The 2020 Doosan Puma SMX-3100ST CNC Multi-Tasking Turning Center is built for complete part machining in a single setup. Featuring a 12,000 RPM B-axis milling spindle with CAPTO C6 taper, 26-inch turning diameter, and 60.6-inch turning length, it delivers precision across heavy and intricate operations alike. Equipped with C-axis capability, sub spindle, and Y-axis travel of 11.8 inches, this SMX model supports simultaneous 5-axis operations. Its FANUC 31i-B5 control, tool presetter, LNS ChipBlaster high-pressure coolant, and chip conveyor enhance performance and reliability on complex, high-mix production runs. Compared to standard turning centers, the SMX-3100ST’s integrated milling head and dual-spindle configuration eliminate the need for secondary setups. Its 80-station tool magazine, 12-station live turret, and 35-horsepower B-axis spindle deliver precision and productivity far beyond conventional mill-turn platforms—making it ideal for aerospace, medical, and high-precision manufacturing.
