The sharp effect of the cutter of the program-controlled paper cutter and the service life can greatly affect the production efficiency of this paper cutter. The life and effect of a knife depend on several factors, such as the material of the knife, the shape and angle of the knife, the quality of the knife, and the type of material being cut.
        In the material of knife making, the material of the blade should be relatively high hardness chromium tungsten manganese steel, and the blade body can be made of low carbon steel. If it is a high-quality blade, it can reach a certain hardness after being subjected to a fire extraction process.
        In the shape and angle of the sharpening knife, if the angle of the sharpening edge on the knife is relatively small, its blade edge will be sharper. Therefore, as far as the cutting tool material allows, the sharpening angle should be as small as possible.

        The quality of the sharpening knife mainly depends on the technical level of the operator. If you feel the quality is higher, the longer it can be used.
