The use of printing, packaging, and paper cutting machines provides greater cutting accuracy. Automatic paper cutting machines, CNC paper cutting machines, and programmable paper cutting machines are widely used in various high-end paper cutting machine related industries. The composition, clarity, and usage time of blade cutters, as well as the production efficiency of paper cutting machines, largely determine their effectiveness in use.

What are the main factors that affect the lifespan of paper cutting machine blades?

Firstly, the material of the knife. The tool insertion welding of a single piece cutting machine is formed by the blade and blade body at high temperatures. The chromium tungsten manganese steel blade has high hardness and low-carbon steel blade body. The hardness of durable tool steel is directly proportional to the quality of the blade, and the hardness of the blade can reach up to 60 quenched HR 55.

Secondly, the quality of the sharpening knife in the paper cutting machine. The higher the quality of the brothers, the longer the service life of the cutting tools, and the better the quality of the crops.

Thirdly, the shape and angle of grinding. Single sided Paper Cuttings machines generally use a single sharpener with a grinding angle of 19 °~23 °. The shape of sharpening enables the pressure of the inclined cutter to be cut off from the paper stack during cutting, the paper base on one section to be rubbed, and the inclined plane of the blade to be worn quickly. The edge of double-sided cutting tools has obvious advantages, which are beneficial for reducing the load of machine tools and improving the accuracy of crop grinding. Therefore, in the case of cutting tool materials and considering the size of crop shear resistance, the sharpening angle should be as small as possible.

Fourthly, different crop materials. During the cutting process, the cutting speed and wear-resistant material at the edge of the winch. When cutting paper, the speed at which the blade becomes blunt and the softness, hardness, and ash content of the paper. The harder the handle of the cutting operation, the higher the ash content of the paper, and the slower the speed of the blades.

Therefore, various high-end automatic paper cutting machines, CNC paper cutting machines, and programmable paper cutting machine knives are adopted, emphasizing skills to improve the efficiency and service life of paper cutting machine blades.
