How much does the FANUC Robodrill α-D14MiB 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-D14MiB Plus is the plainest of the 500 mm Robodrills: 500 x 400 x 330 mm (19.7 x 15.7 x 13 in) of travel, 14 tools and the 3-axis FANUC Series 31i-B Plus control. Every sibling listed beside it adds something to this specification, so the useful question is which of those additions a given job needs.
Tool count is the first. The Robodrill α-D21MiB keeps the same travels and control and holds 21 tools. Z height is the second: the Robodrill α-D14MiBADV has 400 mm (15.7 in) of Z against 330 mm here. The third is the control, where the Robodrill α-D14MiB5 swaps in the Series 31i-B5 Plus on otherwise identical figures.
What all of them share is the spindle line-up. The standard spindle reaches 10,000 rpm, enough for drilling, tapping and general milling with small and medium cutters. FANUC lists a 12,000 rpm tapping / high-acceleration spindle and a 24,000 rpm high-speed spindle as options. If a part fits in 330 mm of Z with its fixture and longest tool, and its operations fit in 14 tools, nothing in the listed figures argues for the larger variants.

Strengths & Limitations
Strengths
- 500 x 400 mm (19.7 x 15.7 in) of X/Y travel, the same as the taller and larger-capacity siblings listed beside it
- Standard 10,000 rpm spindle, with 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles available as options
- FANUC Series 31i-B Plus control in a plain 3-axis configuration
Limitations
- Z travel is 330 mm (13 in); the Robodrill α-D14MiBADV offers 400 mm (15.7 in) on the same X and Y
- Holds 14 tools, where the Robodrill α-D21MiB holds 21 on the same travels
- The 24,000 rpm spindle is an option, not the standard fit

Frequently Asked Questions
01
14. The Robodrill α-D21MiB is the 21-tool model with the same 500 x 400 x 330 mm (19.7 x 15.7 x 13 in) travels and the same Series 31i-B Plus control, so the choice between the two comes down to how many tools a job, or a family of jobs, keeps loaded.
02
330 mm (13 in). That stroke has to cover the fixture, the part and the longest tool together. Where that is tight, the Robodrill α-D14MiBADV has 400 mm (15.7 in) of Z on the same 500 mm X and 400 mm Y travels.
03
The standard spindle runs to 10,000 rpm. Two faster spindles are listed as options: a 12,000 rpm tapping / high-acceleration spindle and a 24,000 rpm high-speed spindle. The listed figures give no power or torque for any of them.
