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.

ONA AF 25 EDM History / ONA EDM

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.
