Used DAEWOO DOOSAN PUMA 400B CNC LATHE — sold (CNC Turning Centers)

The Doosan PUMA 400B is a heavy-duty CNC Turning Center featuring a robust slant bed design built for high-precision, rigorous machining environments. Engineered for production engineers seeking rigidity and reliability, this machine is equipped with a powerful Fanuc 21i-TB control system, ensuring precise execution of complex turning operations. The machine offers a maximum turning diameter of 551 mm, a generous swing of 700 mm, and a maximum turning length of 1050 mm, making it exceptionally well-suited for handling large-diameter and elongated workpieces. At the core of its heavy-duty performance is a gear-driven spindle powered by a 22 / 26 kW spindle motor, capable of reaching a maximum rotation speed of 2000 RPM. The spindle features an A2-11 spindle nose, a substantial spindle bore of 132 mm, and a bar capacity of 117 mm, allowing for efficient processing of heavy bar stock and large tubular components. Workholding is securely managed by a large 15" chuck, providing the necessary clamping force for demanding cuts. The machine construction utilizes rigid box guideways, ensuring exceptional vibration damping and thermal stability during heavy material removal. Tooling flexibility is delivered via a 10-station turret, accommodating a sufficient array of tools for diverse machining sequences. For shaft-type components and long workpieces, the integrated tailstock with an MT6 taper provides robust external support, minimizing deflection during high-feed operations. Given its generous capacity, rigid box guideways, and powerful gear-driven spindle, the Doosan PUMA 400B is ideally suited for heavy industries such as oil and gas, automotive, aerospace, and general heavy engineering where large, high-torque turning is required. This used unit has been imported, thoroughly inspected, and is available from Corel Machinery in India, with worldwide shipping options to support global manufacturing facilities.
