DOOSAN LYNX 220LMA CNC LATHE

Technical Description

This CNC lathe features a 6.5-inch chuck size and supports a maximum bar capacity of 2.0 inches, powered by a 20 HP spindle motor capable of reaching speeds up to 6,000 RPM. The machine accommodates a maximum turning diameter of 9.84 inches and a turning length of 20.1 inches, with a swing over carriage of 11.4 inches and swing over bed of 20.1 inches. The X and Z-axis travels measure 17.7 inches and 13.0 inches, respectively, allowing precise tool positioning enhanced by a 0.001-degree C-axis indexing accuracy. Rapid traverse rates are high, at 1181 IPM on the X-axis and 1417 IPM on the Z-axis, enabling efficient material removal and reduced cycle times. The spindle bore diameter is 2.4 inches with an A2-6 spindle nose, supporting robust workholding. A powerful 5 HP live tooling motor offers additional machining flexibility with speeds up to 6,000 RPM, driving various tooling setups from the 24-station turret, which indexes rapidly in 0.15 seconds to maximize productivity. The tailstock includes a 3.93-inch diameter quill with a 4.72-inch stroke, featuring an MT-4 taper for stable support of long workpieces. Operating on a 68 Amp power supply, the machine measures 105 x 65 x 65 inches (LxWxH) and weighs approximately 8,820 lbs, balancing footprint and rigidity. Control is maintained via a Fanuc i series CNC system with a color LCD interface, delivering precise numeric control over complex turning tasks, tool management, and repeatability suited for demanding production environments.
