Benefits of QX Technology

  • A 100% digital generator totally configurable and programmable.
  • Savings in electrodes, wear is reduced up to 500%. The generator optimises the erosion process and adapts it to the discharge conditions of each moment.
  • Full digital adjustment of eroding spark up to 30 different parameters allows optimizing erosion to its best.
  • Unique technological innovation. Generator 30% more powerful than the rest of the market. It is capable of reaching up to 400 A in intensity.
  • Powerful control with up to 8 simmultaeously interpolating axes and volumetric compensation in the entire work area.

Commercial Convention: SO GOOD, SO ONA

This month has been very special for ONA as we have hosted our first international sales convention: SO GOOD, SO ONA. Sales representatives and distributors from 11 countries visited us on 16 and 17 June...



Constant flow of information on the machine to guarantee its perfect working, with a reduction in costs and the optimization of production processes.



We are committed to the design of increasingly autonomous and efficient machines with the maximum number of hours without downtime.



simolges“We chose ONA because of its high-quality equipment, its excellent services, and the good supplier/customer relationship it offers. We always recommend ONA“ SIMOLDES GROUP (PT)
stikel“We chose ONA because they are leaders in large machines, AV130 is the largest wire-cut EDM on the market. Moreover, it is so reliable that it works unsupervised every day of the week, and it maintains its high cutting speed.” STICKEL (Alemania)
hpm“We have found in ONA a solution provider partner with values similar to ours. Thanks to their technical capacity and knowledge, we can respond to the demands of clients like Safran.” HOURAT (FR)

GE Power

“The average working time of our ONA machines exceeds 96% active time.”

concours“Acquiring a double head ONA TQX10 and 2 robot changers with 132 positions will ensure superior working times and quality. An investment designed for our future. This is our tomorrow.” CONCOURS MOLD (USA)
