2018 Fanuc Robodrill a-D21MiB5adv CNC Vertical Mill

The Fanuc Robodrill a-D21MiB5adv is a compact 30-taper CNC vertical machining center with the reliability reputation that has made the Robodrill line a staple in high-volume drilling, tapping, and milling operations. This 2018 unit pairs X/Y/Z travels of 19.69 x 15.74 x 15.74 inches and a 25.6 x 15.74 inch table (551 lb capacity) with a high-torque 10,000 RPM spindle on a BT30 Big Plus taper for confident 30-taper cutting. A 21-position turret-style ATC with roughly 0.7-second tool changes, 2,125 in/min rapids in all axes, and the Fanuc Series 31i-B5 Nano control deliver fast, accurate cycle times, while an included Royal Filtermist mist collector and chip system keep the work zone clean for extended unattended running.

Compared with the earlier Robodrill a-D21MiA5 generation it replaces, the a-D21MiB5adv advances the platform in meaningful ways. The MiB5adv increases Z-axis travel from 13 inches to 15.74 inches for taller workpieces and longer tools, extends spindle-nose-to-table clearance, and trims tool-change time for higher throughput, all while keeping the proven 31i-B5 Nano control and rigid BT30 spindle. For the shop running it, that means a newer, more capable machine with greater Z clearance and faster chip-to-chip performance - real production gains over the earlier MiA5 generation.
