How much does the FANUC RoboDrill a-D21SiB5 ADV Plus cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from FANUC. Configuration moves it a long way.
Overview
The FANUC RoboDrill a-D21SiB5 ADV Plus is a compact BT30 / BBT30 machining center built around a 24,000 RPM spindle, which the listed figures give as standard on the ADV Plus. Travels are 300 mm (11.8 in) in X and Y and 330 mm (13.0 in) in Z, over a 500 x 300 mm (19.7 x 11.8 in) table with a load of 100 kg (220 lb).
Read the two spindle ratings together. The 26 kW (35 hp) is a peak figure, and the torque row gives 12 Nm continuous. A spindle with that balance accelerates hard and drills, taps and mills with small tools at high surface speed. Continuous torque of 12 Nm will not push a large face mill through steel, so plan cuts around small-diameter tooling and high feed instead of depth of cut.
The 100 kg (220 lb) table limit covers everything bolted down: vise or fixture plate, any rotary unit, and the part. That matters for the DDR 5-axis option, listed as available with an A-axis of -120/+30 deg and a C-axis of 360 deg continuous. No separate load is given for it. The RoboDrill a-D14MiB5 is listed at 200 kg (441 lb), so a job that needs heavy workholding belongs on that machine.
Rapids are 54 m/min (2,125 ipm) on all axes, and the 21-position turret changes in 0.7 sec tool-to-tool and 1.3 sec chip-to-chip. The machine occupies 1,750 x 1,600 mm (68.9 x 63.0 in), weighs 3,500 kg (7,716 lb) and runs the FANUC 31i-B5 Plus control.

Strengths & Limitations
Strengths
- 24,000 RPM spindle listed as standard on the ADV Plus, with 26 kW (35 hp) peak
- 54 m/min (2,125 ipm) rapids on all axes
- Small footprint of 1,750 x 1,600 mm (68.9 x 63.0 in)
- DDR 5-axis option is listed as available, with A-axis -120/+30 deg and C-axis 360 deg continuous
- 21-position turret changes in 0.7 sec tool-to-tool and 1.3 sec chip-to-chip
Limitations
- Continuous spindle torque is 12 Nm, which restricts roughing with large cutters
- Table load is 100 kg (220 lb), half the 200 kg (441 lb) listed for the RoboDrill a-D14MiB5
- The 26 kW (35 hp) figure is a peak rating, not a continuous one
- The DDR 5-axis unit is an option, so a base machine has linear axes only

Frequently Asked Questions
01
The listed figure is 12 Nm continuous, alongside 26 kW (35 hp) of peak power and a top speed of 24,000 RPM. That combination suits small tools run fast. For roughing with large-diameter cutters the continuous torque is the limit to check, not the peak power.
02
100 kg (220 lb) on a 500 x 300 mm (19.7 x 11.8 in) table. Add up the fixture, any rotary unit and the workpiece before loading it. The RoboDrill a-D14MiB5 is listed at 200 kg (441 lb) if the setup comes out heavier than this machine allows.
03
The DDR 5-axis option is listed as available, with an A-axis of -120/+30 deg and a C-axis of 360 deg continuous. It is an option row, so confirm whether a particular machine has the unit fitted. The other rows describe the 300 mm (11.8 in), 300 mm (11.8 in) and 330 mm (13.0 in) linear travels.
04
Both are listed with a 500 x 300 mm (19.7 x 11.8 in) table and a 100 kg (220 lb) load. The Robodrill α-D14SiB5ADV Plus has 14 tools, 400 mm (15.7 in) of Z and a 10,000 rpm spindle with 24,000 rpm optional. This model lists a 21-position turret, 330 mm (13.0 in) of Z and 24,000 RPM as standard.
