MORI SEIKI NT 6600 DCG/6000B CNC LATHE

Technical Description

This heavy-duty CNC lathe is engineered for large-scale cylindrical workpiece machining with exceptional capacity and precision. The 20-inch chuck accommodates bar stock up to 6.40 inches in diameter, while the 42.10-inch maximum swing and turning diameter enable machining of substantial components. The 261-inch distance between centers, combined with a maximum turning length of 239.20 inches and 242.10-inch Z-axis travel, facilitates production of extended shaft assemblies, bushings, and similar elongated parts. The X-axis travel of 40.90 inches provides ample radial tool movement for complex turning and facing operations. Powered by a robust 40 HP spindle motor operating up to 8,000 RPM, this machine delivers sufficient torque and horsepower for aggressive material removal on castings, forgings, and large-diameter steel workpieces. The Fanuc FS-31iA5 CNC control system ensures precise computer-controlled automation, eliminating manual operation while maintaining repeatability and consistency across production runs. This configuration achieves CNC-standard precision tolerances as tight as ±0.0005 inches, making it suitable for critical applications in aerospace, medical, and automotive manufacturing. The machine's multi-axis capabilities allow simultaneous control of workpiece rotation and tool positioning, enabling complex geometries and minimizing repositioning requirements. Ideal for job shops and manufacturers producing medium-to-high-volume runs of intricate turned components, this lathe combines heavy capacity with precision control technology.
