Machine Comparison
ONA QX4 vs ONA QX6
ONA Electroerosion vs ONA Electroerosion · Sinker EDM
Summary
The ONA QX4 and ONA QX6 are two sizes of ONA's sinker EDM with the same generator, control, 2 um positioning, 1 um repeatability and VDI 10 (Ra 0.4 um) best finish.
The QX6 is the bigger machine in every working dimension: 650 x 450 x 450 mm of travel against 400 x 300 x 350 mm, a 900 x 600 mm table against 650 x 450 mm, 2,000 kg (4,409 lb) of workpiece load against 1,000 kg (2,205 lb), and a 200 kg (441 lb) electrode limit against 100 kg (220 lb). The QX4 is the smaller, lighter machine at 4,200 kg (9,259 lb) against 6,500 kg (14,330 lb), on 2,200 x 2,100 x 2,700 mm of floor against 2,800 x 2,500 x 2,900 mm.

Advantages
ONA QX4
- Smaller footprint: 2,200 x 2,100 x 2,700 mm against 2,800 x 2,500 x 2,900 mm
- Lighter at 4,200 kg (9,259 lb) against 6,500 kg (14,330 lb)
ONA QX6
- 650 x 450 x 450 mm of travel against 400 x 300 x 350 mm
- 2,000 kg (4,409 lb) workpiece load against 1,000 kg (2,205 lb)
- 200 kg (441 lb) electrode weight against 100 kg (220 lb)
- 900 x 600 mm table against 650 x 450 mm
Verdict
Same accuracy and finish, so work size decides. The ONA QX6 is for large injection mold cavities, forging dies and die casting tooling that need 650 mm of X travel, up to 2,000 kg of workpiece and electrodes up to 200 kg. The ONA QX4 is for small to medium inserts, core pins and precision features within 400 x 300 mm, and fits shops where floor space is limited.
