DOOSAN PUMA 3100XL CNC LATHE

Technical Description

This CNC turning center is engineered for high-volume production of medium to large-diameter cylindrical components with a maximum turning diameter of 20.7 inches and swing capacity of 33.5 inches. The machine accommodates bar stock up to 4 inches in diameter, making it suitable for automotive, aerospace, and industrial applications requiring precision shaft and bushing production. The two-axis configuration (X and Z) provides essential longitudinal and radial positioning for turning, boring, and facing operations with repeatable accuracy across extended production runs. Operating at a maximum spindle speed of 2,800 RPM, this machine prioritizes torque delivery and cutting stability over high-speed finishing, enabling aggressive material removal rates on tough alloys and large-diameter workpieces. The substantial 83.7-inch machining length facilitates production of extended components in single setups, minimizing secondary operations and reducing handling time. The CNC control system automates tool indexing, spindle speed adjustment, and feed rate optimization, ensuring consistent part geometry and surface finish throughout extended production cycles. Rigidly constructed with box-way guideways and integral spindle bearings, the machine resists deflection during heavy interrupted cuts typical of bar stock machining. The 4-inch bar capacity combined with extended machining length enables efficient scrap minimization and maximizes material utilization on longer components. This machine represents an economical solution for job shops and contract manufacturers requiring reliable production of medium to large cylindrical parts without the complexity and cost of multi-axis turning centers with live tooling.
