DAEWOO PUMA 400MB CNC LATHES

Technical Description

This is a heavy-duty CNC lathe designed for precision turning operations on cylindrical workpieces with significant material removal requirements. The machine features a 20-inch chuck size, capable of holding bar stock up to 4.6 inches in diameter, making it suitable for medium to large-scale production work. With a maximum turning diameter of 21.7 inches and a swing capacity of 30.3 inches, this lathe can accommodate substantial workpieces while maintaining rigidity during machining operations. The 41.1-inch machining length provides extended capability for longer components, enabling complex multi-featured parts to be produced in a single setup without repositioning. Powered by a robust 50 HP spindle motor, the machine delivers sufficient torque for aggressive cutting operations, particularly beneficial when machining castings, forgings, or drilling large-diameter holes in steel. Operating at a maximum spindle speed of 2,000 RPM, this machine prioritizes power and torque over high-speed finishing, making it ideal for material removal on large-diameter workpieces rather than precision small-part production. The included tailstock provides crucial support for longer workpieces, minimizing deflection and ensuring dimensional accuracy during extended turning operations. Integration with FANUC 18-T CNC controls delivers computer numerical control automation, enabling precise tool path programming and achieving repeatability as tight as ±0.0005 inches. This configuration makes the machine well-suited for job shop environments and medium-volume production of shafts, bushings, flanges, and custom fittings requiring both power and precision.
