2017 Fanuc Robodrill D21MiA5 CNC Vertical Mill

The Fanuc Robodrill D21MiA5 is a compact 30-taper CNC vertical machining center known for the speed and reliability that made the Robodrill the world's most popular small machining center. This 2017 unit pairs X/Y/Z travels of 19.69 x 15.74 x 12.9 inches and a 25.6 x 15.74 inch table (660 lb capacity) with a high-power 24,000 RPM spindle on a BT30 Big Plus taper, delivering up to 35 HP for fast high-speed milling, drilling, and tapping. A 21-position turret-style ATC with roughly 1-second tool changes, 2,125 in/min rapids in all axes, and the Fanuc Series 31i-B5 Nano control with ultra-precise 16,000,000 pulse/rev encoders drive precise, high-throughput cycles, while an included Royal Filtermist mist collector keeps the enclosure clean for extended runs.

Compared with the earlier Robodrill T-series it succeeded - machines like the T21iA - the D21MiA5 brought the Fanuc Series 31i-B5 Nano control, ultra-precise 16,000,000 pulse/rev encoders, and AI Contour Control I to the proven 30-taper platform. The DiA5 generation sharpened positioning accuracy, accelerated rigid tapping and rapid traverse, and added smarter thermal-growth compensation over the T-series - upgrades that translate directly into tighter tolerances and shorter cycle times for the shop running it today.
