2023 Doosan Puma 4100LB CNC Turning Center

The 2023 Doosan Puma 4100LB CNC Turning Center is a heavy-duty horizontal lathe purpose-built for handling large-diameter and extended-length workpieces with exceptional rigidity and precision. Equipped with a formidable 21" hydraulic chuck and a 5.51" spindle bore, the machine is well-suited for oilfield tubing, shaft work, and similar large-scale applications. A 10-position turret manages tooling requirements, offering swift index and robust cutting capabilities across both roughing and finishing cycles. The inclusion of a hydraulic steady rest further reinforces part stability, especially crucial for longer shafts and large hollow workpieces.

The machine dimensions reveal a powerful footprint—approximately 227.4" long x 89.6" wide x 89.5" high, weighing in at 25,133 lbs, a clear testament to its industrial-grade rigidity. These physical characteristics enable the Puma 4100LB to absorb vibration and maintain tolerances under high-load, continuous-duty conditions. Though not all axis travels and feed rates are specified in your input, the Puma 4100LB typically boasts high torque spindle performance with a low-rpm geared spindle designed for superior surface finishes on large parts.
