1. The blade that has just been sharpened is put into use, and when it does not encounter hard foreign objects in the cutting, it will suddenly collapse. Analysis: The main reason for this problem is the improper control of the cutting edge infeed during the grinding process (the infeed is too large), resulting in excessive temperature during the grinding process (that is, the temperature of the contact point between the blade and the grinding wheel is too high) To "burn out" the blade.
2. The cutter can't cut to the end when cutting (also called indigestion). Analysis: This is mainly due to the excessive straightness of the blade.
3. Immediately after the blade is sharpened, the cut surface of the cut paper product has knife flowers and poor cutting during the cutting process. The main reason is that the blade is too soft due to overheating. The grinding quality of the cutter is very important to the cutting quality.
