Wire EDM – Modular-range machines – ONA AF MODULAR Series

Wednesday, June 27th, 2012

Over 20 different models of large die-sinking EDM machines

  • The large scale ONA AF MODULAR series, uses a modular design to allow many configurations. Each customer can configure, with a great flexibility, the machine that meets his exact requirements.
  • This new series utilizes pre-built axes modules to drastically reduce machine assembly time.
  • Each customer can get a custom system for the same price and lead time as a standard machine.

Manifold configurations of X-Y-Z travels

  • X travel: 31.5, 39.4, 59.1 or 78.7 in.
  • Y travel: 23.6, 31.5, 39.4 or 51.2 in.
  • Z travel: 19.7, 23.6 or 27.5 in.

Highly rigid mechanical structure

  • Constructed of stabilized fine grained cast iron blended with graphite.
  • Fixed bedframe machine.
  • That allows work pieces up to 22.000 lbs.  AF130 Wire EDM   Modular range machines   ONA AF MODULAR Series

Maximum productivity

The new ONA AF MODULAR machines are noted for the high cutting speed (42 in2/minute with wire of 0.013 in diameter and 34 in2/minute with wire of 0.010 in diameter) and low maintenance costs, thanks to the ecological filtration system, ONA AquaPrima, which does not require replaceable cartridges.

Surface integrity 100% preserved

The ONA AF MODULAR series includes the ONA Easycut generator, which provides a cut that is 100% free from electrolyte corrosion, without affecting the speed, and while preserving the surface integrity of the material being cut (best surface finish: 0.2 µm Ra – 6 VDI).

6 axes controlled by the CNC

The AF MODULAR models incorporate the latest generation CNC, ONA-W64, able to control 6 axes, 5 of them (B, X, Y, U, V) at the same time, enabling the machine to incorporate a rotation axis which is totally controlled by the CNC.

ONA EDM Cartridge-less Filtration

Wednesday, August 31st, 2011

ona aqua prima fiter8 27 2011 10 55 38 AM ONA EDM Cartridge less Filtration

First let’s examine the reasons why you might consider Cartridge-less filtration:

• “Going Green” is an important trend in both manufacturing in general and EDM in particular. Last September, at IMTS, many of the OEM’s prominently displayed significant advances in EDM technology directed at reducing the impact of EDM on our environment. As responsible inhabitants of this planet, we all share in the responsibility to protect the environment for future generations. Discarded filters impact the environment in one way or another. They either end up in landfills (possibly contributing to groundwater contamination) or they are incinerated (contributing to increased carbon emissions).

• Eliminating the costs associated with buying and maintaining an inventory of filter cartridges.
• Eliminating the maintenance cost and downtime associated with filter changes.
• Eliminating the expense and responsibility of disposing of used filter cartridges.

Cartridge-less Filtration systems offer an alternative solution to the problem of providing a continuous supply of clean water to the Wire EDM process.

What about aluminum?
Consider the not so uncommon case of cutting aluminum. Due to the tendency of flaky aluminum EDM debris to clog filter elements, it is not uncommon to get less of the filter life expected when cutting Steel. For those EDMer’s who regulary cut aluminum, they can enjoy incredible savings of more the $20,000.00 per year. This greatly lowers the const of ownership ONA Cartridge-less Technology is only sold with ONA Machines.

EDM History / ONA EDM

Monday, May 23rd, 2011

In 1770, English physicist  Joseph Priestle studied the erosive effect of electrical discharges. Furthering Priestley’s research, the EDM process was invented by two Russian scientists, Dr. B. R. Lazarenko and Dr. N. I. Lazarenko, in 1943. In their efforts to exploit the destructive effects of an electrical discharge, they developed a controlled process for machining of metals. Their initial process used a spark machining process, named after the succession of sparks (electrical discharges) that took place between two electrical conductors immersed in a dielectric fluid. The discharge generator effect used by this machine, known as the Lazarenko circuit, was used for many years in the construction of generators for electrical discharge.

Additional researchers entered the field and contributed many fundamental characteristics of the machining method we know today.

What is ONA the Dielectric System? Save $5,125.00 Annually

Friday, May 6th, 2011

Wire EDM uses deionized water as the dielectric medium compared to Vertical EDM’s that use oil.  The dielectric system includes the water reservoir, filtration system,  deionization system, and water chiller unit.  During machining, the dirty water from cutting is drained into the dirty, unfiltered side of the dielectric reservoir, where the water is then pumped and filtered to 3 microns through a mineral bed vessel, and returned to the clean side of the dielectric tank.  When the vessel approaches its capacity and reaches a set pressure, the unit automatically back flushes the material (swarf) into a separate decant tank, where the material decants  (settles) in the water. This is an exclusive ONA patented  maintenance free, lifetime filtration system.   You never have to purchase paper filter elements or worry about their disposal.  This equates to tremendous cost savings per year.

Following filtration, the clean water is measured for  conductivity, and if required, automatically passes through a vessel that contains a mixed bed of  anion and cation beads.  This mixed bed resin (ion exchange unit) controls the resistivity of the water to set values.

Note: Deionized water is an efficient insulator.  Untreated water is a conductor and would cause unstable cutting, wire breaks and not be usable in the EDM process.  The clean, filtered water now flows into the clean side of the dielectric  reservoir and proceeds to the cutting area.  Used water is drained and returned to the unfiltered, dirty side of the dielectric reservoir to complete the cycle.  A water chiller  is also provided as standard equipment to keep the dielectric, workpiece, worktable, control arms, and fixtures thermally stable.

The quality of the water is constantly measured.   During the cutting process the chips from the material that is being eroded, gradually change and increase the water conductivity level.   When this level becomes too high, the water is automatically directed to pass through the deionizing resin.to bring it to the  correct level.  Resistivity levels  of the water are set at the control according to the cutting requirements of the workpiece material being machined. Another additional cost savings and benefit ONA provides is their patented “EKOADD”.   By using this additive, the polarity of the eroded particles in the dielectric are “neutralized” causing them to cling and be joined together.  This additive extends the life of the resin by 50%  or more, and also helps clean the precision guides and power feed contacts while providing cleaner water.

ONA EDM – Best Filtration System In Industry!

ona filter ONA EDM   Best Filtration System In Industry!

Why would you buy a new EDM without this ONA EDM filtration system? This filter unit is designed to operate together with wire EDM’s, taking dirty water from the machine and filtering it to 3 microns to supply clean water for machining. When the filter vessel reaches it’s cleaning capacity, which is detected by a pressure switch, a backwashing cycle is initiated. While in the backwashing cycle, clean filtered water is supplied to the machine’s dielectric tank. Therefore, the machine has an endless supply of clean water. After a predetermined programmed number of backwashing cycles, a sludge removal cycle is initiated, discharging the sludge contained in the decanting tank into a sludge bag. When the sludge bag reaches it’s capacity an alarm will be generated.

Aquaprima AK-100 Filter unit is an automatic, self cleaning, mineral filter unit designed for WEDM filtration, and does not require filter media replacement.
