There are currently two types of silicon paper sheeting machine in China: overall cross-cutting knives and inlaid cross-cutting knives.
The overall cross-cutting knife is stamped and formed using SKD11, CR12, 9CRSI and other materials, and the heat treatment grinds the knife edge, HRC50-58 degrees, the material is not the same, the hardness is the same, this blade generally has a low service life, and the knife edge is not sharp enough. Precision materials do not work well.
The inlaid cross-cutting knife refers to the cutting edge inlaid with high-speed steel HSS, the blade body uses abrasive steel SKD11, and the heat treatment is used to grind the blade edge, HRC60-63 degrees, HRC is different for different high-speed steels. This blade generally has a high service life. Everyone knows high-speed Steel has high hardness and toughness, which is suitable for high-speed cutting. Even if cutting some high-precision materials, the cutting edge is smooth, without burrs, and durable.
