In the vast majority of precision slitting of metal sheets, the service life of the knife is not only related to the slitter knife itself, it also affects the service life of the rubber bonded ring. When the slitter knife becomes smaller because the knife is not sharp enough and it is re-sharpened many times, the outer diameter of the rubber stripper ring must also be synchronously reduced again and again. In the end, the outer diameter of the rubber stripper ring and the outer diameter of the iron core are getting closer and closer, and the rubber layer becomes thinner and eventually loses its elasticity and cannot work. This is the moment when the rubber stripper ring must be scrapped.
Under normal circumstances, when the outer circle of the knife is ground to 85% of the original outer diameter, it can no longer work. In order to prolong the service life of the entire set of tools, leaders and engineers in the sheet metal cutting industry must take a number of measures, such as confirming that one cutting edge should be used first, and then the other cutting edge should be used after the first edge is blunt. The user should try to buy a large number of slitter knives at once to avoid unnecessary multiple grinding of the rubber stripper ring. Comprehensive consideration, as far as possible to extend the service life of the entire set of tools.
