ATL HEAVY PLUS evo
The ATL HEAVY PLUS evo represents the evolution of the HEAVY model for those who need to work large pieces with greater load capacity and rigidity. The monolithic structure of the bed and the enlarged base improve the dynamic behavior of the machine throughout its entire stroke.
The PLUS configuration brings the turning length to 16 meters and the machinable diameter to 1,600 mm; the load capacity reaches 10,000 kg, supported by a spindle with power up to 71 kW. All these elements make the machine suitable for large components that require long cycles and stable cutting conditions.
Despite its size, the operating areas remain tidy and easily accessible, facilitating set-up and control phases. The ATL HEAVY PLUS evo is suitable for workshops that machine large parts and are looking for a machine capable of sustaining continuous production rates.
