How much does the Fanuc Robodrill D21MiB5 Advance 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 D21MiB5 Advance is a BT30 / BBT30 vertical machining center with 500 mm (19.7 in) of X travel, 400 mm (15.7 in) of Y and 330 mm (13 in) of Z, on the Fanuc 31i-B5 control. Its listed table is more useful than most for tooling, because it states what the 21-tool turret will carry: a maximum tool diameter of 80 mm (3.1 in), a maximum length of 250 mm (9.8 in) and a maximum weight of 3 kg (6.6 lb).
Those limits shape the tool list. An 80 mm (3.1 in) face mill fits, but with its holder it has to stay under 3 kg (6.6 lb), which rules out heavy shell mill bodies and long boring bars. Put angle heads and large taps on a scale with their holders before assuming they can go in the magazine.
Two spindles are described. The 10,000 RPM spindle peaks at 14.2 kW (19 hp) and delivers 79.7 Nm (58.8 ft-lbf) at 1,700 RPM, which is the one for tapping and steel. The optional 24,000 RPM spindle peaks at 26.0 kW (35 hp). Both power figures are peak ratings, and no torque is listed for the faster spindle.
The 650 x 400 mm (25.6 x 15.7 in) table carries 300 kg (660 lb), and the spindle nose sits 250-580 mm (9.8-22.8 in) above it. With the nose never closer than 250 mm, short tools on a low part will not reach, so plan fixture height accordingly. Cutting feed goes up to 30,000 mm/min (1,181 ipm) and rapids to 54 m/min (2,125 ipm).

Strengths & Limitations
Strengths
- Tool limits are stated: 80 mm (3.1 in) diameter, 250 mm (9.8 in) length and 3 kg (6.6 lb) weight
- 79.7 Nm (58.8 ft-lbf) of spindle torque at 1,700 RPM on the 10,000 RPM spindle
- Tool changes of 0.7 sec tool-to-tool and 1.3 sec chip-to-chip from a 21-tool turret
- 650 x 400 mm (25.6 x 15.7 in) table rated for 300 kg (660 lb)
- Cutting feedrate up to 30,000 mm/min (1,181 ipm), with rapids of 54 m/min (2,125 ipm)
Limitations
- Tools heavier than 3 kg (6.6 lb) or wider than 80 mm (3.1 in) cannot go in the changer
- Z travel is 330 mm (13 in), against 400 mm (15.7 in) on the Robodrill α-D14MiB5ADV Plus
- Standard spindle speed is 10,000 RPM; the 24,000 RPM spindle is optional
- The spindle nose comes no closer than 250 mm (9.8 in) to the table, so low parts need raising

Frequently Asked Questions
01
The listed maximum tool diameter is 80 mm (3.1 in), the maximum length is 250 mm (9.8 in) and the maximum weight is 3 kg (6.6 lb). Weigh large face mills and angle heads together with their holders before loading them.
02
The spindle power row gives 14.2 kW (19 hp) peak for the 10,000 RPM spindle and 26.0 kW (35 hp) peak for the 24,000 RPM spindle. Torque is 79.7 Nm (58.8 ft-lbf) at 1,700 RPM, stated for the 10,000 RPM spindle only.
03
Z travel is 330 mm (13 in) and the spindle nose to table distance runs 250-580 mm (9.8-22.8 in). Subtract fixture height and tool length from the upper figure to find the tallest part that clears. The Robodrill α-D14MiB5ADV Plus is listed with 400 mm (15.7 in) of Z if more stroke is needed.
04
Positioning accuracy is ±0.003 mm (±0.00012 in) and repeatability is ±0.002 mm (±0.00008 in). Those are axis figures; what a part holds also depends on fixturing, tooling and temperature in the shop.
