How much does the FANUC Robodrill α-D28MiB5ADV Plus 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-D28MiB5ADV Plus holds 28 tools, twice the 14 of the Robodrill α-D14MiB5ADV, on the same 500 x 400 x 400 mm (19.7 x 15.7 x 15.7 in) travels and the same 5-axis capable FANUC Series 31i-B5 Plus control.
Tool capacity is the reason to choose it. Machining several faces of a part in one clamping stacks up tools quickly: each face brings its own drills, taps and finishing cutters, and all of them must be loaded before the cycle starts. With 28 positions there is also room to load duplicates of the tools that wear fastest.
The envelope matches the tool count. 400 mm of Z gives height for a rotary unit, its fixture and the part, where the Robodrill α-D14MiB5 on this control has 330 mm (13 in). The table gives linear travels only, so the rotary hardware itself is something to confirm with FANUC. Standard spindle speed is 10,000 rpm; the 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles are optional.

Strengths & Limitations
Strengths
- 28 tools, twice the capacity of the 14-tool Robodrill α-D14MiB5ADV on the same travels and control
- 5-axis capable FANUC Series 31i-B5 Plus control
- 400 mm (15.7 in) of Z travel to go with 500 mm (19.7 in) of X and 400 mm (15.7 in) of Y
- High-speed 24,000 rpm spindle on the options list
Limitations
- The listed figures give no maximum tool diameter, length or weight for the 28 positions
- No rotary axis rows in the table, so the rotary equipment has to be specified and checked separately
- 10,000 rpm is the standard spindle speed; the 12,000 rpm and 24,000 rpm spindles are extras
