OKUMA LU-S1600 HORIZONTAL MACHINING CENTER

Technical Description

The Okuma LU-S1600 is a 4-axis CNC turning center featuring a twin-turret design optimized for precision small-diameter shaft machining. The machine accommodates workpieces up to 6.3 inches in diameter with a maximum turning length of 21.65 inches using an 8-inch chuck capacity. Equipped with a single main spindle rated at 4,000 RPM and 15 horsepower, the lathe delivers 140 N·m of continuous torque for consistent cutting performance. The dual-turret configuration provides twelve tool stations total—six tools on both the upper and lower turrets—enabling simultaneous two-tool cutting operations for enhanced productivity. The X-axis travels 3.93 inches with rapid traverse rates of 65 ipm, while the Z-axis provides 22.44 inches of travel at equivalent rapid speeds, accommodating bar stock up to 2 inches in diameter. The machine utilizes a JIS A2-6 spindle nose with Ø140 flat mounting standard and features both OSP-P300LA and FANUC 0i-TF control options, supporting constant cutting speed control and continuous threading functions. Rapid indexing of 0.15 seconds per tool change minimizes non-cutting time, while the compact footprint makes the LU-S1600 ideal for automotive applications including camshafts, drive shafts, balance shafts, and electrical motor components. The machine's robust spindle design accommodates boring bars up to 1.26 inches diameter for internal machining of complex geometries.
