Is this the end of High Wire EDM filter costs?

With proven success in both cost cutting and process improvement using Magnom filters, a wire EDM machine filter replacement has doubled filter life and reduced contamination

With proven success in both cost cutting and process improvement within the EDM hole drilling environment it was a natural progression to examine the potential of Magnom within Wire EDM.

Wire EDM is now a firmly established technology within the modern toolroom environment.

It offers accuracy, speed and the possibility of long periods of unmanned operation thanks to improvements in automatic wire threading technology.

Whilst technology has moved forward in many areas of WEDM most machines still rely on simple disposable paper cartridge filter media.

These are expensive to buy and with recent environmental legislation changes disposal will become increasingly expensive.

A Magnom was recently fitted to a Sodick A535 machine by Greg Simmonds, Managing Director of Central EDM.

When asked of his experiences with Magnom Greg commented: "Since fitting the Magnom to our machine, we have noticed an increase in filter life of more than double.

This would constitute a significant saving over a twelve month period when fitted to our seven WEDM machines".

From the experience gained FCS has now produced units specifically for machine tool environments.

These units offer the potential for even greater improvements in filter life, less downtime and visual condition monitoring.

The Magnom is a revolutionary device which comprises a series of annular magnets and innovatively designed steel plates.

The Magnom removes ferrous, and some non-ferrous, contamination to less than one micron in a variety of fluids such as deionised water, hydraulic oil, lubricating oils and machine tool coolants.

The ability to remove contaminants to this degree makes it truly unique and its application within a system ensures that consistent WEDM performance is maintained.

In the Magnom core, where separation takes place, the fluid passes through highly concentrated "field effect" zones, where the contaminant is drawn into special collection areas which have significantly more dirt-holding capacity than conventional filter elements.

Unlike conventional filter elements, the core is easy to clean and re-use.

Due to the unique design of these collection areas, fluid flow is not obstructed, there is no appreciable pressure drop incurred, and the Magnom does not "block".
