2023 Doosan 5100B CNC Lathe

Description

The Doosan PUMA 5100B is a heavy-duty CNC horizontal turning center engineered for high-torque machining of large-diameter and long shaft parts. Built for demanding production environments, this machine is well suited for oil & gas, energy, heavy equipment, and general industrial applications where rigidity, power, and accuracy are critical.


The PUMA 5100B offers a maximum turning diameter of 25.6 inches and a maximum turning length of 39.1 inches, providing a strong work envelope for medium-to-large components. A large 21-inch chuck capacity and a generous 10.8-inch spindle bore allow for bar work, pipe machining, and heavy workpieces with confidence. With swing over bed of 34.6 inches, the machine accommodates oversized parts while maintaining stability during aggressive cuts.


At the core is a high-torque spindle delivering up to 60.3 HP (30-minute rating) and 2,980 ft-lb of torque, with a maximum spindle speed of 1,500 RPM. This combination supports powerful roughing as well as controlled finishing across a wide range of materials. The BMT75P 12-station turret provides excellent rigidity and repeatability, supporting boring bars up to 2.4 inches in diameter and reducing deflection during heavy cuts.


The machine is equipped with a robust tailstock featuring 80.7 inches of travel and a live MT #6 quill, making it ideal for long shaft work and high-load applications. Powered by the Doosan Fanuc i Plus / Fanuc 32i CNC control, the PUMA 5100B delivers reliable performance, fast processing, and intuitive operation for production-focused shops.


With its large spindle bore, high horsepower, rigid BMT turret, and proven Fanuc control platform, the Doosan PUMA 5100B is a strong solution for manufacturers seeking a durable, high-capacity CNC lathe capable of handling heavy-duty turning applications with consistency and precision.
