ATK system for grinding circular blades

ATK, system for grinding circular blades on linear sharpening machine

The system ATK is an innovative, revolutionary and unique grinding machine, that is able to combine into a single professional machine the capability of sharpening both straight and circular blades.
This innovation is made possible by using the ATK system, that has been patented by MVM in 2014, that features a motorized rotary axis that is adjustable from 0° to 60°, for sharpening circular blades and counter-blades up to max Ø 300 mm. This new system can be mounted on our linear grinding machine models KS250, KX250, FX20 and FX40.

This new unique hybrid grinding machine allows the re-grinding of two very different types machine blade, therefore maximizing production efficiency and increasing the investment return on the machine purchase.
This application is suitable and recommended for professional grinding centers and for the tissue industry and paper mills.
