The Mazak Integrex e‑420H is a premium multi-tasking CNC machine designed for the heavy-duty, high-precision machining of large and complex parts. As part of Mazak’s e-series Integrex line, this model stands out with its horizontal construction, long bed capacity, and integrated turning and milling spindles — enabling full 5-axis machining in a single setup.
This machine is a true DONE-IN-ONE solution, built to handle operations such as turning, milling, drilling, boring, and threading in one cycle. It significantly reduces setup time, eliminates multiple machines, and enhances part accuracy. The e‑420H is engineered with dual spindles, a B-axis milling head, and long Z-axis travel, making it ideal for applications involving long shaft work, aerospace parts, energy components, and heavy structural elements.
It features Mazak’s SmoothX or SmoothAi CNC control, offering intuitive programming, high-speed calculation, real-time simulation, and advanced error compensation. The machine’s rigid construction and thermal compensation system ensure stable, accurate performance over extended operation periods. With tool magazine capacities of up to 120 tools and optional automatic pallet changers, it can also be highly automated for lights-out production.
The e‑420H combines power, flexibility, and efficiency — making it a strategic investment for manufacturers looking to produce large-scale, high-complexity parts with minimal intervention and maximum throughput.
