Paper Core Cutting Machine Blade
The paper tube machine blade is a round blade with an outer diameter of 28-610 mm and a thickness of 0.3-80 mm. It has a sharp edge, high hardness, and good toughness.
Our paper tube machine blades are made of high-carbon steel, high-speed steel, tool steel, alloy steel, stainless steel, 65Mn, and 9CrSi.Cr12MoV, SKD-11, SKH-51, 3Cr13, 9Cr18, SUS440C, 420J2, W6Mo5Cr4V2, etc.
① Small knife-edge single layer: This is currently more commonly used. Mainly used for cutting hard or thick materials. Such as stickers, paper, leather, plastic, etc.;
②Large knife-edge double layer: This kind of knife-edge slope is relatively large, so the cutting resistance is small and the incision is smooth.
It is mainly used for cutting thinner materials with higher requirements, such as film, thin plastic, etc.
Our paper tube machine mainly uses a single-layer knife edge with a small knife edge, which is carefully polished to create a sharp edge, and the blade edge is sharp to ensure that the paper tube after slitting has no burrs and the surface is as smooth as a mirror.
