How much does the FANUC Robodrill α-D21LiBADV Plus Y500 cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from FANUC. Configuration moves it a long way.
Overview
The FANUC Robodrill α-D21LiBADV Plus Y500 is the 3-axis, 21-tool machine in FANUC's Y500 group: 700 mm (27.6 in) of X, 500 mm (19.7 in) of Y and 400 mm (15.7 in) of Z, with a 300 kg (660 lb) table load and the FANUC Series 31i-B Plus control.
Three machines share those travels and that control, and tool count is what separates them. The Robodrill α-D14LiBADV carries 14 tools and is rated for 500 kg (1,100 lb) on the table. The Robodrill α-D28LiBADV carries 28 tools at 300 kg (660 lb). This model sits between them with 21 tools, enough for a part with a long operation list plus duplicates of the tools that wear fastest.
Against the standard-envelope Robodrill α-D21LiB, which has 400 mm (15.7 in) of Y and 330 mm (13 in) of Z, the gain is depth and height. A plate that would need two setups to reach across can be machined in one, and taller fixtures fit without giving up tool length.
The spindle is 10,000 rpm as standard, with 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles optional.

Strengths & Limitations
Strengths
- 500 mm (19.7 in) of Y and 400 mm (15.7 in) of Z, against 400 mm (15.7 in) and 330 mm (13 in) on the Robodrill α-D21LiB
- 21 tools, between the 14 tools of the Robodrill α-D14LiBADV and the 28 tools of the Robodrill α-D28LiBADV
- Three spindle choices: 10,000 rpm standard, 12,000 rpm and 24,000 rpm optional
Limitations
- 300 kg (660 lb) table load; the Robodrill α-D14LiBADV on the same travels is rated for 500 kg (1,100 lb)
- Listed as 3-axis; the 5-axis capable Series 31i-B5 Plus control is on the Robodrill α-D21LiB5ADV
- X travel is 700 mm (27.6 in), the same as the smaller-envelope Robodrill α-D21LiB, so long parts gain nothing
