Rolling Shear Blades Slitting Knives 1.Our blade description: (1)We manufacture rotary slitter knives up to 1300mm(51.1811 inches) in outside diamter for slitting metal plates, coils etc. (2)Knives are available with polished side faces ,High cost performance ,Punctual delivery . (3)Slitter knives are manufactured to a thickness tolerance of ±0.002mm-0.003mm(±0.00007 inch-±0.00012inch). (4)Parallelism tolerances is within 0.003mm (0.00012 inch) These are all prerequisites for the best possible slitting results. (5)Slitting knife blade used for slitting paper, plastic film, tape, aluminum, copper foil etc. 2.The main advantages of blades: (1) High hardness and wear resistance, meanwhile use hard material coating in line with application requirements and the coating can reduce friction to reach excellent cutting ability and low wear characteristics; (2) Sufficient strength and toughness to bear greater cutting force, and impact load and vibration; (3) Good heat resistance brings good processability, such as processing performance, forging performance, high-temperature plastic deformation and grinding performance. (4) Blades widely used in metallurgy, electronics, appliances, paper, packaging, printing, forestry, plastics, chemicals, food, textile and other industries.
