Coolant filtration is a value-adding factor in tool grinding

March 24, 2023 - 08:00am

In tool grinding, all influencing parameters in the overall cutting chain must be perfectly coordinated. Cleaned coolants and lubricants are essential pieces in the mosaic.

At the GrindTec 2023 show in Leipzig, Germany, in early March, the filtration specialist Vomat in Treuen, Germany. showcased high-performance ultrafine filtration technology that the company says shows how tool manufacturers can realize high quality and economic efficiency with optimally filtered coolants.

In tool grinding, coolants are on the one hand a cost factor and on the other hand an important quality-determining parameter, and the longer the cleaned coolant can remain in the system, the less coolant it requires, storage and recycling costs are reduced, and the grinding wheels also do not have to be changed or dressed as often. 

Steffen Strobel, technical sales manager at Vomat, said, "Vomat FA filtration systems are ideal for filtration of ultra-fine particles from grinding oils. Important features include full-flow filtration with 100 percent separation of dirty and clean oil, on-demand filtration and backwashing of the high-performance precoat filters, and high-precision temperature accuracy."

On the standard platform of the FA machine series, individually tailored concepts - from small-scale systems to industrial central filtration solutions - can be configured thanks to a wide range of optional add-on modules.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
