Paper cutting blades in the paper processing industry are sharp and durable, and the blades can be produced according to the requirements of users. The material of this type of blades is mainly high-speed steel, and there are two types of high-speed steel blades and high-speed steel inlaid. Sharp and stable, the cutting quality is accurate and smooth, suitable for all kinds of paper, especially for cutting various high-gram coated paper, the blades choose different grades of high-speed steel (W3, W4, 6542,W18Cr4V, M2, M35, M42, SKH-9, SKH-51) according to different cutting methods and cutting products to produce, the hardness can reach 67 HRC.Addition, for some special products, we also make integral tungsten carbide blades or inlaid tungsten carbide blades.This process makes the life of the tool more durable, and the life of the tungsten carbide blades product will be several times higher under the general procedure.
