Circular Shear Slitter Blade For Slitting CR HR STEEL COILS
Flatness and Parallelism
Sufficiently high flatness and parallelism are necessary conditions to ensure that the shear clearance between the upper and lower slitter blades of the slitting machine is always consistent during dynamic operation. Correct clearance is at the heart of ensuring precision cutting. If the surfaces of circular slitter knives are not flat, or the blade's two sides are not parallel, the gap between the upper and lower blades is always changing. In addition, the reaction force generated by the extrusion of the strip during slitting also causes the gap to change continuously. This will make it impossible to get burr-free strips.
Thickness Tolerance
The thickness tolerance of the blade is mainly to ensure the cutting accuracy of the width of the metal strip and prevent the cumulative error in the knife assembly. If a blade with a thickness tolerance of 1~2 μm or even 0.5 μm cannot be provided, the cumulative error when multiple shearing knives are assembled is unavoidable.
Surface Roughness
Good surface roughness of the slitter knife surface can improve the rigidity of the entire shearing system, increase the sharpness of the blade, reduce micro-cracks on the blade and prolong the life of the blade. Different machining processes can result in different surface finishes. For high-precision non-ferrous metal processing, it is generally necessary to choose 0.05 - 0.1 μm. For slitting other thin coils, a surface roughness of 0.1 - 0.2 μm can be chosen.
