The Mazak INTEGREX i-350H ST is a high-capacity, high-productivity multi-tasking CNC machine designed for complete part processing in a single setup. Built on a horizontal platform, it combines turning and full 5-axis milling with a dual-spindle and lower turret configuration, enabling simultaneous machining with multiple tools. This significantly reduces cycle times and improves throughput, making it ideal for complex and high-volume production.
The i-350H ST features a 10-inch chuck, a maximum machining diameter of approximately 670 mm, and a machining length of around 1,500 mm, positioning it for medium-to-large component manufacturing. A long Y-axis stroke and B-axis milling spindle allow for complex contouring, angled drilling, and multi-surface machining without repositioning. Advanced technologies such as MAZATROL SmoothAi control, thermal compensation systems, and high-rigidity construction ensure consistent accuracy during long cutting cycles.
The addition of a lower turret allows parallel operations alongside the milling spindle, improving efficiency and reducing idle time. Commonly used in aerospace, oil & gas, and heavy equipment industries, the i-350H ST is designed for manufacturers seeking maximum productivity, reduced setups, and high precision in demanding machining environments.

WHY BUY USED MAZAK INTEGREX I-350H ST
Purchasing a used Mazak INTEGREX i-350H ST is a strategic decision for manufacturers looking to achieve high productivity without the cost of a new machine. The ST configuration offers a major advantage with its dual-spindle and lower turret setup, allowing simultaneous machining operations that significantly reduce cycle times compared to single-channel machines. This makes it especially valuable for production environments where efficiency and throughput are critical.
Mazak machines are known for their durability, and even used units can deliver reliable performance when properly maintained. Models from 2010 to 2025 typically include advanced MAZATROL Smooth or SmoothAi controls, better automation integration, and improved thermal stability. Machines from 2000–2010, while older, still provide strong mechanical performance and are well-suited for heavy-duty machining applications. Pre-2000 machines in this configuration are rare, but earlier INTEGREX platforms may still be used for less demanding work.
Cutting time is one of the most important evaluation criteria. Machines with lower spindle hours generally have less wear on critical components such as the B-axis milling head, spindles, and turret systems. Maintenance records, tooling packages, and automation readiness also significantly impact value. Overall, buying used allows companies to expand capacity while maintaining cost efficiency and operational flexibility.
HOW MUCH DOES A USED MAZAK INTEGREX I-350H STCOST?
The price of a used Mazak INTEGREX i-350H ST varies based on year, condition, configuration, and total cutting hours. Machines manufactured between 2010 and 2025 typically range from $400,000 to $800,000 or more, reflecting their advanced dual-channel capability, automation features, and modern control systems. Units with low cutting hours and complete maintenance histories often command premium pricing due to their longer remaining service life and reliability.
Machines from the 2000–2010 period are generally priced between $200,000 and $400,000. These models still offer 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 needing high productivity without the investment required for newer machines.
Pre-2000 machines in the i-350H ST configuration are extremely rare, but comparable older INTEGREX models may be available below $180,000 depending on condition and refurbishment. Cutting time plays a crucial role in valuation; machines with high spindle usage may require maintenance or rebuilding, reducing their value. Buyers should also consider included tooling, automation systems, and service history, as these factors significantly influence total investment and long-term performance.
