Machine Comparison
Mitsubishi EA12V vs ONA QX4
Mitsubishi Electric vs ONA Electroerosion · Sinker EDM
Summary
The Mitsubishi EA12V and the ONA QX4 are sinker EDMs of the same working size: both have 400 mm (15.7 in) of X travel and 300 mm (11.8 in) of Y travel, and both are aimed at mold inserts, core pins and die details.
The ONA QX4 has more capacity on paper: 350 mm (13.8 in) of Z travel against 300 mm, a 1,000 kg (2,205 lb) table load against 700kg, and a 100 kg (220 lb) maximum electrode weight against 50kg. The Mitsubishi runs the FP80V generator with Fine Pulse 2 and an M700 PC-based touchscreen CNC; the ONA uses its own digital generator with adaptive spark control and a touchscreen CNC. The EA12V is the lighter machine at 3,856 kg (8,500 lb) against 4,200 kg (9,259 lb).

Advantages
Mitsubishi EA12V
- FP80V generator with Fine Pulse 2 (FP2)
- M700 PC-based touchscreen CNC
- Saddle-less design aimed at shops short of floor space
- Lighter at 3,856 kg (8,500 lb) against 4,200 kg (9,259 lb)
ONA QX4
- 350 mm (13.8 in) Z travel against 300 mm (11.8 in)
- 1,000 kg (2,205 lb) table load against 700kg
- 100 kg (220 lb) maximum electrode weight against 50kg
Verdict
For heavier work, the ONA QX4 is the better fit: it takes a 1,000 kg workpiece, a 100 kg electrode and 350 mm of Z travel. The Mitsubishi EA12V suits mold and die shops whose inserts and electrodes stay within 700kg and 50kg, that want the FP80V generator and M700 control, or that need a saddle-less machine for limited floor space.
