Magnetic filters ensure clean cutting
oils
Installing one of the latest magnetic filters on a tool and cutter grinding machine ensures that the cutting oil is suitably filtered prior to it being reintroduced into the grinding operation.
Eclipse Magnetics recently installed one of its latest magnetic filters on a Walter 5-axis tool and cutter grinding machine at Elite Tooling in Rotherham Elite Tooling specialise in the manufacture of standard and bespoke solid carbide slot, end mill and form tools

Magnetics filter out ferrous debris to up quality
An automatic, self-purging filter removes every particle of magnetic debris to improve the quality, efficiency and economic performance of machine shop, grinding and finishing processes.
Magnetic filter improves machining quality
What is claimed to be the best magnetic filter on the market avoids re-circulating magnetic particles in any machine tool especially precision grinding applications.
One of the main difficulties when grinding Carbide is ensuring that the cutting oil is suitably filtered prior to it being reintroduced into the grinding operation at the cutting face.
Re-circulating contaminated oil can reduce surface finish quality, produce inconsistent parts, result in oil degradation and above all reduce an expensive machine tool into a tired looking and worn piece of critical equipment within months.
Bob Hill, Production Director at Elite Tooling states: "The recently installed Walter Helitronic Power Grinder enables various Carbide cutting tools to be machined from stock bar".

Magnetic chucks offer high work holding power
A high-performance, electro-permanent magnetic chuck offers 150 tonf/m2 of magnetic pull, enabling huge holding forces to be generated on even modestly sized workpieces.
"This includes the flute shaping operation, which generates the most contamination".
"Producing the final cutting edge is an extremely accurate operation, the last thing you need to be thinking about at this stage is whether or not the suspended particles in the cutting oil is going to effect the finished tool".
" At the time, the filter medium we were using was not really up to the job of removing the carbide particles".
"The first sign we recognised that this was happening was when the particles started to lay down on the top of flat surfaces making the machine look as if it had been working flat out for the last few years".
"It was at this stage that we realised that we needed to protect our biggest investment and decided to approach Eclipse Magnetics knowing that the particles were magnetic".
" After a brief discussion and visit by one of the Eclipse engineers we decided that we had to have a Filtramag unit".
"The filter was installed by Walter GB and has surpassed our original expectations".
"I would recommend the Filtramag to any company who grinds or hones component parts." The Filtramag benefits from the incorporation of six high intensity rod magnets, which incorporate Rare Earth magnetic material.
Utilising pole concentrators and proven magnetic circuit geometry the rods generate controlled, deep reaching magnetic flux fields, which produce a staggering 11,000 Gauss.
These flux fields attract and retain any magnetic particles that are suspended in the fluid.
The Filtramag offers unrivalled levels of both magnetic performance and contamination removal efficiency compared to more conventional designs.
Once purchased Filtramag requires no consumables resulting in less fluid loss and reduced impact to the environment.
The main benefits of using Filtramag compared to cartridge type filters are: * No running costs.
* No maintenance costs.
* No downtime associated with changing filter media.
* No loss of fluid due to replacing sodden cartridges.
*No back pressure, even when the magnetic cores are totally saturated with contamination.
* No mess.
Because Filtramag attracts even sub micron sized particles this extends the useful life of the fluid.
Units are available with port connection sizes of 3/4in, 1in, 1.1/2in and 2in diameter.
