2-guide CNC lathes ATL MEGALOS evo
The ATL MEGALOS evo is the model in the range dedicated to extra-large components, where mass, diameter, and length require a higher-category platform. The massive structure and high-rigidity base are designed to contain vibrations and deformations even during long cycles.
On this machine, the dimensional range reaches 16 meters between centers and 2,400 mm in diameter, with a load capacity of up to 25,000 kg. The installed spindle can develop up to 105 kW, while the 1,100 mm wide monolithic bench offers generous support for large-volume parts.
Despite its size, the ergonomics are designed to maintain accessibility to the working areas and rationality in the organization of the equipment. ATL MEGALOS evo is a solution suitable for rollers, shafts, cylindrical bodies, and large industrial components.
