Overview
The ONA AV80 is the large-format wire EDM in ONA Electroerosion's AV series, offering 800 x 600 x 500 mm (31.5 x 23.6 x 19.7 in) of X/Y/Z travel for shops that regularly cut workpieces too large for standard mid-range wire EDMs. Built in Durango, Spain, the AV80 targets mold and die operations working with large progressive dies, bumper molds, instrument panel molds, and other components where 600mm of X-travel simply is not enough. The 2,000 kg (4,409 lb) workpiece capacity means you can load substantial die blocks without worrying about the table limit.
The AV80 shares ONA's latest digital generator technology with the smaller AV60, providing adaptive spark control that continuously optimizes discharge parameters for the material and thickness being cut. Surface finish capability reaches Ra 0.15 um (6 uin) with multi-pass strategies, and the generator handles everything from brass and coated wires in the 0.15 to 0.30 mm range. Rough cutting speed on 50mm thick tool steel reaches approximately 320 mm2/min with 0.25 mm brass wire, putting the AV80 in competitive territory against comparable Mitsubishi and Sodick large-format machines.
The 500 mm of Z-axis travel paired with +/-100 mm of U/V axis travel gives the AV80 excellent taper cutting capability — up to +/-30 degrees over the full Z height. This is particularly valuable for cutting taper relief on thick die sections and for aerospace components requiring drafted surfaces. The water-jet automatic wire threading system handles start holes reliably, and the thread-through-kerf capability keeps the machine running through multi-opening cuts without operator intervention.
ONA's proprietary CNC control features a modern touchscreen interface with both conversational and ISO programming modes. An integrated edge-finding and workpiece alignment system reduces setup time. The single-piece cast iron base provides the thermal stability needed for long unattended cuts, and ONA backs the structure with a 5-year warranty. The dielectric system includes an oversized tank and chiller to maintain consistent temperatures during extended roughing cycles on thick stock.

Strengths & Limitations
Strengths
- 800 x 600 x 500 mm travel handles large progressive die sections, bumper molds, and aerospace components that exceed standard wire EDM envelopes
- +/-100 mm U/V travel provides generous taper cutting range, essential for thick die sections requiring relief angles
- 2,000 kg workpiece capacity accommodates heavy die blocks and mold plates without specialized fixturing
- Adaptive digital generator maintains consistent cutting performance across varying material thicknesses and types
- 5-year structural warranty from ONA reflects confidence in the cast iron base and build quality
- 500 mm Z-travel is among the largest available in this price class, reducing the need for an even more expensive large-format machine
Limitations
- Larger footprint at 3,400 x 3,000 mm requires significantly more floor space than mid-range wire EDMs
- ONA's North American service network is less established than Mitsubishi, Makino, or AgieCharmilles, potentially affecting response times
- Proprietary ONA control has a smaller user community than Fanuc or Mitsubishi-controlled wire EDMs
- Resale value in North America is lower than equivalent Japanese or Swiss machines due to lower brand recognition
- Machine weight of 7,500 kg may require floor reinforcement in shops not designed for heavy equipment

Frequently Asked Questions
01
New ONA AV80 machines typically price between $180,000 and $260,000 depending on options. This positions the AV80 competitively against similarly sized Mitsubishi and AgieCharmilles machines, which often price higher for equivalent travel.
02
The AV80 offers significantly more travel (800x600x500mm vs 600x400x400mm), larger U/V axis range (+/-100mm vs +/-75mm), and higher workpiece capacity (2,000 kg vs 1,500 kg). Both share the same generator and control platform. The AV80 costs roughly $60,000-$80,000 more than the AV60.
03
The AV80 cuts tapers up to +/-30 degrees over the full 500mm Z-height. The +/-100mm U/V travel range provides the geometric capability for these steep tapers on thick workpieces.
04
Yes. The automatic wire threading system, thread-through-kerf capability, and large wire spool capacity support extended unattended operation. The dielectric chiller maintains stable temperatures during long roughing cycles.
05
ONA machines are manufactured in Durango, in the Basque Country of Spain. ONA Electroerosion has been building EDM machines since 1952, making them one of the oldest EDM manufacturers in the world.
