Machine Comparison
Makino BX3 vs ONA QX4
Makino vs ONA Electroerosion · Sinker EDM
Summary
The Makino BX3 and ONA QX4 are both listed as sinker EDMs, but they do different jobs. The BX3 is an EDM drilling machine for cooling film holes in turbine blades and vanes, working on a rotary table. The QX4 is a die-sinking machine for small to medium mold inserts, core pins and die details, with a 650 x 450 mm (25.6 x 17.7 in) table.
The QX4 has slightly more X and Y travel, 400 mm (15.7 in) and 300 mm (11.8 in) against 370 mm (14.6 in) and 270 mm (10.6 in), and a far higher workpiece rating, 1,000 kg (2,205 lb) against 20 kg (44 lb). The BX3 has the longer Z stroke, 750 mm (29.5 in) against 350 mm (13.8 in).

Advantages
Makino BX3
- 750 mm (29.5 in) Z travel against 350 mm (13.8 in)
- Rotary table on A and B axes for drilling holes at many angles in blades and vanes
- Built for high-volume EDM drilling of small aero-engine part details
ONA QX4
- 1,000 kg (2,205 lb) workpiece load against 20 kg (44 lb)
- 650 x 450 mm (25.6 x 17.7 in) work table for mold inserts and die details
- 400 mm (15.7 in) X and 300 mm (11.8 in) Y travel against 370 mm (14.6 in) and 270 mm (10.6 in)
Verdict
These machines serve different processes. Choose the Makino BX3 for drilling cooling film holes in turbine blades and vanes, where the rotary table and 750 mm (29.5 in) of Z travel apply. Choose the ONA QX4 for sinking injection mold inserts, core pins, punch details and repair work on parts up to 1,000 kg (2,205 lb), a load the BX3 with its 20 kg (44 lb) rating is not built to carry.
