The Mazak Mega Turn 900MS is a high-performance vertical CNC turning center designed for large, heavy components that require both turning and milling operations in a single setup. As part of Mazak’s MEGA TURN series, the “MS” variant combines multi-tasking capability with heavy-duty construction, enabling efficient machining of complex parts. The machine features a vertical spindle orientation and a traveling column design, which removes structural limitations and provides a large machining envelope. It offers a maximum machining diameter of approximately 920 mm and a machining height of around 800 mm, making it ideal for large components such as flanges, rings, and industrial castings.
The Mega Turn 900MS is equipped with a high-torque spindle capable of delivering up to 3655 Nm, allowing for aggressive cutting and high material removal rates. A rigid 12-position turret supports both turning and milling tools, enabling process integration and reducing the need for secondary operations. Automation features such as pallet changers and automatic tool changers further enhance productivity and support continuous machining. Overall, the Mega Turn 900MS is widely used in industries such as energy, aerospace, and heavy engineering where precision, power, and efficiency are critical.

WHY BUY USED MAZAK MEGA TURN 900MS
Buying a used Mazak Mega Turn 900MS is a strategic investment for manufacturers needing large-part machining capabilities without the high capital cost of a new machine. One of the biggest advantages is significant cost savings, as machines in this size category are typically expensive when purchased new. Mazak machines are well known for their durability and long service life, making them reliable even after years of operation when properly maintained.
A key benefit of the 900MS model is its ability to combine turning and milling operations in a single setup. This reduces setup time, improves accuracy, and eliminates the need for multiple machines, increasing overall productivity. The vertical design enhances stability and chip evacuation, which is especially important when machining large or unbalanced components.
Used machines are typically available immediately, avoiding long lead times associated with new builds. Many pre-owned units also include additional features such as pallet changers, automation systems, and tooling packages, adding further value. Cutting time is a critical evaluation factor; machines with lower spindle hours generally offer better longevity, reliability, and accuracy. Overall, buying a used Mega Turn 900MS allows manufacturers to expand production capacity while maintaining financial efficiency.
HOW MUCH DOES A USED MAZAK MEGA TURN 900MSCOST?
The cost of a used Mazak Mega Turn 900MS depends on manufacturing year, condition, configuration, and especially cutting time. Machines built before 2000 typically range from $70,000 to $200,000. These older machines often have higher cutting hours and older control systems, but they can still be suitable for less demanding applications or after refurbishment.
Machines produced between 2000 and 2010 generally range from $200,000 to $450,000. These models offer a strong balance between affordability and performance, particularly if they have moderate cutting time and have been well maintained. Many include improved Mazatrol controls and integrated milling capability, making them versatile for complex machining tasks.
More recent machines from 2010 to 2025 typically range from $450,000 to $950,000 or more, depending on configuration, automation features, and overall condition. Machines with low cutting time command premium pricing due to longer remaining service life and higher productivity potential.
Cutting time plays a decisive role in valuation. A newer machine with heavy usage may be less desirable than an older unit with low spindle hours. Buyers should carefully evaluate spindle hours, maintenance history, and included features to determine the true market value of a used Mega Turn 900MS.
