News & Innovations

Kronos, the intelligent cutting rotor

The best example of Schönenberger´s problem-solving expertise and innovativeness in the field of plastics is the Kronos cutting rotor, a world first. This cutting rotor is already considered to be a technological benchmark and is a credit its namesake, Cronus of Greek mythology. “This innovation is one of a kind. Kronos is based on joining the cutting rotor knife, made for example of tungsten carbide, with the rotor body. The cutting rotor knives are inserted into specially cut form-fit mounting slots without the use of any clamping devices or screws. As a result the rotor remains completely stress-free, an essential condition for a precision cutting and long tool life,”. The wedge shape of the cutting rotor knifes means that it is not weakenend even after severals resharpening cycles. In the past, resharpening always cost a lot of time and, in the worst case, resulted in machine downtime, but Schönenberger is pleased to announce that this is now a thing of the past. 

“We support the entire tool life cycle – from initial process consulting to the grinding process – directly from the production site in Deizisau near Stuttgart. “We call it “product- and life-cycle-management”.
