Eclipse Magnetic Filters Cut Costs at Machine Shop

Micromag magnetic filters from Eclipse Magnetics have improved productivity at Collison-Goll, a precision machine shop in Toronto. When Glenn Healey, plant manager, installed the magnetic filters on his company's screw and CNC machines, he was expecting to see cost savings on cutting oil and filter media. He additionally found that drill bodies no longer crashed because their through-holes had become plugged with oil and that Collison-Goll's spend on replacement drill bodies had dropped by 75 per cent.

The company has a central filtration system for cutting oil, but decided to take advantage of the benefits of magnetic filtration, installing individual Micromag MM20s on four machines. Magnetic filters remove ferrous and paramagnetic particles down to less than a micron in size - much smaller than the particles removed by barrier filters. Although small, these particles can still reduce the effectiveness of oils and lubricants, adversely affect cutting tools and product surface finish and cause other problems, such as the blocking of drill-body through-holes. No filter consumables are used and removed contamination can be recycled, reducing disposal costs.
