Technical Description
The Fanuc 31iB CNC Control powers a high-performance dual-spindle turning center with a 38-inch distance between centers and a maximum cutting/turning diameter of 20.00 inches. The primary spindle features a 2.56-inch bar capacity, an 8.0-inch collet chuck, a 3.15-inch spindle bore, and delivers 35 HP at up to 4,000 RPM, with a spindle nose size of 6. The secondary spindle provides a 6.0-inch chuck, a 2.17-inch bore, 15 HP, and reaches 5,000 RPM, with a spindle nose size of 5, enabling efficient part transfer and backworking. The machine is equipped with a high-capacity turret offering 192 tool positions, indexing each position in just 0.15 seconds, and supports up to 24 live tool stations with a maximum of 48 live tools for complex milling and drilling operations. Live milling tools can achieve speeds up to 6,000 RPM, enhancing versatility for multi-tasking applications. The Fanuc 31iB control delivers advanced digital servo management for up to four simultaneously controllable axes, supporting high-speed, high-accuracy machining with features such as linear and circular interpolation, helical interpolation, and precise positioning. The control system integrates robust programming and operational functions, including DNC operation, MDI, program search, dry run, single block, manual feed, reference point return, and comprehensive error compensation. With its combination of powerful spindles, rapid turret indexing, extensive live tooling, and the advanced Fanuc 31iB CNC, this machine is engineered for high-productivity, precision turning and milling in demanding production environments.
