FANUC Robodrill α-D14SiBADV Plus

The FANUC Robodrill α-D14SiBADV Plus is a 3-axis vertical machining center with 300 mm (11.8 in) of X travel, 400 mm (15.7 in) of Z, a 14-tool changer and the Series 31i-B Plus control. Y is listed as 300 mm (11.8 in) + 100 mm extension, and the table as 500 x 400 mm (19.7 x 15.7 in).

FANUC's table for this model is clear about the spindle, and the choice matters more than any other line on the order. The standard spindle runs to 10,000 rpm. A high-torque spindle is listed for heavy machining of steel parts, with a maximum of 100 Nm (73.7 ft-lbf). A high-acceleration spindle is listed for high speed and high efficiency machining of aluminum parts. Then come a tapping spindle at 12,000 rpm and a high-speed spindle at 24,000 rpm.

Each of those pulls the machine toward a different kind of shop. The 100 Nm (73.7 ft-lbf) version is the one for steel parts, larger drills and bigger taps. It is an option, so a machine ordered without it should not be judged by that figure. The 24,000 rpm spindle belongs with small end mills and fine finishing. The 12,000 rpm tapping spindle fits parts where threads dominate the cycle.

The 400 mm (15.7 in) Z travel is the other reason to pick this model over the Robodrill α-D14SiB, which lists 330 mm (13 in). Taller fixtures, long drills and stacked workholding all take Z. X remains short at 300 mm (11.8 in), so the extra room is vertical only. For work that needs more than 14 tools, FANUC lists the Robodrill α-D21SiBADV with 21 tools.
