Advantages
FANUC ROBODRILL D14MiA5
- Compact 300 x 300 mm (11.8 x 11.8 in) envelope for small parts
- Sized for dense cells where several machines share one robot
Fanuc Robodrill D21MiB5 Advance
- 500 x 400 mm of X/Y travel against 300 x 300 mm
- 300 kg (660 lb) table load against 100 kg (220 lb)
- 14.2 kW (19 hp) peak spindle rating against 3.7 kW (5 HP) continuous
- ±0.003 mm positioning accuracy against ±0.004 mm
Verdict
Choose by part size. The D14MiA5 suits small electronics housings, implant parts and watch components that fit a 300 x 300 mm envelope, especially in dense robot-tended cells. The D21MiB5 Advance suits the same kind of high-volume work on larger fixtures, castings and multi-part setups, where 500 mm of X travel, a 300 kg table and the higher spindle rating are needed.
