USED OKUMA MB-46V II

The OKUMA MB-46V II is a high-precision vertical machining center designed for stable, efficient, and versatile machining of a wide range of components. It belongs to Okuma’s MB-V series, which is known for combining rigid construction, thermal stability, and high productivity in a compact footprint. The machine is widely used in automotive, aerospace, mold & die, and general engineering applications where accuracy and repeatability are critical.

A key feature of the MB-46V II is its extremely rigid double-column structure, which enhances stability and minimizes vibration during machining. This allows the machine to maintain high accuracy even during long production runs or heavy cutting conditions. The machine also benefits from Okuma’s Thermo-Friendly Concept, which reduces thermal deformation and ensures dimensional stability without requiring strict climate-controlled environments.

The MB-46V II offers a working envelope of approximately 560 mm (X-axis), 460 mm (Y-axis), and 460 mm (Z-axis), making it suitable for medium-sized components. It typically features a table size around 760 x 460 mm and supports workpiece weights up to approximately 500–700 kg depending on configuration.

Spindle options include speeds up to 15,000 RPM (standard), with alternative configurations such as 8,000 RPM high-torque or higher-speed variants depending on application needs. The spindle power ranges up to around 22 kW, allowing a balance between high-speed finishing and moderate heavy cutting. Tool capacity is typically 20 tools standard, with optional magazines up to 32 or 48 tools for higher productivity.

Rapid traverse rates reach approximately 42 m/min on X and Y axes, improving non-cutting time efficiency and overall cycle performance. Combined with Okuma’s OSP control system, the MB-46V II delivers smooth operation, user-friendly programming, and stable machining performance.

Overall, the MB-46V II is a proven, reliable vertical machining center built for precision, efficiency, and long-term production stability.

WHY BUY USED OKUMA MB-46V II

Buying a used OKUMA MB-46V II is a practical choice for manufacturers who want reliable CNC performance without the high capital cost of a new machine. Since this model is part of Okuma’s long-running MB-V series, it has a strong reputation for durability, accuracy, and long service life, making it highly desirable in the used market.

One of the biggest advantages is cost savings. A new MB-46V II offers advanced features like thermal stability control, rigid double-column construction, and high-speed spindle options, but the investment can be significant. A used machine allows access to similar machining capabilities at a much lower price, helping shops expand capacity or replace older equipment economically.

Another key benefit is machining reliability. The MB-46V II is designed for consistent accuracy over long production runs, supported by its Thermo-Friendly Concept, which reduces thermal deformation and improves dimensional stability. This makes it especially valuable in industries where tight tolerances are required.

Cutting time (machine hours) plays an important role when evaluating used units. Machines with lower cutting hours generally have less wear on spindle bearings, guideways, and ball screws, resulting in better accuracy and longer remaining life. However, the MB-46V II is known for its robust construction, meaning even higher-hour machines can remain productive if properly maintained.

Another advantage is flexibility. The machine supports a wide range of materials, from aluminum to harder alloys, making it suitable for both job shops and production environments. Tool magazine options (20 to 48 tools) also allow for multi-operation machining with reduced downtime.

Additionally, Okuma’s global support and strong parts availability make long-term maintenance of used machines more secure compared to many other brands.

Overall, a used MB-46V II offers a strong balance of cost, reliability, and productivity, making it a dependable investment for general machining applications.

HOW MUCH DOES A USED OKUMA MB-46V II COST?

The cost of a used OKUMA MB-46V II depends on machine age, condition, configuration, and total cutting time. Since it is a widely used and well-established vertical machining center, it has a relatively stable pricing range in the used market.

For older machines (typically pre-2000 or very early units with extremely high cutting hours of 40,000–70,000+ hours), prices generally range from $25,000 to $70,000. These machines may require refurbishment such as spindle rebuilding, guideway scraping, or control upgrades, but can still be useful for lower-precision work or secondary operations.

For machines built between 2000 and 2010, used prices typically range from $70,000 to $150,000 depending on condition and usage history. Machines in this category often have moderate cutting hours (20,000–40,000 hours) and can still deliver solid production performance if well maintained.

For newer machines built between 2010 and 2025, prices generally range from $150,000 to $300,000+. Units with moderate cutting hours (10,000–25,000 hours) typically fall in the mid-range, offering a strong balance between cost and remaining service life.

Low-hour machines (under 10,000–15,000 hours), especially those with options like higher-speed spindles, larger tool magazines, or probing systems, can reach the upper end of the range or slightly above due to strong demand and longer expected lifespan.

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

In conclusion, a used MB-46V II is generally considered a high-value purchase in the mid-size VMC category. The best investment is usually a well-maintained, moderate-hour machine that balances affordability with long-term machining reliability.
