The OKUMA GENOS L3000-E is a precision CNC turning center designed for complex multitasking operations in demanding industrial environments. This machine features dual main spindles, each with a maximum turning diameter of 13.39 inches and turning length of 19.69 inches, delivering exceptional productivity for high-volume production. The primary spindle operates at 3,800 RPM with 30 HP, while the secondary main spindle provides 20 HP at identical speed, enabling simultaneous machining operations. An auxiliary sub-spindle operates independently at 6,000 RPM with 10 HP for additional flexibility. The machine accommodates a 12-position turret for turning tools and optional rotary tool spindle with 7 HP at 4,500 RPM for milling capabilities. Standard 2-axis configuration (X, Z) expands to 3 axes with optional Y-axis or sub-spindle (W) implementation. Axis travels include 9.25 inches (X), 17.72 inches (Z) standard with optional 41.34-inch Z extension, delivering rapid traverse rates of 82 iPM across all axes. The OSP control system provides intuitive programming and full range absolute positioning without zero-point returns, enhancing operational efficiency. Featuring an integral spindle design with 100mm bearing bore and 62mm through-hole diameter, the L3000-E delivers exceptional rigidity and dimensional stability of approximately 9 micrometers. This compact yet robust design minimizes vibration, ensuring consistent high-quality finishes across diverse turning, threading, drilling, and optional milling applications.
