ONA QX4 vs Sodick AG40L
ONA Electroerosion vs Sodick · Sinker EDM
Summary
The ONA QX4 and Sodick AG40L are compact sinker EDMs with the same 400 mm (15.7 in) X and 300 mm (11.8 in) Y travel and a best finish of Ra 0.4 um on both, listed as VDI 10 on the ONA and VDI 12 / Ra 0.40 um with graphite on the Sodick.
The QX4 offers more vertical room and capacity: 350 mm (13.8 in) of Z travel against 270 mm (10.63 in), and a 1,000 kg (2,205 lb) workpiece load against 550 kg (1,213 lb). The AG40L is the more compact machine, with a 1,550 x 2,350 x 2,330 mm footprint against 2,200 x 2,100 x 2,700 mm, and it weighs 3,900 kg (8,598 lb) against 4,200 kg (9,259 lb). It runs the TMM3 power supply and Sodick LQ controller.

Advantages
ONA QX4
- 350 mm (13.8 in) Z travel against 270 mm (10.63 in)
- 1,000 kg (2,205 lb) workpiece load against 550 kg (1,213 lb)
Sodick AG40L
- Smaller footprint: 1,550 x 2,350 x 2,330 mm against 2,200 x 2,100 x 2,700 mm
- Lighter at 3,900 kg (8,598 lb) against 4,200 kg (9,259 lb)
Verdict
The two cover the same X/Y area to the same finish, so part height and weight decide. The ONA QX4 suits shops sinking deeper features or heavier inserts and die blocks, with 350 mm of Z travel and a 1,000 kg load. The Sodick AG40L suits mold shops burning core pins, cavity inserts and carbide details in production, where a smaller, lower machine fits the floor.
