The Doosan Puma 2100SY is a sub-spindle, Y-axis turn-mill center with the box-way rigidity and Fanuc-controlled dependability that has made the Puma line a staple in high-mix production and precision job shops. This 2012 unit runs an 8-inch hydraulic main chuck on an A2-6 spindle nose, with a 2.99-inch bore and 2.56-inch bar capacity, turning up to 15.98 inches in diameter and 20.47 inches in length behind a 4,500 RPM, 25 HP main spindle. A 6-inch second spindle transfers parts for complete front-and-back machining, while the Y-axis and 5,000 RPM live tooling on the 12-station turret handle off-center milling, drilling, and cross-hole work in the same cycle. It is equipped with an LNS Servo 82 bar feeder, MP Systems 1,000 PSI high-pressure coolant, parts catcher, chip conveyor, and tool presetter, making it a complete, ready-to-run turning cell for aluminum and steel production.
Compared with the Daewoo-era Puma 240MSB it succeeded, the Puma 2100SY is a real step forward: a stiffer 30-degree slant box-way bed, a higher main-spindle speed, an integrated Y-axis for true off-center milling, and a synchronized sub-spindle the older 240 platform could not match for done-in-one throughput. Faster rapids, a servo-indexed BMT turret, and the modern Fanuc control shorten cycle times and simplify multi-face programming. For a shop stepping up from a two-axis lathe or an older Daewoo Puma, this SY-configuration turn-mill folds multiple operations into one setup, delivering more spindle uptime, fewer fixtures, and tighter part-to-part consistency setup after setup.
