Pre-coat filtration plant for honing and grinding

An Apperley Honing product story

The Apperley F012D Filter plant is aimed at medium- to high-output honing, grinding and spark erosion operators, giving a continuous filtration process as an alternative to paper band filters

The UK's leading independent contract honing specialist, Apperley Honing, has launched its pre-coat filtration plant to the precision engineering market.

Designed to eradicate the loss of precision associated with the build-up of honing and grind-up sludge in cutting oil, the new filter plant overcomes the shortcomings of the majority of incumbent filtration systems by combining speed and precision without impacting on cost.

Charles Sanders, Managing Director, commented: "Using a consistent supply of clean cutting oil eliminates the variable that dirty oil introduces to honing, grinding and spark erosion processes.

The net result is more control and thus greater speed and precision in achieving desired finishes." The Apperley F012D Filter plant is particularly aimed at medium- to high-output honing, grinding and spark erosion operators.

It provides users with a continuous filtration process that is the perfect alternative to paper band filters, which although relatively inexpensive have a tendency to be unreliable; and the more costly and disruptive centrifuge methods.

The machine has been developed to filter particles down to 3æm in size.

Sanders continued: "With hands-on knowledge of running a large honing operation, we've been in the ideal position to deliver a solution that provides a cost-effective alternative that will help companies circumvent the problems of 'dirty' cutting oil." Established in 1963, and now a leader in its field, Apperley Honing itself runs a large subcontract honing operation with 20 varieties of honing machine that can hone diameters from 3mm to 750mm, in lengths of up to 15 metres.

The F012D filter plant is designed to optimise plant performance.

It is linked to scavenge tanks and pumps fitted to machinery on the shop floor to provide an uninterrupted supply of clean oil.

As it is more efficient than the paper band/settlement tank system, and does not dictate the downtime of centrifuges, it is perfect for high capacity operations - particularly when running shift systems - and is especially beneficial for round the clock shifts.

Using diatomaceous earth, as the filter medium, coated to 12 polyester meshes, the F012D is extremely efficient in terms of the cost of consumables, low maintenance and reduced downtime.

Sanders added: "There are many companies that do not use filtration methods - but this is at the expense of wear and tear on machinery as well as the aforementioned loss of precision and control.".
