USED OKUMA MA-500HII

The Okuma MA-500HII is a mid-to-large size horizontal machining center (HMC) designed to deliver high productivity, precision, and versatility across a wide range of manufacturing applications. Positioned between compact HMCs like the MA-4000H and larger platforms such as the MA-600HIII, the MA-500HII offers an ideal balance of work envelope, spindle performance, and automation capability. It features a 500 mm pallet size and axis travels of approximately 700 mm (X), 900 mm (Y), and 780 mm (Z), allowing it to handle medium to large workpieces efficiently.

The machine is equipped with a range of spindle options, typically starting at 6,000 rpm and extending up to 20,000 rpm depending on configuration. This enables both heavy-duty cutting and high-speed finishing within a single platform. With spindle power around 30/22 kW and rapid traverse rates of approximately 60 m/min, the MA-500HII is built to reduce idle time and maximize cutting efficiency.

A defining feature of the MA-500HII is Okuma’s Thermo-Friendly Concept, which stabilizes machine temperature and maintains consistent accuracy during long machining cycles. This is particularly important in high-production environments where extended cutting time can otherwise lead to thermal distortion. The machine also supports large tool magazine capacities—ranging from 40 up to 400 tools—making it suitable for complex, multi-operation jobs without frequent tool changes.

Designed for both standalone and automated production, the MA-500HII integrates well with pallet changers and flexible manufacturing systems. Its ability to sustain long cutting times with minimal downtime makes it ideal for industries such as automotive, construction equipment, and general machining. Overall, the MA-500HII provides a strong combination of rigidity, speed, and reliability, making it a highly capable solution in the mid-size HMC category.

WHY BUY USED OKUMA MA-500HII

Buying a used Okuma MA-500HII is a practical choice for manufacturers seeking high-performance machining capability at a reduced capital investment. Okuma machines are widely recognized for their robust construction, long operational life, and ability to maintain accuracy over extended periods, which makes them particularly valuable in the used equipment market. Even older MA-500HII units can remain highly productive if they have been properly maintained and serviced.

One of the primary benefits of purchasing used is cost efficiency. A new horizontal machining center in this class requires significant investment, especially when equipped with automation systems and large tool magazines. A used MA-500HII provides access to similar machining capacity—such as large work envelopes, high spindle power, and automation compatibility—at a fraction of the original cost. This allows businesses to allocate capital more effectively while still expanding production capabilities.

Cutting time is a critical factor when evaluating a used machine. Machines with lower spindle hours generally exhibit less wear on key components such as the spindle, guideways, and ball screws. For example, a machine built in the early 2000s with moderate cutting time may offer better long-term reliability than a newer unit that has been heavily used in continuous production. This makes it essential to review maintenance records, spindle load history, and overall machine condition before purchasing.

Another advantage is the availability of upgrades and support. Okuma continues to provide parts and service for older machines, and many MA-500HII units can be retrofitted with updated controls or automation systems. This extends the usable life of the machine and enhances productivity.

Ultimately, buying used enables faster return on investment. With a lower upfront cost and the ability to maintain high cutting time utilization, a used MA-500HII can quickly generate value in both job shop and production environments.

HOW MUCH DOES A USED OKUMA MA-500HII COST?

The cost of a used Okuma MA-500HII varies depending on several key factors, including manufacturing year, machine configuration, condition, and most importantly, cutting time (spindle hours). As a mid-to-large size HMC, it typically falls between the pricing ranges of smaller machines like the MA-4000H and larger systems like the MA-600HIII.

Machines built before 2000 (or early-generation equivalents leading into the MA-500HII platform) generally range from $25,000 to $70,000. These machines are the most affordable but may come with older control systems and higher wear. Cutting time plays a major role here—machines with high spindle hours often require refurbishment, while low-hour units can still be viable for lighter production work.

Models produced between 2000 and 2010 typically range from $70,000 to $140,000. This segment often provides the best value for money, as these machines feature improved controls, better thermal stability, and enhanced machining efficiency. Units with low to moderate cutting time are particularly attractive, as they can deliver strong performance with relatively low maintenance costs.

More recent machines from 2010 to 2025 generally range from $140,000 to $300,000 or more, depending on options such as spindle speed, tool capacity, pallet systems, and automation integration. These machines benefit from advanced control systems, higher spindle speeds (up to 20,000 rpm), and improved reliability for continuous production environments.

Cutting time remains one of the most important pricing criteria. A newer machine with excessive spindle hours may be less valuable than an older machine with minimal use. Buyers should carefully evaluate spindle hours, maintenance history, and component wear to determine the true value and long-term performance potential of a used MA-500HII.
