USED OKUMA MU-4000V
The OKUMA MU-4000V is a compact 5-axis multitasking machining center designed for high-precision, complex part machining in a single setup. It belongs to Okuma’s MU-V series, which combines milling and turning capabilities with full 5-axis simultaneous machining. This makes it ideal for aerospace components, medical parts, turbine components, die & mold work, and complex precision engineering applications where accuracy and process integration are critical.
A key feature of the MU-4000V is its trunnion-style rotary table system, which enables simultaneous 5-axis machining along with multi-sided machining in one chucking. The machine uses a highly rigid structure with a direct-drive rotary system that provides strong torque at low speeds and high-speed capability for precision finishing.
The working envelope is approximately X: 740 mm, Y: 460 mm, and Z: 460 mm, making it suitable for small-to-medium precision components with complex geometry. The rotary table is around 400 mm in diameter and supports workpieces up to roughly 300 kg depending on configuration.
The spindle system is designed for both speed and torque. Standard spindle speed is 15,000 RPM, with optional configurations ranging from 12,000 to 25,000 RPM depending on application needs. Spindle power is typically around 22 kW (with higher peak options up to 30 kW), and torque reaches nearly 199 Nm, making it suitable for both aluminum finishing and moderate steel cutting.
Tool capacity starts at 32 tools and can be expanded significantly depending on automation setup, going well beyond 100 tools in high-production configurations. The machine also features high-precision rotary axis control, enabling accurate multi-axis interpolation for complex geometries.
Overall, the MU-4000V is a high-performance 5-axis multitasking machine designed for precision, complexity, and reduced setups in advanced manufacturing environments.

WHY BUY USED OKUMA MU-4000V
Buying a used OKUMA MU-4000V is a strong choice for manufacturers that need a high-end 5-axis multitasking machine but want to avoid the significant capital investment required for a new unit. Since this machine combines milling and turning with full 5-axis capability, it offers high production efficiency even in used condition.
One of the biggest advantages is cost savings. A new MU-4000V can be a major investment due to its advanced trunnion system, high-speed spindle options, and integrated multitasking capability. A used machine allows access to the same complex machining capability at a significantly lower cost, making it attractive for aerospace suppliers, precision shops, and high-value production environments.
Another key benefit is process consolidation. The MU-4000V allows milling, drilling, contouring, and turning operations in a single setup. This reduces part handling, improves accuracy, and significantly shortens total production time. Even used machines retain this advantage, making them highly efficient for complex parts.
Cutting time (machine hours) is important when evaluating used units. Lower-hour machines typically offer better spindle condition, more accurate rotary axis performance, and less wear on critical components. However, because this is a high-end Okuma platform, even higher-hour machines can remain reliable if they have been properly maintained and calibrated.
Another advantage is precision stability. The rigid trunnion design and Okuma’s control systems help maintain accuracy in multi-axis machining, even after long production use. This makes it suitable for both job shops and production environments.
Additionally, Okuma machines benefit from strong service support and long-term parts availability, which reduces risk when purchasing used equipment.
Overall, a used MU-4000V offers an excellent balance of advanced capability, precision, and reduced investment cost.
HOW MUCH DOES A USED OKUMA MU-4000V COST?
The cost of a used OKUMA MU-4000V depends on machine age, condition, spindle configuration, tooling, automation setup, and total cutting time. As a high-end 5-axis multitasking machine, its resale value remains strong in the used market.
For older machines (typically pre-2000 or heavily used units with 40,000–70,000+ cutting hours), prices generally range from $120,000 to $220,000. These machines may require spindle servicing, rotary axis calibration, or control upgrades before full production use.
For machines built between 2000 and 2010, used pricing typically ranges from $220,000 to $350,000, depending on condition and maintenance history. Machines in this range 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 $350,000 to $650,000+. Units with moderate cutting time (10,000–25,000 hours) typically fall in the mid-range, while low-hour machines with advanced options such as turning capability, high-capacity tool magazines, or automation integration command premium pricing.
A major pricing factor is cutting time. Lower-hour machines generally have better spindle life, more accurate rotary axes, and reduced maintenance requirements. Higher-hour machines may be cheaper initially but can require additional investment in spindle rebuilds or 5-axis calibration.
Other important factors include whether the machine has turning capability enabled, tool magazine size, control generation (OSP systems), and automation compatibility such as pallet systems.
In conclusion, the used MU-4000V market is driven mainly by condition and cutting hours. A well-maintained mid-hour machine offers the best value, providing advanced multitasking capability at a significantly reduced cost compared to new equipment.
