DOOSAN PUMA 4100 XLMC CNC LATHE

Technical Description

This CNC lathe features a 31.1-inch swing over the bed and a 22.0-inch swing over the saddle, accommodating sizable workpieces with a maximum turning diameter of 21.7 inches and a turning length of 120.7 inches. The machine supports a 21-inch chuck size with a workpiece capacity of 4,409 lbs in the chuck and up to 7,936 lbs on the shaft, handling bar stock up to 6.5 inches in diameter through a 7.1-inch spindle bore. Its X-axis travel is 14.3 inches, and Z-axis travel is 122.7 inches, providing comprehensive tool movement along the workpiece. The lathe offers an exceptional C-axis indexing resolution of 0.001 degrees, enabling precise angular positioning, with rapid traverse rates reaching 787 IPM on X and Z axes and 100 IPM on the C-axis. The main spindle delivers up to 1,500 RPM powered by a 50 HP motor, producing 2,432 ft-lbs of torque through an A1-15 spindle nose interface. The 12-station turret accommodates 1" x 1" OD tooling and supports boring bars up to 2.4 inches with a fast 0.25-second turret indexing time. The rotary tool can achieve speeds up to 4,000 RPM. The tailstock features a 4.7-inch diameter quill with the same stroke length, an MT#6 taper, and travels along 120.7 inches to support extended parts machining. Weighing approximately 26,600 lbs with dimensions of 263" x 90" x 90", the machine operates on 380 V, 3-phase, 60 Hz power at 94 AMP and 55 KVA. It is controlled by the FANUC 0i-TF Series CNC, ensuring advanced programmability and precision for complex cylindrical machining applications.
