DOOSAN LYNX 220LSYC CNC LATHES

Technical Description

This Heavy Duty CNC Turn-Mill Center is a precision slant bed machine designed for advanced multi-axis machining operations. With a swing over bed of 23.6 inches and maximum turning diameter of 11.8 inches, it accommodates substantial workpieces up to 20.1 inches in length. The 8-inch chuck and 2.6-inch bar working diameter enable efficient production machining with feed bar capability. The machine features sophisticated multi-axis control with X, Z, and Y-axis travels of 8.1, 22, and 4.1 inches respectively, complemented by dual C-axis indexing (C1, C2) offering 360-degree rotation at 0.001-inch precision. Rapid traverse rates reach 1181.1 IPM on the X-axis and 1417.3 IPM on the Z-axis, ensuring minimal non-cutting time. The main spindle delivers 4500 RPM maximum with A2-6 nose configuration and 3.0-inch through-hole capacity, while the sub spindle operates independently at 6000 RPM with 1.7-inch through-hole diameter. A 12-station turret with 0.11-second indexing time enables rapid tool changes with OD tool capacity of 0.8 x 0.8 inches and maximum boring bar sizes of 1.3/0.8 inches. Motor specifications include 20.1 HP main spindle (30-minute rating), 7.4 HP sub spindle, and 5.0 HP rotary tool drive, demanding 27.8-33.7 KVA electrical supply. Measuring 75.6 inches high, 67.3 inches wide, and 113.4 inches deep with a weight of 8818.4 pounds, this machine integrates submerged chip conveyor systems and flooded coolant recirculation for enhanced operational efficiency.
