USED OKUMA MILLAC 561V II

The OKUMA MILLAC 561V II is a large-capacity, high-rigidity vertical machining center designed for heavy cutting, stable precision machining, and efficient production of medium-to-large workpieces. It belongs to Okuma’s MILLAC V II series, which is engineered specifically for demanding industrial applications where rigidity, torque, and long-term dimensional stability are critical. This model is widely used in aerospace, automotive tooling, heavy equipment manufacturing, and general engineering sectors.

A key feature of the MILLAC 561V II is its extremely rigid box-way construction on all axes, which provides excellent vibration damping and superior stability during heavy machining. The machine is built on a strong base-column structure with strategically placed ribs to resist twisting and chatter during aggressive cutting operations. This makes it highly suitable for continuous production environments where tool load and cutting forces are high.

The machine offers a generous working envelope of approximately X: 1,050 mm, Y: 560 mm, and Z: 520 mm, allowing it to handle larger components compared to mid-size VMCs. The table size is around 1,350 × 560 mm with a maximum load capacity of about 1,000 kg, making it suitable for heavy fixtures and steel components.

The spindle system is designed for both torque and speed flexibility. Standard configurations include 6,000 RPM and 10,000 RPM options, with spindle power up to approximately 22 kW, allowing strong roughing capability while still supporting finishing operations.

The machine typically comes with a 20-tool automatic tool changer, with optional expansions depending on production requirements. Rapid traverse rates of around 32 m/min in X and Y axes help reduce non-cutting time and improve overall cycle efficiency.

Overall, the MILLAC 561V II is a heavy-duty vertical machining center built for stability, torque-heavy cutting, and consistent long-term accuracy in demanding production environments.

WHY BUY USED OKUMA MILLAC 561V II

Buying a used OKUMA MILLAC 561V II is a strong practical option for manufacturers who need a rigid, heavy-duty vertical machining center but want to reduce capital investment. Since this machine is built on a box-way structure and designed for heavy cutting, it maintains structural integrity and machining capability even after years of industrial use.

One of the biggest advantages is cost savings. A new MILLAC 561V II with its high-torque spindle system, large table capacity, and rigid construction can be expensive. A used machine allows manufacturers to access similar heavy-duty machining performance at a significantly lower investment, improving return on capital while still supporting production needs.

Another key benefit is machining strength. The box-way construction provides superior damping and stability compared to linear-guide machines, making it ideal for heavy cutting applications such as steel blocks, molds, and large structural components. This rigidity ensures stable surface finish and reduced vibration even under high cutting loads.

Cutting time (machine hours) is an important evaluation factor. Machines with lower cutting hours generally have better spindle health, reduced wear on guideways, and higher geometric accuracy. However, the MILLAC 561V II is designed for durability, so even higher-hour machines can remain productive if properly maintained.

Another advantage is versatility in production environments. The machine supports both roughing and finishing operations on a single platform, reducing the need for multiple setups or machines. This improves workflow efficiency in job shops and production facilities.

Additionally, Okuma’s strong global support network ensures availability of spare parts and service, which is especially important for heavy-duty machines operating in continuous production environments.

Overall, a used MILLAC 561V II offers a strong balance of rigidity, torque, and cost efficiency, making it a reliable long-term investment for demanding machining applications.

HOW MUCH DOES A USED OKUMA MILLAC 561V II COST?

The cost of a used OKUMA MILLAC 561V II depends on machine age, condition, spindle configuration, tooling options, and total cutting time. As a large, heavy-duty box-way machining center, pricing is strongly influenced by mechanical condition and production 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 often sold in as-is condition and may require spindle refurbishment, guideway scraping, or control upgrades before full production use.

For machines built between 2000 and 2010, used pricing typically falls between $140,000 to $280,000, depending on condition and maintenance history. Machines in this range often have moderate cutting hours (20,000–40,000 hours) and can still deliver reliable performance in production environments if properly maintained.

For newer machines manufactured between 2010 and 2025, pricing generally ranges from $280,000 to $500,000+. Units with moderate cutting time (10,000–25,000 hours) usually sit in the mid-range, while low-hour machines with strong maintenance records and optional features such as upgraded spindles or probing systems command higher pricing.

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

Other important factors include spindle configuration (speed vs torque setup), tool magazine capacity, and whether the machine has been used in heavy continuous production or lighter job-shop environments.

In conclusion, the used MILLAC 561V II market is driven primarily by condition and cutting hours. A well-maintained mid-hour machine typically offers the best value, delivering strong heavy-cutting capability at a significantly reduced cost compared to new equipment.
