Application Background

Based in Sheffield, South Yorkshire, OSL Cutting Technologies is a market leading supplier of specialist tools for the industrial engineer and fabricator. Products include magnetic drilling and hole cutting systems for a diverse range of applications including sheet metal and fabrication, general engineering, construction and utilities, electrical, automotive and transportation accessory fitting, and general trades and DIY. OSL Cutting Technologies utilise 3 Walter tool grinding machines to aid them in the manufacture of components used to make its products.

Problem

OSL Cutting Technologies had previously used a number of different filtration methods on its Walter grinding machines, including 2 MicroMag magnetic filters from Eclipse Magnetics. However, due to the high volumes of oil passing through these smaller filtration units, they quickly became overwhelmed with contamination and the build-up of sediment.

With contaminated oil still passing through the grinding machines, the quality of the grinding process was compromised. Machine operators had to clean out the filters manually, resulting in machine downtime and labour costs. The collection of contamination in the grinding machines also affected the bellow machine covers in use on the Walter, resulting in their frequent replacement at a cost of approximately £3000 per year.

The swarf material that was removed from the machine was saturated with oil, which OSL Cutting Technologies had to pay to have removed and disposed of.

Solution

Eclipse Magnetics provided OSL Cutting Technologies with an AutoMag Skid magnetic filtration system. The AutoMag Skid is an effective self-contained filtration and fluid recovery system with fully automated operation, minimising fluid loss during cleaning and ideal for the company’s tool grinding machines.

The AutoMag Skid removes magnetic and para-magnetic contamination, down to submicron size, from the oil used in OSL Cutting Technologies’ Walter grinding machine. The filter holds the contamination until it is released during the automated 'purge' process, which briefly diverts the filter's purged output so that fluid carries all the contamination to the buffer tank. The buffer tank then feeds the contaminated fluid to the high-intensity coolant roller, and the magnetic coolant roller removes the contamination from the fluid. The clean fluid is then put back into circulation, and the contamination is extracted in a form ready for disposal or recycling.

   

Since the installation of the AutoMag Skid magnetic filter from Eclipse Magnetics, approximately 90% of swarf material has been successfully removed from the oil. Cleaner oil means that it can be used for longer periods of time, therefore reducing costs. The effective removal of swarf from the oil results in extended lifespan of machine components, including bellows, saving OSL Cutting Technologies £3000 per year. Cost savings are also made regarding man power, as operators no longer have to clean out the filters manually.

The filter has also reduced the disposal costs of particulate removed from the oil. Previously, OSL Cutting Technologies had to pay for the disposal of a thick, oily paste which carried the metal particulate. The metal particulate removed by the AutoMag skid is much drier with substantially reduced oil content, and can, therefore, be sold as scrap.

Comment

David Hukin, Works Engineer at OSL Cutting Technologies said: “The AutoMag skid has exceeded our expectations; we are more than happy with its performance. 90% of swarf material is now being successfully removed from the oil, which is a massive improvement and results in plenty of cost savings for us.”

"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."

Adrian Seeley, Production Supervisor at AB MAURI UK & Ireland

"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"

Maintenance Manager at EXL Tube (Steel Ventures)

"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."

John Smith, MMTCI

"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."

Facilities Manager, Milacron Machines (Sub-Contract Machining)

"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."

Pat Richards, Chief Engineer at Simpsons Malt

“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”
