Magnetic unit ups EDM dielectric additive life

A magnetic filtration device has increased the life of dielectric additive by almost 75% when drilling holes, says a subcontract EDM company, as well reducing foaming.

With proven success in grinding, deep hole drilling, automotive and hydraulic applications it was no surprise to discover a further application for Magnom technology.

Mark Wingfield and Arthur Watts, Directors of AM EDM (0121 558 8352) have recently fitted a Magnom module to the dielectric system of a Sodick K1C EDM hole drilling machine to enhance performance, extend fluid life, reduce foaming and improve the overall cleanliness of the system.

When asked of his experiences with Magnom, Wingfield commented: "The results speak for themselves - We have increased the life of our dielectric additive by almost 75%; this alone justifies buying a Magnom.

We have also noticed a reduction in dielectric foaming, particularly when drilling larger holes.

The unit is easy to clean and our machine is performing better than ever." Excess contaminant within a dielectric system causes poor EDM performance and wear and failure on critical components such as pumps.

Installing Magnom ensures filtration to a much finer level than is normally achieved in an EDM hole drilling system with the associated process benefits.

This is all done without the problems of flow restriction and blockages associated with conventional filtration.

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 cooling 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 complete protection from the hardest wear-inducing particles 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".
