Why do inline cutters & granulators need regular sharpening?
In order to cut properly, the cutting clearance between the bed and fly knives must be less than the thickness of the material you are cutting.
Over time, your blades will dull. When the knives are worn down so that the cutting clearance is equal or greater than the material thickness, they must be re-sharpened and adjusted to the original cutting clearance.
Uncut material traveling through a dulled inline cutter system will wrap around your rotors and stop your production line. It will also shorten the life of your bearings.
It is also imperative that cutting clearance across the width of the cutter is uniform in order to avoid intermittent cuts that lead to long strands of uncut material. Irregularly shaped trim waste clogs up systems and stops production lines.
The wear life of your blades is determined by the materials they're cutting. The most abrasive fiberglass, for instance, will erode your knives much faster than paper. Depending on your materials, blades may need to be sharpened as frequently as every 3 weeks or as rarely as once a year.
