All current CNC razor slitting machines allow for setting changes to the sharpening frequency and/ or sharpening duration. Excessive sharpening decreases blade life. By monitoring your slitting quality and making gradual changes to sharpening frequency and duration, you can work toward optimizing the life of your slitter blades. All too often we find that razor slitter sharpening is set for worst case running scenario and leads to excessive sharpening. Consult your operator’s manual or your service technician for specific machine adjustments.

Maintain a slitter blade sharpening log that includes board combination and optimal grind settings. This will aid in understanding your slitter machine and how to get the most out of each slitter blade.
