FANUC Robodrill α-D28MiBADV Plus

The FANUC Robodrill α-D28MiBADV Plus is a 3-axis compact machining center defined by its tool capacity: 28 tools, on travels of 500 mm (19.7 in) in X and 400 mm (15.7 in) in both Y and Z, under the FANUC Series 31i-B Plus control.

For 3-axis production, 28 tools is less about any single part than about the mix of parts. A machine that runs several part numbers in rotation can keep every job's tools loaded and move from one to the next by calling a different program, with no tool setting in between. The Robodrill α-D14MiBADV has identical travels and the same control with half the capacity, 14 tools. The Robodrill α-D21MiB holds 21 and has 330 mm (13 in) of Z.

The 400 mm Z stroke supports that kind of mixed running, because the tallest fixture in the rotation sets the height every job has to live with. One check is worth making with a load this large: the listed figures give no maximum tool diameter, length or weight, so get those limits before planning big cutters next to each other. The standard spindle is 10,000 rpm, and FANUC lists 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles as options.
