USED OKUMA MA-650V

The OKUMA MA-650V is a large-capacity vertical machining center designed for heavy-duty cutting, high rigidity, and versatile production machining. It is part of Okuma’s MA-V series, which combines the strength of box guideways with the speed advantages of linear guide systems. This hybrid construction allows the machine to perform both aggressive roughing and high-speed finishing on a single platform, making it highly suitable for aerospace, automotive, die & mold, and general heavy engineering applications.

A key feature of the MA-650V is its dual-way guide system, where box ways provide excellent damping and rigidity for heavy cutting, while linear guides enable fast and efficient high-speed movement. This balance allows the machine to maintain stability even under demanding machining conditions. The machine is also equipped with a geared headstock that delivers high torque across the full spindle range, making it effective for both tough material removal and precision finishing.

The machine offers a large working envelope of approximately X: 1,530 mm, Y: 660 mm, and Z: 610 mm, making it suitable for larger components and fixtures. The table size of 1,530 × 660 mm provides strong support for heavy workpieces, improving stability during machining.

The spindle system typically operates at 6,000 RPM as standard, with optional configurations of 12,000 or even 25,000 RPM depending on production requirements. Spindle power options go up to around 22 kW, providing strong torque for roughing while still supporting finishing operations.

Tool capacity is generally 32 tools as standard, with optional upgrades to 48 tools depending on production needs. Rapid traverse rates are very high (around 40 m/min on X and Y axes), helping reduce non-cutting time and improving overall productivity.

Overall, the MA-650V is built as a heavy-duty yet flexible machining center capable of handling large parts with strong cutting performance and stable long-term accuracy.

WHY BUY USED OKUMA MA-650V

Buying a used OKUMA MA-650V is a practical decision for manufacturers who need a large, rigid machining center but want to reduce upfront capital investment. Since this machine is designed for both heavy cutting and high-speed operations, it remains highly valuable even in the used equipment market.

One of the biggest advantages is cost efficiency. A new MA-650V with box/linear hybrid ways, high torque spindle, and large table capacity can be expensive. A used machine allows manufacturers to access similar heavy-duty machining capability at a significantly lower price, making it easier to expand production capacity without major financial strain.

Another key advantage is versatility. The MA-650V is designed to handle both rough machining and finishing on a single machine. This reduces the need for multiple setups or additional machines, improving workflow efficiency and reducing production time. It is especially useful in job shops and production environments handling varied part sizes and materials.

Cutting time (machine hours) is a critical factor when evaluating used machines. Lower-hour machines generally have better spindle condition, less wear on guideways, and higher geometric accuracy. However, due to its box-way structure and internal cooling system, the MA-650V tends to maintain rigidity and performance even at higher hours if properly maintained.

Another advantage is durability. The combination of box ways for rigidity and linear guides for speed makes the machine more robust than standard VMCs in heavy cutting environments. This structural strength ensures stable long-term performance under demanding workloads.

Additionally, Okuma machines benefit from strong global service support and parts availability, which reduces downtime risk and improves long-term reliability for used machine buyers.

Overall, a used MA-650V offers an excellent balance of power, rigidity, and cost savings, making it a strong investment for mixed-production machining environments.

HOW MUCH DOES A USED OKUMA MA-650V COST?

The cost of a used OKUMA MA-650V depends on machine age, condition, spindle configuration, tooling options, and total cutting time. As a large hybrid 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 $70,000 to $160,000. These machines are often 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 $160,000 to $320,000, 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 when properly maintained.

For newer machines manufactured between 2010 and 2025, pricing generally ranges from $320,000 to $600,000+. Units with moderate cutting time (10,000–25,000 hours) usually fall in the mid-range, while low-hour machines with strong maintenance records and optional features such as higher spindle speeds, probing systems, or automation integration command premium pricing.

Cutting time is one of the most important pricing factors. Lower-hour machines typically 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 repairs over time.

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

In conclusion, the used MA-650V market is driven primarily by condition and cutting hours. A well-maintained mid-hour machine typically offers the best long-term value, balancing strong machining capability with reduced investment compared to new equipment.
