DOOSAN PUMA 400XLB CNC LATHES

Technical Description

This is a heavy-duty CNC turning center designed for large-diameter precision machining operations. The machine features a maximum turning diameter of 21.654 inches with a swing capacity of 30.315 inches, accommodating substantial workpieces for complex turning applications. With a bar capacity of 4.606 inches, the turning center can process solid stock material efficiently for high-volume production runs. The extended machining length of 122.598 inches enables the processing of long components in a single setup, minimizing secondary operations and reducing overall production time. The two-axis configuration (X and Z) provides fundamental turning and longitudinal positioning control, making this machine ideal for straightforward turning operations including facing, threading, and taper turning. Operating at a maximum spindle speed of 2,000 RPM, the machine prioritizes torque and cutting force over speed, making it suitable for heavy-duty roughing and finishing cuts on larger diameter workpieces. The lower RPM range combined with substantial chuck capacity ensures reliable performance during aggressive cutting conditions while maintaining dimensional accuracy. The CNC control system enables full automation of tool positioning, spindle speed, and feed rates, allowing for repeatable precision and consistent part quality across production batches. This turning center is particularly well-suited for industries requiring large-diameter part manufacturing, such as heavy equipment, industrial machinery, and large structural components. The combination of extended machining length, significant turning diameter, and robust construction provides an economical solution for shops specializing in mid-to-large-volume production of precision-turned parts.
