How much does the FANUC Robodrill α-D14SiB5 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
FANUC builds the Robodrill α-D14SiB5 Plus on the Series 31i-B5 Plus, which its table describes as a 5-axis capable control, and that is the only row that differs from the Robodrill α-D14SiB. The rest matches: 300 mm (11.8 in) of X, 330 mm (13 in) of Z, a 500 x 300 mm (19.7 x 11.8 in) table and 14 tools.
A 5-axis capable control is not a 5-axis machine. FANUC's table for this model lists no rotary axes, so the tilting or rotary table is something to specify separately, and its weight comes out of the 100 kg (220 lb) table load before any fixture or part is added. On a table this small that budget goes quickly. Work out the rotary unit, the fixture and the heaviest part as one number first.
Z travel deserves the same check. With 330 mm (13 in) available, a rotary unit standing on the table takes height that the part and tool then cannot use. If the stack-up is tight, the Robodrill α-D14SiB5ADV keeps the same control and 14 tools and lists 400 mm (15.7 in) of Z. Y is listed as 300 mm (11.8 in) + 100 mm extension. The standard spindle runs to 10,000 rpm, with 12,000 rpm tapping / high-acceleration and 24,000 rpm high-speed spindles optional.

Strengths & Limitations
Strengths
- Series 31i-B5 Plus control, listed by FANUC as 5-axis capable
- Same 300 mm (11.8 in) X travel and 500 x 300 mm (19.7 x 11.8 in) table as the 3-axis Robodrill α-D14SiB
- Optional 24,000 rpm high-speed spindle for small tools
Limitations
- No rotary axes are listed; a rotary table must be specified and its weight counts against the 100 kg (220 lb) table load
- 14 tools can run short on multi-face parts; the Robodrill α-D21SiB5 carries 21 tools
- Z travel of 330 mm (13 in) is shared between rotary unit, fixture, part and tool

Frequently Asked Questions
01
FANUC's table for this model does not list one. It lists the Series 31i-B5 Plus as a 5-axis capable control, three linear travels and a 500 x 300 mm (19.7 x 11.8 in) table. Treat the rotary axes as equipment to be specified with the machine, and count their weight against the 100 kg (220 lb) table load.
02
In Z travel. This model has 330 mm (13 in) of Z and the Robodrill α-D14SiB5ADV has 400 mm (15.7 in). X travel, the table, the 14 tools and the Series 31i-B5 Plus control are listed the same for both.
03
14 tools. FANUC lists the Robodrill α-D21SiB5 with 21 tools on the same travels, table and control, which is the model to look at if a part needs more than 14 tools across its faces.
