USED OKUMA MILLAC 761V II

The OKUMA MILLAC 761V II is a large-format, heavy-duty vertical machining center designed for high-rigidity machining of medium-to-large workpieces. It belongs to Okuma’s MILLAC V II series, which is engineered for strong structural stability, high torque cutting capability, and consistent long-term accuracy. This model is widely used in industries such as aerospace, automotive tooling, heavy equipment manufacturing, and mold & die production where large components and stable cutting performance are required.

A key feature of the MILLAC 761V II is its ultra-rigid box-way construction on all axes, which provides superior vibration damping and excellent stability during heavy cutting operations. The machine is built with a strong base-column structure and optimized rib reinforcement to resist twisting and chatter under load. This allows it to maintain accuracy even during aggressive machining cycles or extended production runs.

The machine offers a large working envelope of approximately X: 1,540 mm, Y: 760 mm, and Z: 660 mm, making it suitable for large molds, dies, and structural components. The table size is about 1,800 × 720 mm with a high load capacity of around 2,000 kg, allowing heavy workpieces to be securely machined.

The spindle system is designed for torque-heavy performance, typically using a geared headstock with speeds up to 4,000 RPM as standard, with optional higher-speed configurations up to 12,000–15,000 RPM depending on setup. Spindle power is around 18.5 kW, delivering strong cutting capability from low to medium speeds.

The machine is generally equipped with a 36-tool automatic tool changer, enabling efficient multi-operation machining. Rapid traverse rates are approximately 16 m/min on all axes, prioritizing stability and cutting strength over ultra-fast light machining.

Overall, the MILLAC 761V II is a robust, heavy-duty VMC designed for large-part machining where rigidity, torque, and long-term accuracy are more important than pure speed.

WHY BUY USED OKUMA MILLAC 761V II

Buying a used OKUMA MILLAC 761V II is a strong choice for manufacturers that need a large, rigid machining center but want to avoid the high cost of new heavy-duty equipment. Since this machine is built on a box-way structure and designed specifically for heavy cutting applications, it retains strong mechanical integrity even after many years of industrial use.

One of the biggest advantages is cost reduction. A new MILLAC 761V II with its large table capacity, rigid construction, and geared spindle system represents a significant investment. A used machine allows access to the same heavy-duty machining capability at a much lower price, making it attractive for job shops and production facilities looking to expand capacity.

Another key benefit is cutting strength. The box-way design provides excellent damping, which is critical when machining large steel blocks, molds, or structural components. This reduces vibration, improves tool life, and helps maintain surface finish quality even under heavy loads.

Cutting time (machine hours) is an important factor when evaluating used units. Machines with lower hours typically have better spindle health, reduced wear on guideways, and higher accuracy retention. However, the MILLAC 761V II is designed for durability, meaning even higher-hour machines can still perform reliably if maintenance has been properly followed.

Another advantage is stability in long production runs. Unlike high-speed VMCs, this machine is optimized for consistent heavy machining rather than rapid light cutting, making it ideal for industries focused on durability and part size rather than cycle speed.

Additionally, Okuma’s strong global service support ensures long-term availability of parts and technical assistance, which is important for maintaining older heavy-duty machines.

Overall, a used MILLAC 761V II offers excellent value for manufacturers needing rigid, high-torque machining capability at a significantly reduced investment.

HOW MUCH DOES A USED OKUMA MILLAC 761V II COST?

The cost of a used OKUMA MILLAC 761V II depends on machine age, condition, spindle configuration, tooling, 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 rebuilding, guideway scraping, 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 range often have moderate cutting hours (20,000–40,000 hours) and can still deliver reliable performance 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) typically fall in the mid-range, while low-hour machines with strong maintenance records and options such as probing systems, upgraded spindles, or automation compatibility 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 or axis servicing.

Other important factors include spindle type (standard vs high-speed options), control generation (OSP versions), and whether the machine has been used in heavy continuous production or lighter-duty applications.

In conclusion, the used MILLAC 761V II market is primarily driven by condition and cutting hours. A well-maintained mid-hour machine typically offers the best long-term value, balancing strong heavy-duty machining capability with a significantly reduced investment compared to new equipment.
