USED OKUMA MILLAC 852V II

The OKUMA MILLAC 852V II is a large-capacity, heavy-duty vertical machining center designed for high-rigidity machining of medium-to-large components. It is part of Okuma’s MILLAC V II series, which is built for strong cutting performance, structural stability, and long-term accuracy in demanding industrial environments. This model is widely used in aerospace, automotive tooling, heavy engineering, and large mold manufacturing applications where both size and rigidity are critical.

A key feature of the MILLAC 852V II is its extremely rigid box-way construction on all axes, which provides excellent vibration damping and high stability during heavy cutting. The machine is engineered with a strong base-column structure and optimally placed rib reinforcement to prevent twisting and chatter under load. This allows consistent accuracy even during aggressive machining cycles or long production runs. (okuma.com)

The machine offers a large working envelope of approximately X: 2,050 mm, Y: 850 mm, and Z: 750 mm, making it suitable for large and heavy workpieces. The table size is around 2,200 × 850 mm with a maximum load capacity of approximately 2,500 kg, allowing it to handle large fixtures and structural components efficiently. (turn0search0)

The spindle system is designed for heavy cutting, typically using a geared headstock with speeds up to 4,000 RPM as standard, with optional configurations up to 12,000–15,000 RPM depending on requirements. Spindle power is around 18.5 kW, providing strong torque for roughing operations while still supporting finishing work. (turn0search0)

The machine is generally equipped with a 36-tool automatic tool changer (expandable depending on configuration), allowing efficient multi-operation machining. Rapid traverse rates are around 16 m/min, prioritizing stability and cutting strength over ultra-high-speed movement. (turn0search0)

Overall, the MILLAC 852V II is a heavy-duty VMC designed for large-part machining where rigidity, torque, and long-term accuracy are more important than speed.

WHY BUY USED OKUMA MILLAC 852V II

Buying a used OKUMA MILLAC 852V II is a strong investment option for manufacturers who need a large, rigid machining center but want to significantly reduce capital cost. Since this machine is designed for heavy-duty cutting, it retains structural strength and machining capability even after many years of industrial use.

One of the biggest advantages is cost efficiency. A new MILLAC 852V II is a major capital investment due to its large table size, box-way construction, and high-torque spindle system. A used machine allows manufacturers to access the same heavy machining capability at a much lower upfront cost, improving return on investment.

Another major benefit is cutting performance. The box-way design provides excellent damping and rigidity, making it ideal for machining large steel components, molds, and heavy structural parts. This reduces vibration, improves tool life, and ensures stable surface finish quality even under high cutting loads.

Cutting time (machine hours) plays an important role when evaluating used machines. Lower-hour units typically have better spindle condition, less wear on guideways, and higher geometric accuracy. However, even higher-hour MILLAC 852V II machines can remain productive due to their robust construction and heavy-duty design, provided they have been properly maintained.

Another advantage is versatility in production. The machine supports both roughing and finishing operations on large parts, reducing the need for multiple setups and improving workflow efficiency in job shops and production environments.

Additionally, Okuma’s strong global support network ensures long-term availability of spare parts and service, which is important for large-format machines operating in continuous production.

Overall, a used MILLAC 852V II offers a strong balance of rigidity, capacity, and cost savings, making it a reliable choice for heavy machining applications.

HOW MUCH DOES A USED OKUMA MILLAC 852V II COST?

The cost of a used OKUMA MILLAC 852V II depends on machine age, condition, spindle configuration, tooling options, and total cutting time. As a large box-way vertical machining center, pricing is strongly influenced by structural condition and maintenance history.

For older machines (typically pre-2000 or heavily used units with 40,000–70,000+ cutting hours), prices generally range from $60,000 to $140,000. These machines are usually sold in as-is condition and may require spindle refurbishment, guideway reconditioning, or control upgrades before full production use.

For machines built between 2000 and 2010, used pricing typically falls between $140,000 and $280,000, depending on condition and usage 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 $280,000 to $550,000+. Units with moderate cutting time (10,000–25,000 hours) typically fall in the mid-range, while low-hour machines with strong maintenance records and optional features such as upgraded spindles, probing systems, or automation integration command premium pricing.

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

Other key factors include spindle torque configuration, control generation (OSP versions), and whether the machine has been used in heavy continuous production or lighter-duty applications.

In conclusion, the used MILLAC 852V II market is driven primarily by condition and cutting hours. A well-maintained mid-hour machine typically offers the best value, balancing strong heavy-duty machining capability with a significantly reduced investment compared to new equipment.
