What are the factors that affect the service effect and life of the paper cutter blade Release time：2020-08-12　　　　 Time to browse

　　Slitting blade

　　1. The shape and Angle of the knife on the paper cutter. In the single-side paper cutting machine, generally use a single-edge cutter, its edge Angle between 19°~23°. However, this shape of the edge makes the bevel face of the cutter bear the pressure from the paper stack that has been cut off during cutting. Under the friction of the edge of the paper, the inclined face of the blade is quickly worn away. The double edge cutting tool has obvious advantages, its sharpening helps to reduce the load of the machine, and improve the cutting accuracy. Therefore, the Angle of the sharpening edge should be as small as possible under the condition that the tool material allows and considering the size of the shear resistance of the cutting object.

　　2. Knife making materials. The cutting tool of the single chip paper cutter is made of the blade and the blade body are welded by high temperature. The blade is made of chromium-tungsten-Manganese steel with high hardness and the cutter body is made of low carbon steel. The durability of the cutter is directly proportional to the hardness of the steel used on the blade. The hardness of the blade with high quality after quenching treatment can reach HR55~60.

　　3, cut the type of material. In the process of cutting, cutting machine edge blunt speed and the material cut by the abrasion resistance. When cutting paper, the blade blunt speed and the paper's hard and soft texture and how much ash content. The harder the texture, the greater the ash content of the paper, the blunt blade faster.

　　4. The quality of the knife on the paper cutter. The higher the quality of the sharpening knife, the longer the service life of the cutting knife, the better the cutting quality.
