The Mazak INTEGREX i-450H ST is a high-performance, large-frame multi-tasking CNC machine designed for complete part machining in a single setup. Built on a horizontal platform, it integrates turning and full 5-axis milling with a dual-spindle (S) and lower turret (T) configuration. This allows simultaneous machining using two tools, significantly reducing cycle times and improving productivity.
The machine features a 12-inch main spindle chuck, a maximum machining diameter of approximately 670 mm, and machining lengths up to around 1,500 mm. It is equipped with a powerful milling spindle capable of 12,000 rpm and a wide B-axis range for complex contouring and angled machining. The lower turret supports additional tools, enabling balanced cutting and parallel operations alongside the milling spindle.
Advanced technologies such as MAZATROL SmoothAi control, AI-based thermal compensation, and automation-ready design enhance accuracy and efficiency. The machine is commonly used in aerospace, oil & gas, and heavy equipment industries where large, complex components require high precision. Overall, the i-450H ST delivers maximum productivity by combining multiple machining processes into a single, highly efficient platform.

WHY BUY USED MAZAK INTEGREX I-450H ST
Purchasing a used Mazak INTEGREX i-450H ST is a strategic way to access high-end multi-tasking capability at a significantly reduced cost. The ST configuration provides a major productivity advantage by enabling simultaneous machining through its dual-spindle and lower turret setup. This reduces cycle times, minimizes setups, and improves overall efficiency, especially in high-volume or complex part production.
Mazak machines are engineered for durability, making them reliable even after years of operation. Models from 2010 to 2025 typically include advanced MAZATROL Smooth or SmoothAi controls, improved automation compatibility, and enhanced thermal stability. Machines from 2000–2010, while older, still offer strong mechanical performance and are suitable for heavy-duty machining. Pre-2000 machines in this configuration are extremely rare, though earlier INTEGREX platforms may still be used for less demanding applications.
Cutting time is one of the most critical factors when evaluating a used machine. Lower spindle hours indicate less wear on key components such as the main spindle, sub-spindle, B-axis head, and turret systems. Machines with high cutting hours may require maintenance or refurbishment, impacting overall value. Additionally, service history, tooling packages, and automation readiness significantly influence pricing. Buying used allows manufacturers to expand capacity while maintaining cost efficiency and operational flexibility.
HOW MUCH DOES A USED MAZAK INTEGREX I-450H STCOST?
The price of a used Mazak INTEGREX i-450H ST varies based on year, condition, configuration, and total cutting hours. Machines manufactured between 2010 and 2025 typically range from $450,000 to $950,000 or more, reflecting their advanced dual-channel capability, automation features, and modern control systems. Units with low cutting hours and complete maintenance records often command premium pricing due to their longer remaining service life and reliability.
Machines from the 2000–2010 period are generally priced between $220,000 and $450,000. These models still provide strong multi-tasking performance and large-part capability but may include older control systems and higher usage levels. However, they remain a cost-effective solution for manufacturers seeking high productivity without the investment required for newer machines.
Pre-2000 machines in the i-450H ST configuration are extremely rare, but comparable older INTEGREX machines may be available below $180,000 depending on condition and refurbishment. Cutting hours play a crucial role in valuation; machines with high spindle usage may require rebuilding or component replacement, reducing their value. Buyers should also consider included tooling, automation systems, and service history, as these factors significantly influence total investment and long-term reliability.
