2019 Doosan Puma SMX-2600ST CNC Lathe w/ Barfeeder

The 2019 Doosan Puma SMX-2600ST CNC Lathe redefines multi-tasking precision with dual spindles, a 240-degree tilting B-axis, and a lower turret for simultaneous turning and milling. Its 25.98-inch maximum turning diameter and 3.187-inch bar capacity accommodate a wide range of part sizes, while the 12000 RPM milling spindle and 4000 RPM main turning spindle deliver the torque and speed demanded by high-precision aerospace and automotive work. Powered by dual 35-horsepower digital AC motors and managed by the Fanuc 31i-B5 5-axis simultaneous control, this machine achieves seamless coordination between axes for contouring, drilling, and rigid tapping on both spindles.

Compared to standard twin-turret lathes, the SMX-2600ST achieves superior flexibility through its servo-driven 80-tool ATC (expandable to 120 tools), orthogonal Y-axis with 11.81-inch travel, and 240-degree swiveling B-axis head. It combines high-performance hydraulic and coolant systems—delivering 145 PSI to the upper spindle and 65 PSI to the lower turret—with thermal growth compensation and P4-class spindle bearings for stability during extended operations. This model offers true simultaneous 5-axis machining capabilities far beyond conventional mill-turn platforms.
