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.
Material DIN: 1.2379 (D2). Made from German heat-treated blanks, the problem of blade radial runout generated after heat treatment due to too large outer diameter and small thickness of blade is solved.
Hardness of Rockwell: 60-62
The common specifications are φ610×φ68.26×4.76, φ610×φ68.26×3.80, φ610×82.55×4.76, φ610×82.55×3.80. If you need blades of other sizes, please provide design drawings for us, and we will tailor the most suitable blades for you.
The outer diameter can be 1200mm.
