2017 Fanuc Robodrill D21MiA5 CNC Vertical Machining Center

The Fanuc Robodrill D21MiA5 is a compact, high-speed CNC vertical machining center with a reputation for Fanuc reliability that has made it a fixture in precision drilling, tapping, and milling cells. This 2017 machine features X/Y/Z travels of 19.7" x 15.75" x 12.9", a 24,000 RPM BT30 spindle, and a 21-tool automatic tool changer with chip-to-chip changes around 1.6 seconds for high throughput on small to medium parts. It rides on a 25.6" x 15.7" table rated for 660 lb, moves at rapids up to 54 m/min, and runs the Fanuc 31i CNC control for fast, accurate contouring and rigid tapping. With an 80 mm max tool diameter and 250 mm max tool length, it handles a broad range of tooling in a remarkably small footprint.

Compared to the earlier Fanuc Robodrill T-series machines such as the a-T21iF, this DiA-generation D21MiA5 is a meaningfully faster and stiffer machine. Fanuc upgraded to the 31i control with higher processing speed, raised rapid traverse and acceleration to shorten non-cutting time, and improved structural rigidity and thermal stability for tighter, more repeatable accuracy. The result is more parts per shift and better surface finish than the older Robodrill generation delivered, making this a smart, low-footprint step up for any shop running high-volume drilling, tapping, and light milling at a used-machine price.
