USED MAZAK INTEGREX I‑500ST AG

The Mazak INTEGREX I‑500ST AG is a large‑capacity hybrid multi‑tasking CNC machine that combines precision turning, full 5‑axis milling, and integrated gear cutting into one highly efficient platform. As part of Mazak’s INTEGREX AG series, the “ST” designation means the machine incorporates both a second spindle (“S”) and a lower turret (“T”), allowing simultaneous dual‑spindle and turret machining operations. The “AG” (Auto Gear) package expands the machine’s capability by enabling gear skiving, gear hobbing, and gear milling — allowing complete gear profiles and complex part features to be machined in a single setup without a separate gear cutting center.

Engineered for larger workpieces, the I‑500ST AG typically accommodates part diameters up to roughly 900 mm and extended travel capacities for deep cuts and long features. It features dual high‑torque spindles for simultaneous machining, a powerful B‑axis milling head for multi‑surface contouring, and a rigid hybrid guideway structure to support heavy loads and vibration control during long production cycles. Integrated gear capabilities significantly increase versatility, making the machine suitable for components that require both conventional and precision gear machining.

Equipped with Mazak’s MAZATROL SmoothAi control, the I‑500ST AG offers intuitive conversational programming, advanced diagnostics, and seamless automation integration. Its combination of multi‑process machining and comprehensive gear functionality makes it a strong solution for aerospace, automotive, energy, and heavy industrial manufacturing where precision gear features and consolidated production are mission‑critical.

WHY BUY USED MAZAK INTEGREX I‑500ST AG

Purchasing a used Mazak INTEGREX I‑500ST AG is an effective way to access advanced hybrid multi‑tasking and integrated gear machining capability at a lower capital cost than buying new. The combination of dual spindles, a lower turret, and AG gear‑cutting functions — including skiving, hobbing, and milling — allows complex parts with internal and external gear features to be completed in one setup. This integrated approach reduces handling, minimizes repositioning errors, and improves overall productivity.

Used units produced between 2010 and 2025 typically include MAZATROL Smooth or SmoothAi control systems, which streamline programming, support advanced diagnostics, and enhance automation compatibility. These features help reduce setup time and support integration with pallet changers, robotic loaders, and other automation components. Machines from 2000–2010 may have older control technology and higher spindle hours but still offer robust mechanical performance and multi‑tasking capability. Pre‑2000 machines in this specific AG configuration are rare because integrated gear‑cutting variants represent a more recent advancement in Mazak’s machine lineup.

Cutting time remains one of the most important criteria when evaluating used machines; units with lower spindle, turret, and gear‑machining hours usually show less wear on critical components such as spindles, bearings, rotary axes, and gear heads. Maintenance and service history, tooling packages, and included automation interfaces also significantly influence overall value. Buying used allows manufacturers to expand precision machining capabilities and gear production while managing upfront investment and controlling depreciation.

HOW MUCH DOES A USED MAZAK INTEGREX I‑500ST AG COST?

The price of a used Mazak INTEGREX I‑500ST AG varies widely depending on age, condition, configuration, included gear‑machining capability, and total cutting hours. Machines manufactured between 2010 and 2025 typically range from approximately $550,000 to $1,200,000. Units at the higher end of this range often include low spindle and gear‑machining hours, modern MAZATROL SmoothAi controls, and comprehensive gear‑cutting software packages. Additional options such as automation interfaces, pallet systems, and advanced tooling sets further increase productivity and resale value.

Machines from the 2000–2010 period are generally priced between $300,000 and $700,000, depending on condition, usage, and any retrofits or control upgrades. These older units may have higher accumulated hours and earlier control systems but still provide reliable performance in multi‑process and gear machining applications. Some units may require software or hardware updates to fully support the latest gear machining functions.

Pre‑2000 machines in this exact ST AG configuration are rare, as integrated gear‑cutting versions of the I‑500ST represent more recent developments in Mazak’s hybrid multi‑tasking portfolio. Cutting hours play a major role in valuation; machines with high spindle and gear usage may require upcoming maintenance or component refurbishment, which can lower current market value. Buyers should also consider included tooling, gear software packages, automation readiness, and service history, as these factors significantly impact total investment and long‑term return on ownership.
