Fanuc vs FANUC · Vertical Machining Centers
Summary
The Fanuc Robodrill α-D21MiB5 and FANUC ROBODRILL D14MiA5 are 30-taper drill-tap machines that share a lot: 330 mm of Z travel, a 10,000 RPM spindle (24,000 RPM optional), a 21-tool turret, 0.7 sec tool changes, 54 m/min rapids, ±0.004 mm positioning and a Fanuc 31i-B5 control. They sit in different size classes, though.
The α-D21MiB5 has 400 mm (15.7 in) of Y travel against 300 mm (11.8 in), a 750 x 400 mm table against 500 x 300 mm, and a 300 kg (661 lb) load limit against 100 kg (220 lb). Its spindle is rated 11 kW (15 hp) standard against 3.7 kW (5 HP) continuous. The D14MiA5 is the lighter machine at 2,700 kg against ~3,900 kg.

Advantages
Fanuc Robodrill α-D21MiB5
- 400 mm (15.7 in) of Y travel against 300 mm (11.8 in)
- 300 kg (661 lb) table load against 100 kg (220 lb)
- 11 kW (15 hp) standard spindle against 3.7 kW (5 HP) continuous
- 750 x 400 mm table against 500 x 300 mm
FANUC ROBODRILL D14MiA5
- Lighter at 2,700 kg (5,952 lb) against ~3,900 kg (8,598 lb)
- Compact machine suited to dense cells of several machines served by one robot
Verdict
These two serve different part sizes. The D14MiA5 suits small aluminum, titanium and brass parts such as electronics housings, implants and watch components, where several compact machines can share one robot. The α-D21MiB5 suits larger fixtures and multi-part setups in automotive and electronics production, where a 750 x 400 mm table, a 300 kg load and an 11 kW spindle are needed.
