DOOSAN PUMA 400 CNC LATHES

Technical Description

This 2-axis CNC lathe represents a fundamental yet capable machine tool designed for precision turning and manufacturing operations. The machine features a 15-inch chuck capable of securing bar stock and workpieces of substantial diameter, while its 30 horsepower spindle operating at a maximum of 2,500 RPM provides adequate power for both roughing and finishing operations on medium to large-diameter parts. With a maximum turning diameter of 21.7 inches and a swing capacity of 30.3 inches, this lathe can accommodate sizable cylindrical workpieces while maintaining clearance from machine components. The 42.5-inch machining length enables extended turning operations along the Z-axis, allowing for the production of longer components typical in shaft, bushing, and custom fitting applications. The integrated tailstock provides additional support for longer workpieces during machining, enhancing stability and precision during extended turning operations. Controlled by a FANUC OiTC CNC system, the machine utilizes computer numerical control to determine speed and distance, with stepper motors and servos automating tool positioning along the X and Z axes for superior accuracy and repeatability. This configuration can achieve precision levels as tight as ±0.0005 inches, making it suitable for applications requiring consistent dimensional accuracy across production runs. The 2-axis design is ideal for symmetrical parts and straightforward turning operations, offering a practical balance between capability and operational simplicity for general machining work.
