Precision mechanical engineering business Mollart Engineering Ltd is now installing Eclipse Magnetic’s Micromag magnetic filters on the majority of the multi-spindle gundrilling centres it designs, manufactures and supplies. As one of the world leaders in gundrilling centres for the pellet die industry, Mollart produces machinery used to make dies to create pellets from a variety of materials.
One of the main materials used to make the dies is a chrome alloy steel called XC40 which naturally produces a large amount of dust when drilled at high feed rates. This dust contaminates the oil, resulting in particles settling in the tank to create a thick paste-like substance which can easily block the pump and render it useless. Mollart has found a solution to this in the Micromag magnetic filter from Eclipse Magnetics, which efficiently filters the oil to remove the damaging particulate.
Ian Petitt, Sales Director for Deep Hole Drilling Systems at Mollart Engineering Ltd said: “We have been very successful with the Micromag in this application. It has resolved a lot of problems; it’s been a very good, usable tool for us. Not many machines go out without it now.”
On occasions where Mollart fit only one Micromag, it is used to polish the oil after it has gone through another form of media, usually paper, first. The oil is passed through the Micromag, and then through the heat exchanger in order to reduce the temperature. This is a continuous process; for machines that have a 2000 – 3000 litre tank, for instance, Mollart may only be using 100 – 250 litres per minute of oil. The Micromag itself is not directly in the high pressure oil line, therefore it is allowed to work at its own pace, and even if the machine isn’t working the polishing of the oil is still being carried out.
Ian Petitt continues “The good thing about Eclipse filters is that you don’t have disposable filtration elements, and that makes a big difference to disposal costs and general running costs. My main aim is to make sure my customers’ pumps work not only work effectively, but stay alive for as long as possible.
