How much does the ONA EX A30 cost?
Estimated price range
Our best estimate for a wire edm in this class — not a quote from ONA Electroerosion. Configuration moves it a long way.
Overview
The ONA EX A30 is listed with the figures of a die-sinking EDM: 600 mm (23.6 in.) of X travel, 400 mm (15.7 in.) of Y, an electrode holder that travels 400 mm (15.7 in.), and a drop tank around an 800 x 600 mm (31.5 x 23.6 in.) table. Nothing in the table refers to wire diameter, wire guides or taper, so judge the machine as a sinker.
The table is rated for 1500 kg (3306 lbs.) and the head sits up to 675 mm (26.6 in.) above it. Electrode, holder and workpiece all have to fit inside that distance, and the 400 mm (15.7 in.) of holder travel then decides how deep a cavity can be burned in one clamping. A separate row gives a maximum weight of 300 kg (661 lbs.) without naming what it applies to. Because the table load has its own row, the 300 kg figure probably concerns the electrode, but have it confirmed before hanging a heavy electrode on the head.
Three more rows read length 1070 mm (42.1 in.), width 770 mm (30.3 in.) and height 450 mm (17.7 in.). They are far too small to be the outline of a machine that weighs 4900 kg (10802 lbs.) and they sit close to the table size, so they read as the usable tank or workpiece space. The table does not say which.
Generator intensity is listed as 100/200/400 A. Those are three ratings, not one, and the rating fitted to a given machine sets how quickly a large electrode can rough. The finish row gives 0.08 – 0.1 µm Ra (3.1 – 3.9 µin Ra), which describes the finest finish reached with the lowest settings and has nothing to do with roughing output.

Strengths & Limitations
Strengths
- X and Y travels of 600 mm (23.6 in.) and 400 mm (15.7 in.) over an 800 x 600 mm (31.5 x 23.6 in.) table
- Table load capacity of 1500 kg (3306 lbs.) for mould bases and die blocks
- 400 mm (15.7 in.) of electrode holder travel under a head that sits up to 675 mm (26.6 in.) above the table
- Listed finish of 0.08 – 0.1 µm Ra (3.1 – 3.9 µin Ra)
- Drop tank table type, so the tank lowers clear of the table for loading and setup
Limitations
- Generator intensity is listed as 100/200/400 A; the table does not say which rating a given machine carries
- The 300 kg (661 lbs.) maximum weight row does not state whether it applies to the electrode or to something else
- The length, width and height rows (1070 x 770 x 450 mm) are not labelled as tank, workpiece or machine dimensions
- At 4900 kg (10802 lbs.) the machine needs a floor and a rigging plan to match

Frequently Asked Questions
01
The listed figures are die-sinking figures: an electrode holder with 400 mm (15.7 in.) of travel, a generator intensity of 100/200/400 A and a drop tank. The table has no wire diameter, wire guide or taper row, so compare it with other sinkers when sizing a job.
02
The table measures 800 x 600 mm (31.5 x 23.6 in.) and carries up to 1500 kg (3306 lbs.). X and Y travels are 600 mm (23.6 in.) and 400 mm (15.7 in.), and the head sits up to 675 mm (26.6 in.) above the table. Rows for length, width and height give 1070 x 770 x 450 mm without saying whether they describe the tank or the workpiece.
03
The generator intensity row reads 100/200/400 A. The table does not tie one of those ratings to the base machine, so ask which generator a specific machine has. The finish row gives 0.08 – 0.1 µm Ra (3.1 – 3.9 µin Ra).
04
Machine weight is listed as 4900 kg (10802 lbs.). Add the dielectric and the heaviest job expected, up to the 1500 kg (3306 lbs.) table load, when checking the floor.
