Machine Comparison
FANUC ROBOCUT C400iB vs Mitsubishi MP1200
FANUC vs Mitsubishi Electric · Wire EDM
Summary
The FANUC ROBOCUT C400iB and the Mitsubishi MP1200 are wire EDMs of the same size. Both have 400 mm of X travel and 300 mm of Y travel, and both carry workpieces up to 500 kg. The differences in the table are small and specific.
The FANUC ROBOCUT C400iB has more Z travel, 255 mm (10.04 in) against 220 mm, so it takes taller workpieces. The Mitsubishi MP1200 reaches finer wire: the standard ranges are 0.1 - 0.3 mm on the FANUC and φ0.10 - 0.30 mm on the Mitsubishi, which adds φ0.05 and 0.07 mm wire as an extra-cost option. Machine weights are 3,200 kg (7,055 lb) and 3100 kg, the Mitsubishi figure including the dielectric fluid reservoir.

Advantages
FANUC ROBOCUT C400iB
- 255 mm (10.04 in) of Z travel against 220 mm, for taller workpieces
- Listed for precision die components, finish-critical parts and steep tapers
Mitsubishi MP1200
- Optional φ0.05 and 0.07 mm fine wire, below the 0.1 mm minimum listed for the FANUC ROBOCUT C400iB
- Listed for small punches and die inserts, and for shops short of floor space
Verdict
For work inside a 400 x 300 mm X-Y envelope and 500 kg, either machine fits, and the table does not separate them on travel or load. Choose the FANUC ROBOCUT C400iB when part height matters, since it has 255 mm (10.04 in) of Z travel against 220 mm. Choose the Mitsubishi MP1200 when the work calls for fine wire, since its optional φ0.05 and 0.07 mm wire goes below the 0.1 mm minimum of the FANUC ROBOCUT C400iB.
