Selection of the material for paper cutter blades
The paper cutter blades are produced using forged materials, making the blade edges sharp and durable. The blades can be produced according to the user's requirements. The main material of this type of blade is high-speed steel (sharp steel), and there are two types: the whole high-speed steel blade and the inlaid high-speed steel blade.
Whole high-speed steel: The whole blade is high-speed steel (sharp steel) HSS. The blade of this material has a relatively sharp edge, and the surface finish of the blade body is high and not easy to rust.
Inlaid high-speed steel: The blade edge is inlaid and welded high-speed steel (sharp steel), and the blade body is carbon structural steel. This kind of blade has a sharp edge, stable steel performance, and the whole blade body is not easy to break. Precautions: The blade body is prone to rust, and the blade should be kept clean after operation.
Rolling high-speed steel: The high-speed steel is accurately rolled at high temperature in the furnace onto the blade sheet matrix with the pre-opened grooves. The advantages are high density, not easy to fall off, more refined original grains, and strong resistance to chipping. There are no transitions or voids and other defects in the combination of high-speed steel and the matrix, and the blade edge has no peeling off. The service life and surface appearance degree are more superior than those of inlaid steel blades. (This high-density welding technique will be much superior to ordinary welding. For the same material, the blades produced by this process have a longer life and are less likely to fall off.)
The above are the three main processes to distinguish high-speed steel. However, the distinction of different types of high-speed steel will also lead to different blade costs, thereby resulting in different blade life, sharpness, and cutting effect. Blades select different grades of high-speed steel (W3, W4, 6542, W18Cr4V, M2, M35, M42, SKH-9, SKH-51) and other domestic and foreign high-speed steels for production according to different cutting methods and cutting products, and the hardness can reach up to 67°.
In addition, for some special products, we have also carried out the manufacturing process of whole tungsten steel or inlaid tungsten steel. This process makes the tool life more durable, and generally, it will be several times the life of high-speed steel products under normal procedures.
