2018 Fanuc Robodrill a-D21MiB5ADV CNC Vertical Machining Center

The Fanuc Robodrill a-D21MiB5 ADV is a compact-footprint CNC vertical machining center with the reliability and high-speed accuracy that have made the Robodrill line a staple in high-volume drilling, tapping, and precision milling operations. This 2018 unit offers X/Y/Z travels of 19.7 x 15.75 x 15.75 inches over a 25.6 x 15.75 inch table rated to 882 lb, driven by a 24,000 RPM BT30 spindle with a 35 HP one-minute rating for aggressive material removal and fine finishing alike. Rapid traverse reaches 2,126 in/min with cutting feeds to 1,181 in/min, while the 21-tool drum-style automatic tool changer delivers 1.3-second cut-to-cut tool changes to keep spindle utilization high. Control is handled by the Fanuc Series 31i-B5, and this particular machine is equipped with a BBT30 dual-contact spindle interface, high-pressure thru-spindle coolant, a Renishaw tool and part probe, and a chip conveyor - a production-ready configuration for shops running high-mix or lights-out work.

As the ADV evolution of the Robodrill a-D21MiB5 platform, this machine is a meaningful step up from the earlier a-D21MiB5 and a-D21MiA5 generations. Where those earlier models ran slower tool-change cycles and earlier-generation Fanuc controls, the ADV introduces the faster, higher-response 31i-B5 control with advanced look-ahead and smoother high-speed contouring, tighter thermal stability, and the quick 1.3-second tool changes older Robodrills could not match. Combined with the 24,000 RPM spindle and rapid 2,126 in/min positioning, the a-D21MiB5 ADV turns the same floor space into more finished parts per shift - giving buyers a current-generation, high-throughput machining cell at used-equipment value.
