USED MAZAK INTEGREX I‑450H ST AG

The Mazak INTEGREX I‑450H ST AG is a heavy‑duty hybrid multi‑tasking CNC machine engineered to integrate precision turning, full 5‑axis milling, and advanced gear‑cutting capabilities into one highly versatile platform. Building on the robust I‑450H base, the ST variant includes both a second spindle (“S”) and a lower turret (“T”), enabling simultaneous dual‑spindle and turret operations. The “AG” designation (Auto Gear) adds comprehensive gear machining functions — such as gear skiving, gear hobbing, and gear milling — allowing complete gear production alongside complex part machining without the need for separate gear machines.

Designed for large and demanding workpieces, the I‑450H ST AG typically accommodates diameters well over 800 mm with extended travel capacities. This makes it ideal for aerospace, automotive transmission systems, energy, and heavy industrial applications. It features dual spindles for simultaneous part handling, a powerful B‑axis milling head capable of dynamic contouring, and a rigid hybrid roller guide structure that enhances stability during heavy cutting and long production cycles. Integrated gear capabilities expand the machine’s utility by enabling complex gear profiles to be machined directly on the multi‑tasking platform.

Mazak’s MAZATROL SmoothAi control system provides intuitive conversational programming, advanced diagnostics, and seamless automation integration. The I‑450H ST AG is engineered to reduce setup times, increase throughput, and consolidate multiple machining processes — including gear production — in one efficient production cell.

WHY BUY USED MAZAK INTEGREX I‑450H ST AG

Purchasing a used Mazak INTEGREX I‑450H ST AG is a strong choice for manufacturers looking to expand their machining capabilities without the high cost of a new machine. This model’s combination of dual spindles, lower turret, and integrated gear cutting allows entire parts — including precision gear features — to be completed in a single setup. This dramatically reduces non‑productive time, improves part accuracy, and enhances overall throughput, which is critical for competitive production environments such as automotive, aerospace, and heavy equipment manufacturing.

Used machines from 2010 to 2025 typically feature MAZATROL Smooth or SmoothAi controls, offering improved programming efficiency, advanced diagnostic tools, and better integration with automation systems. These characteristics support high mix‑low volume production as well as larger batch runs. Machines from 2000–2010, while equipped with older controls and potentially higher usage levels, still often provide strong structural performance and multi‑tasking capability. Pre‑2000 machines in this exact ST AG configuration are uncommon, as integrated gear‑cutting AG technology represents a more recent advancement in Mazak’s lineup.

Cutting time remains one of the most important criteria when evaluating a used unit; machines with lower spindle, turret, and gear‑machining hours typically exhibit less wear on key components such as spindles, bearings, rotary axes, and gear heads. Maintenance history, tooling packages, automation interfaces, and included gear software also significantly impact value. Buying used allows manufacturers to gain advanced multi‑process and gear‑integrated capability while managing upfront capital costs and minimizing depreciation compared with purchasing new.

HOW MUCH DOES A USED MAZAK INTEGREX I‑450H ST AG COST?

The cost of a used Mazak INTEGREX I‑450H ST AG depends on several key factors, including age, overall condition, configuration, included gear‑machining capability, and total cutting hours. Machines manufactured between 2010 and 2025 typically range from approximately $500,000 to $1,000,000. Units toward the higher end of this range generally have low spindle, turret, and gear hours, modern MAZATROL SmoothAi control systems, and additional options such as automation interfaces or advanced tooling packages that enhance productivity and long‑term value.

Machines from the 2000–2010 period are generally priced between $300,000 and $650,000, depending on condition, usage, and any upgrades. These older units may feature earlier control technology and higher accumulated hours, but still provide robust multi‑tasking and gear machining performance. Some machines may benefit from control or software upgrades to fully support today’s gear‑machining demands, which should be factored into cost assessments.

Pre‑2000 machines in this exact ST AG configuration are rare, as integrated gear‑cutting INTEGREX AG platforms represent a newer generation of technology. Cutting hours are a major valuation factor; machines with high usage in both spindle and gear axes may require refurbishments or component replacement, which can lower their market price. Buyers should also consider included tooling, gear software packages, automation readiness, and documented maintenance history, as these elements significantly influence total investment and long‑term return on ownership.
