2015 Fanuc Robodrill Alpha-D21LiA5 CNC Machining Center

The 2015 Fanuc Robodrill Alpha-D21LiA5 is a compact, high-cycle vertical machining center built on Fanuc's precision Robodrill platform. Powered by an 18.7 HP spindle motor turning at 24,000 RPM through a BT#30 Big Plus taper, this machine is engineered for demanding, tight-tolerance work where surface finish and tool life are non-negotiable. The work envelope spans 27.56" x 15.76" x 13" over a 27.58" x 15.37" table rated to 396 lbs, and the 21-station arm-type ATC achieves tool-to-tool changes in 1.1 seconds. Rapid traverse rates hit 2,127 IPM with cutting feedrates up to 1,182 IPM, supported by the Fanuc 31i-B5 control — one of Fanuc's most capable CNC platforms for high-speed processing and network integration. This machine comes equipped with a Midaco 2-pallet changer system and a Renishaw TS-27R tool measurement probe already installed.

Compared to the earlier Robodrill Alpha-D21iA5, this Alpha-D21LiA5 upgrades to the Fanuc 31i-B5 control over the older 31i-A5 or 0i-MD, bringing meaningfully faster block processing, expanded program memory, and improved Ethernet connectivity for DNC or networked production environments. The "L" in the model name designates the long-travel configuration, and Fanuc introduced refined servo tuning in this generation that reduces cycle time in repetitive high-speed operations. For shops stepping up from an earlier Robodrill or adding a second machine to an existing cell, this unit offers a proven performance upgrade without the learning curve.
