Carbide Large Diameter Rotary Shear Blades Tungsten Carbide Slitter Blades Disc Cutters
Application
The large diameter rotary shear blade is mainly used on tissue paper machines to cut rolled toilet paper, rolled embossed paper etc. During the cutting, the Friction between blade and paper generates heat, thus the blade edge is required to be sharp and wear-resistant, and the radiaL runout oF blade be small.
