02 September, 2025Zayer, a global leader in high-precision machining solutions, will present its innovative ALTEA W gantry milling machine at the EMO 2025 fair, a machine that redefines the standards of productivity, precision, and versatility in the machining of large components.
The ALTEA W stands out for its mobile bridge design with fixed table and moving cross beam (W axis), which provides an optimal combination of structural rigidity, accessibility, and range of travel. This configuration allows large-volume parts to be machined without compromising stability or precision. Furthermore, its compact and efficient design optimizes plant space compared to machines with a moving table, facilitating access to complex areas of the part through a wide range of automatic heads.
Key Features
- Travels: longitudinal up to 20,000 mm; cross up to 5,000 mm; vertical up to 1,800 mm; and movable crossrail up to 1,500 mm (optional depending on configuration).
- Feed rates: rapid traverse up to 30,000 mm/min and working feed up to 25,000 mm/min.
- Head: 45º/30º versions, indexed every 0.001º or in continuous rotation, with power ranging from 33 kW to 63 kW and speeds between 12,000 and 24,000 rpm.
- Automatic head changer, ensuring maximum adaptability without compromising precision.
Built entirely in cast iron and equipped with prismatic guides and adjustable preload roller packs on the vertical axis, the ALTEA W offers extraordinary thermal and geometric stability over time, ensuring high surface quality even in the most demanding working conditions.
The ALTEA W is available with the most advanced numerical controls on the market, such as Heidenhain TNC7 or Siemens Sinumerik ONE, which provide intuitive interfaces and powerful programming and simulation tools.
Thanks to its robustness, precision and versatility, the ALTEA W is specially designed to respond to the needs of sectors such as aeronautics, power generation and the manufacturing of large mechanical components, where performance and reliability make the difference.”
