing, drilling, contouring, and even turning—in a single setup. This reduces handling errors, improves accuracy, and significantly shortens production time. Even used machines retain this capability, making them highly efficient for complex part manufacturing.

Cutting time (machine hours) is an important evaluation factor. Lower-hour machines typically have better spindle condition, improved rotary axis accuracy, and reduced wear on critical components. However, the MU-8000V is built on a rigid double-column structure, which helps maintain stability and machining accuracy even at higher usage levels if properly maintained.

Another advantage is flexibility in production environments. It supports both low-volume high-mix production and higher-volume precision manufacturing depending on tooling and automation setup.

Additionally, Okuma’s strong global service support ensures long-term availability of spare parts, software support, and maintenance assistance, reducing operational risk for used machine buyers.

Overall, a used MU-8000V offers an excellent balance of advanced capability, rigidity, and cost efficiency for high-value machining applications.

HOW MUCH DOES A USED OKUMA MU-8000V COST?

The cost of a used OKUMA MU-8000V depends on machine age, condition, spindle configuration, tooling capacity, automation level, and total cutting time. As a high-end 5-axis multitasking machine, it holds strong resale value in the used CNC market.

For older machines (typically pre-2000 or heavily used units with 40,000–70,000+ cutting hours), prices generally range from $150,000 to $250,000. These machines are usually sold in as-is condition and may require spindle refurbishment, rotary axis recalibration, or control upgrades before production use.

For machines built between 2000 and 2010, used pricing typically falls between $250,000 and $420,000, depending on condition and maintenance history. Machines in this category often have moderate cutting hours (20,000–40,000 hours) and can still perform reliably in production environments if properly maintained.

For newer machines manufactured between 2010 and 2025, pricing generally ranges from $420,000 to $750,000+. Units with moderate cutting time (10,000–25,000 hours) typically fall in the mid-to-high range, while low-hour machines with advanced options such as large tool magazines, turning capability, or automation integration command premium pricing.

Cutting time is one of the most important pricing factors. Lower-hour machines generally have better spindle life, tighter rotary axis accuracy, and reduced maintenance requirements. Higher-hour machines may be cheaper initially but can require additional investment in spindle rebuilding or 5-axis calibration.

Other factors affecting price include spindle RPM configuration (10,000–25,000 RPM), tool magazine size (32 to 200+ tools), control generation (OSP systems), and whether the machine has been used in continuous aerospace or production environments.

In conclusion, the used MU-8000V market is driven primarily by condition and cutting hours. A well-maintained mid-hour machine typically offers the best value, combining advanced multitasking capability with significant cost savings over new equipment.
