USED OKUMA MCR-BIII
The OKUMA MCR-BIII is a large double-column machining center designed for heavy-duty, high-precision 5-face machining of oversized components in a single setup. It belongs to Okuma’s MCR series, which is widely used in automotive, aerospace, railway, energy, and heavy equipment manufacturing industries where large workpieces, high rigidity, and stable accuracy are essential. The machine is built to handle both rough machining and precision finishing on complex large parts such as dies, molds, and structural components.
A key feature of the MCR-BIII is its rigid ram-type spindle head combined with a strong double-column structure. This design ensures excellent stability during heavy cutting operations and allows multiple machining orientations using interchangeable attachment heads. The system supports 5-face machining in a single setup, significantly reducing repositioning errors and improving production efficiency.
The machine is designed with a wide and scalable work envelope. Depending on configuration, it offers X-axis travel ranging from approximately 3,000 mm up to 12,000 mm, making it suitable for very large components. The distance between columns also varies by model size, typically ranging from about 2,050 mm upward, allowing flexibility for different part dimensions.
The spindle system is built for power and rigidity rather than ultra-high speed. Standard spindle speed is around 4,000 RPM, with optional configurations up to 6,000–10,000 RPM depending on setup. Spindle power is typically around 30/22 kW (or higher configurations up to 40 hp class), enabling strong cutting performance on steel and cast iron.
Tool capacity is also a strong advantage, starting from around 50 tools and expanding up to 180 or more depending on production needs. This supports complex multi-operation machining with reduced downtime for tool changes.
Overall, the MCR-BIII is designed for large-scale industrial machining where rigidity, flexibility through attachments, and long-term dimensional stability are more important than compact size or high-speed light machining.

WHY BUY USED OKUMA MCR-BIII
Buying a used OKUMA MCR-BIII is a practical and cost-effective option for manufacturers that require large-scale machining capability without the extremely high capital investment of a new double-column system. Since this machine is built for heavy structural work, it retains strong rigidity and performance even after many years of industrial use.
One of the biggest advantages is cost reduction. A new MCR-BIII is a major investment due to its large travel capacity, rigid double-column construction, and attachment-based 5-face machining system. A used machine provides access to the same industrial-scale capability at a significantly lower price, making it attractive for heavy engineering, automotive tooling, and mold manufacturing operations.
Another key benefit is 5-face machining efficiency. The machine uses interchangeable attachment heads that allow different machining orientations without full re-fixturing. This reduces setup time, minimizes alignment errors, and improves overall production efficiency. Even in used condition, this flexibility remains highly valuable.
Cutting time (machine hours) is an important evaluation factor. Lower-hour machines generally offer better spindle health, improved guideway accuracy, and reduced wear on mechanical systems. However, due to its heavy-duty structure, the MCR-BIII can still perform reliably at higher hours if maintenance has been properly carried out.
Another advantage is versatility in large-part machining. It can handle everything from heavy roughing to precision finishing of large dies and structural components, making it suitable for both job shops and dedicated production environments.
Additionally, Okuma machines are known for long-term service support and control reliability, which reduces risk when buying used equipment in this category.
Overall, a used MCR-BIII offers excellent value for manufacturers needing large-scale, rigid, and flexible machining capability at a significantly reduced investment.
HOW MUCH DOES A USED OKUMA MCR-BIII COST?
The cost of a used OKUMA MCR-BIII depends heavily on machine size configuration, age, condition, spindle hours, and attachment system setup. As a large double-column machining center, pricing is primarily driven by structural condition and production usage history.
For older machines (typically pre-2000 or heavily used units with 40,000–80,000+ cutting hours), prices generally range from $120,000 to $300,000. These machines are often sold in as-is condition and may require spindle refurbishment, control upgrades, or guideway reconditioning before full production use.
For machines built between 2000 and 2010, used pricing typically falls between $300,000 and $600,000, depending on condition and configuration. Machines in this range often have moderate cutting hours (20,000–50,000 hours) and can still perform reliably in heavy industrial environments if properly maintained.
For newer machines manufactured between 2010 and 2025, pricing generally ranges from $600,000 to $1.2M+, especially for units with extended table travel, high tool capacity, or advanced automation and attachment systems.
Cutting time is one of the most important pricing factors. Lower-hour machines typically have better spindle condition, improved axis accuracy, and reduced wear on attachment changers and guideways. Higher-hour machines may be more affordable initially but can require additional maintenance investment.
Other key pricing factors include table size configuration, spindle power rating, attachment head system condition, tool magazine capacity, and whether the machine has been used in continuous heavy production environments.
In conclusion, the used MCR-BIII market is strongly driven by condition and cutting hours. A well-maintained mid-hour machine typically offers the best balance of cost efficiency and large-part machining capability.
