How much does the FANUC Robodrill α-D14MiB5ADV 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-D14MiB5ADV Plus puts 400 mm (15.7 in) of Z travel under a 5-axis capable control, the FANUC Series 31i-B5 Plus. X travel is 500 mm (19.7 in) and Y is 400 mm (15.7 in), so the machine is as tall in Z as it is deep in Y, and it holds 14 tools.
Height is the point of this variant. The Robodrill α-D14MiB5 has the same control, X, Y and tool count with 330 mm (13 in) of Z, which makes the 400 mm stroke here about 21% longer. Where the control is expected to drive a rotary axis, that extra stroke gives a rotary fixture, the part and a longer tool more room to fit under the spindle together.
Tool capacity is the figure that did not grow. Fourteen tools go quickly when a part is machined on several faces, since each face tends to need its own drills, taps and chamfer tools. The Robodrill α-D21MiB5 offers 21 tools on this control, with the 330 mm Z.
As listed, the standard spindle turns 10,000 rpm, and the 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles are options. The table gives no rotary axis figures, so confirm which rotary unit, if any, comes with the machine.

Strengths & Limitations
Strengths
- 400 mm (15.7 in) of Z, against 330 mm (13 in) on the Robodrill α-D14MiB5 with the same control
- 5-axis capable FANUC Series 31i-B5 Plus control
- Z stroke equal to the 400 mm (15.7 in) Y stroke, which helps with tall fixtures on a machine with 500 mm (19.7 in) of X
- A 24,000 rpm high-speed spindle can be specified in place of the 10,000 rpm standard one
Limitations
- Holds 14 tools; the Robodrill α-D21MiB5 holds 21 on the same control
- No rotary axis travel or rotary table figures are listed, so that hardware must be confirmed with the supplier
- The faster spindles are extras: 10,000 rpm is what the standard machine has

Frequently Asked Questions
01
Z travel. The Robodrill α-D14MiB5 has 330 mm (13 in) of Z and this model has 400 mm (15.7 in), about 21% more. The 500 mm (19.7 in) X travel, 400 mm Y travel, 14 tools and FANUC Series 31i-B5 Plus control are unchanged.
02
No. The Robodrill α-D14MiBADV lists the FANUC Series 31i-B Plus; this model lists the Series 31i-B5 Plus, described in the table as 5-axis capable. Both have 500 x 400 x 400 mm (19.7 x 15.7 x 15.7 in) travels and 14 tools.
03
14 tools. That count has to cover every face machined in one clamping, so check the tool list of the most demanding part before choosing this model. The Robodrill α-D21MiB5 carries 21 tools on the same control but has 330 mm (13 in) of Z.
