The Mazak Integrex i-350ST NEO is a high-performance next-generation multi-tasking CNC machine designed for maximum productivity through process integration and simultaneous machining. As part of Mazak’s i-NEO series, it combines turning, milling, drilling, and secondary operations into a single platform under the “DONE IN ONE” concept, enabling complete part machining in one setup. The “ST” configuration includes a main spindle, a second spindle, and a lower turret, allowing multiple operations to be performed simultaneously and significantly reducing cycle times.
The machine supports full 5-axis simultaneous machining with a B-axis milling spindle and high-precision C-axis control, enabling complex geometries and tight tolerances. It is typically equipped with a 10-inch chuck and offers a maximum machining diameter of approximately 670 mm and a machining length of around 1519 mm, with a Y-axis travel of about 300 mm. These specifications make it suitable for medium to large, high-complexity components.
The milling spindle operates at 12,000 RPM as standard with optional 20,000 RPM configurations, supported by a powerful 24 kW motor for heavy-duty and high-speed machining. Advanced features such as Mazatrol SmoothAi control, AI-based thermal compensation, and automation compatibility ensure consistent accuracy and efficiency. Overall, the Integrex i-350ST NEO is ideal for aerospace, oil & gas, and precision engineering applications.

WHY BUY USED MAZAK INTEGREX I-350ST NEO
Buying a used Mazak Integrex i-350ST NEO is a strategic investment for manufacturers seeking maximum productivity and advanced multi-tasking capability at a reduced capital cost. The ST configuration is one of the most advanced setups in the Integrex lineup, combining dual spindles with a lower turret to enable simultaneous machining. This significantly reduces cycle time and increases throughput compared to standard machines.
Used machines typically offer savings in the range of 20% to 50% compared to new units, depending on condition, configuration, and cutting hours. Cutting time is one of the most critical factors when evaluating a used machine. Units with high cutting hours are more affordable but may require maintenance on key components such as both spindles, the milling head, and the lower turret system. However, due to Mazak’s robust construction and advanced thermal compensation systems, even higher-hour machines can remain productive when properly maintained. Machines with low cutting time command a premium due to reduced wear and longer service life.
Another key advantage is efficiency. The ability to perform multiple operations simultaneously reduces setup time, labor, and handling errors. Additionally, used machines are often available much faster than new ones. Many used units also include tooling packages and automation systems, further improving value and return on investment.
HOW MUCH DOES A USED MAZAK INTEGREX I-350ST NEOCOST?
The cost of a used Mazak Integrex i-350ST NEO varies depending on machine condition, configuration, and especially cutting time. Since this is a newer-generation machine, models before 2000 or even 2000–2010 are not applicable. Most machines available in the used market fall within the 2015–2025 range.
Early-generation NEO or near-NEO equivalent machines from around 2015 to 2018 typically range between $450,000 and $700,000, particularly if they have moderate to high cutting hours. These machines offer full ST configuration benefits, including dual spindles and a lower turret, at a lower entry cost but may require maintenance depending on usage.
More recent machines from 2018 to 2025 generally range from $700,000 to over $1,500,000, depending on configuration, automation features, and cutting hours. Machines with low cutting time command significantly higher prices due to reduced wear and longer operational life. Units equipped with additional features such as automation systems, high-speed spindle options, extended bed lengths, and tooling packages can further increase pricing.
Cutting time remains one of the most critical factors in determining value, as it directly impacts spindle condition, turret wear, and long-term reliability. Overall, the i-350ST NEO maintains strong resale value due to its advanced simultaneous machining capability, modern technology, and high demand in precision manufacturing industries.
