Maximum precision to the finest detail with the new ONA microhole EDM range.

At ONA, our product range now includes the experience of the North American company AA EDM manufacturing microhole EDM drilling machines.

At ONA, our product range now includes the experience of the North American company AA EDM manufacturing microhole EDM drilling machines.

Our commitment to EDM technology knows no limits.

We offer two types of specialised precision EDM drilling. Versatile, reliable, easy to operate machines with a long life ahead. Microhole EDM drilling machine, for the production of parts that require holes with a diameter of 0.08 mm to 0.4 mm. These machines use a tungsten ground rod as an electrode for machining the desired hole by EDM. Unlike other machines, the electrode does not rotate.

ONA can supply the EDM head that best suits the specific needs of each client. The microhole EDM machines, offer different possible heads: standard head, the double and triple heads or the K-FACTOR that can produce holes in circular and non-circular shapes, reverse taper holes, deep or shallow entry angles and small or large depth-to-diameter ratios.

Fasthole EDM drilling machine, for holes with a diameter of 0.3 mm to 6.0 mm. In general, these machines use brass tubular electrodes that rotate while drilling the hole. The machining speed is higher. Therefore, the wear of these electrodes is greater than in the microhole machining equipment.

 One of the most outstanding features of the ONA EDM drilling machines is its low maintenance cost due to several factors: the small size of the holes, the low current intensity and the limited wear of the tungsten electrode. An electrode is capable of drilling thousands of holes.

 A digital ONA generator and an intuitive CNC

The ONA generators boast a design featuring multiple processors, digital signal processing and a unique and highly intuitive interface. The power supply from 60 or 120 amps allows for very deep holes to be machined at high speeds while maintaining recast layer at minimum levels.

 The central core of the system is the pulse controller circui board. The floating point DSP processor coupled with Ethernet, EtherCat and fiber optics give precise control over all aspects of the EDM process such as breakthrough detection, electrode refeed, programmable electrode rotation and flushing.

 The CNC stands out for its intuitive operation, easy set-up and maintenance and for its durable components ensure a long life. Its special features make it the ideal option for complex tasks: small hole drilling applications with virtually any angle hole required is within its capability. Automation is also available on these machines as well as other custom options
