How much does the FANUC Robodrill α-D14MiB5 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-D14MiB5 Plus is a 14-tool compact machining center whose distinguishing row is the control: the FANUC Series 31i-B5 Plus, which the table describes as 5-axis capable. Travels are 500 mm (19.7 in) in X, 400 mm (15.7 in) in Y and 330 mm (13 in) in Z.
Set next to the Robodrill α-D14MiB, the mechanical figures do not change at all. That machine has the same travels, the same 14 tools and the same spindle choices, and runs the Series 31i-B Plus. The decision between the two rests on whether rotary-axis work is planned.
Two cautions follow from the table. It gives X, Y and Z travels only, with no rotary axis figures, so a buyer should establish exactly which rotary hardware a quotation includes. And 330 mm of Z is the shorter of the two strokes listed at this size: a rotary table and its fixture use up height before the part is even loaded. The Robodrill α-D14MiB5ADV keeps this control and tool count and has 400 mm (15.7 in) of Z.
The standard spindle is 10,000 rpm. Spindles for 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed work are optional.

Strengths & Limitations
Strengths
- FANUC Series 31i-B5 Plus control, listed as 5-axis capable
- Same 500 x 400 x 330 mm (19.7 x 15.7 x 13 in) travels as the Robodrill α-D14MiB, so a part that fits one fits the other
- Optional 24,000 rpm high-speed spindle for small-tool work; 10,000 rpm is standard
Limitations
- 330 mm (13 in) of Z leaves limited height once a rotary table and fixture are mounted; the Robodrill α-D14MiB5ADV has 400 mm (15.7 in)
- 14 tools is modest for multi-face work; the Robodrill α-D21MiB5 holds 21 with the same control and travels
- The table lists no rotary axis travel, so the rotary hardware has to be confirmed separately

Frequently Asked Questions
01
The table lists its control, the FANUC Series 31i-B5 Plus, as 5-axis capable. The travels it gives are the three linear ones, 500 mm (19.7 in) in X, 400 mm (15.7 in) in Y and 330 mm (13 in) in Z, and no rotary axis figures are listed. Ask what rotary table, if any, is part of the machine as quoted.
02
Only in the control row. The Robodrill α-D14MiB lists the FANUC Series 31i-B Plus; this model lists the Series 31i-B5 Plus. Travels of 500 x 400 x 330 mm, the 14-tool capacity and the 10,000 rpm standard spindle with its 12,000 and 24,000 rpm options are the same on both.
03
Yes. The Robodrill α-D21MiB5 holds 21 tools with the same 500 x 400 x 330 mm travels and the same Series 31i-B5 Plus control. This model holds 14.
