MORI SEIKI NT6600DCG/4000CS CNC LATHE

Technical Description

This is a heavy-duty CNC turning and milling center equipped with the Mori Seiki MSX-711III control system, designed for large-scale production machining. The machine features dual 24-inch hydraulic chucks with impressive swing capacity of 42.10 inches over bed, enabling the processing of substantial workpieces up to 42.10 inches in diameter. With an extended Z-travel of 163.40 inches and maximum cutting length of 160.40 inches, this turning center accommodates long shaft components and complex multi-operation parts. The dual-spindle configuration provides independent 60 HP motors operating at 1,000 RPM each, allowing simultaneous machining operations on both spindles with A1-20 spindle noses for robust clamping. The 100-position tool changer with live milling capability up to 8,000 RPM delivers flexible 5-axis contouring for integrated turning and milling operations in a single setup, minimizing secondary operations. Rapid traverse rates of 1,576 and 1,260 IPM ensure efficient positioning between cuts. An 18-inch steadyrest capacity supports long, slender workpieces to prevent deflection during high-precision machining. The MSX-711III control integrates FANUC technology for intuitive CNC programming and operation. High-pressure coolant systems and chip conveyor management optimize tool life and continuous production. This configuration exemplifies modern multi-tasking lathe capabilities, ideal for aerospace, automotive, and precision manufacturing applications requiring complex geometries and tight tolerances in one chucking operation.
