FANUC Robodrill α-D21LiB5ADV Plus Y500

The FANUC Robodrill α-D21LiB5ADV Plus Y500 puts the FANUC Series 31i-B5 Plus control, which the table describes as 5-axis capable, on a machine with 700 x 500 x 400 mm (27.6 x 19.7 x 15.7 in) of travel and 21 tools.

Read the axis row carefully. It says the control is 5-axis capable; the travels FANUC lists are the three linear ones, and no rotary axis figures appear in the table. A tilting rotary unit, its size and its weight are therefore things to settle in the quotation, and that weight counts against the 300 kg (660 lb) table load along with the fixture and the part.

The envelope helps here. A rotary unit stands tall on the table, and 400 mm (15.7 in) of Z leaves more room above it than the 330 mm (13 in) of the Robodrill α-D21LiB, while 500 mm (19.7 in) of Y gives more freedom in where the unit sits. Multi-face work also multiplies the tool list, which is the argument for 21 tools over the 14 tools of the Robodrill α-D14LiB5ADV.

The standard spindle turns 10,000 rpm, with a 12,000 rpm tapping / high-acceleration spindle and a 24,000 rpm high-speed spindle as options. The Robodrill α-D14LiB5ADV trades seven tools for a 500 kg (1,100 lb) table load on the same travels and control.
