Advantages
Makino BX3
- Tighter positioning accuracy at Sub-micron (glass scale feedback) for precision-critical work
- Backed by Makino's dealer and service network for parts and support
- Connector mold shops burning micro-pin cavities, micro-slots, and fine-pitch features in hardened mold steels
ONA QX4
- Greater x travel of 400 mm (15.7 in) accommodates larger workpieces
- Greater y travel of 300 mm (11.8 in) accommodates larger workpieces
- Greater z travel of 350 mm (13.8 in) accommodates larger workpieces
- Superior table size at 650 x 450 mm (25.6 x 17.7 in) vs 300 x 250 mm (11.8 x 9.8 in)
- Superior max workpiece weight at 1,000 kg (2,205 lb) vs 150 kg (331 lb)
Verdict
The ONA QX4 edges ahead on specifications in this comparison, particularly in X Travel and Y Travel. However, the Makino BX3 remains competitive and may be the better choice depending on price, dealer support in your area, or specific workholding and tooling considerations. Both are capable machines — the best decision comes from running your actual parts and evaluating total cost of ownership including tooling, training, and service.
