The FANUC ROBODRILL α-D21SiB5 is a compact vertical machining center engineered for high-precision small parts production. Featuring a 630 x 330mm table with 200kg maximum load capacity, it delivers 300 x 300(+100) x 400mm travel across three axes. The machine is equipped with a BBT-30 spindle capable of 24,000 RPM with 26kW continuous power at maximum speed, providing excellent rigidity for both milling and drilling operations. Its advanced 31i-B5 Plus CNC controller enables rapid traverse rates of 54 m/min and programmable cutting feeds up to 30,000 mm/min. The ultrafast 0.7-second tool change system with 21-tool storage capacity significantly reduces cycle times for high-volume production. Exceptional accuracy is maintained with bidirectional positioning repeatability of ±0.004mm per ISO standards. The machine supports advanced features including 5-axis capability through optional hardware integration, synchronized servo motor control for non-backlash machining, and integrated diagnostics with predictive maintenance functionality. Its compact footprint makes it ideal for tooling, medical device, and precision component manufacturing where space efficiency and production throughput are critical. The machine accommodates multiple workpiece clamping configurations and offers optional accessories including rotary/tilting tables and various spindle variants for specialized applications requiring high-speed or high-torque operations.
