Technical Description
The Fanuc 31iB CNC Control powers a high-performance multi-spindle, multi-turret turning center designed for complex, high-precision machining. The machine features a 38-inch distance between centers and a maximum cutting/turning diameter of 20.00 inches, supporting a 10-inch collet chuck with a 3.15-inch spindle bore and a bar capacity of 2.56 inches. The main spindle delivers 35 HP at speeds up to 4,000 RPM with a spindle nose size of 6, while a second spindle provides 15 HP at speeds up to 5,000 RPM, featuring a 2.17-inch bore and spindle nose size of 5. The turret system includes three turrets with a total of 192 tool positions, 12 stations, and 72 live tools across 36 live tool stations, all powered by five geared motors. Turret indexing is completed in 15 seconds, ensuring rapid tool changes and high throughput. The Fanuc 31iB CNC offers advanced digital servo control, supporting up to four simultaneously controllable axes, and integrates features such as linear and circular interpolation, backlash compensation, and precise axis interlock for optimal machining accuracy. The control system also supports multiple part program paths, high-speed auxiliary functions, and advanced motion control algorithms for smooth, efficient operation. Live tooling and milling capabilities are fully integrated, enabling complex milling and turning operations in a single setup. The machine is equipped with nanometer resolution controls, high-speed data transfer, and a user-friendly interface, making it suitable for demanding production environments requiring high accuracy, flexibility, and reliability.
