CNC lathes ATL HEAVY evo
The ATL HEAVY evo is designed for more demanding machining operations, where the weight of the workpiece, the length, and the cutting depth require a stiffened structure. The base is sized to support large-section tools, maintaining feed regularity even in the presence of substantial removals.
In this configuration, the capacity increases to 12 meters between centers, 1,200 mm in diameter, and up to 7,000 kg in workpiece weight. The spindle, with power up to 56 kW, allows for continuous medium-heavy machining.
Despite being a more massive machine, the ATL HEAVY evo maintains good accessibility to the adjustment points and steady rests, making it suitable for departments that require operational continuity, robustness, and intuitive machine management.
