The sharpness and durability of a paper cutter blade directly impact cutting efficiency. Metal material and a precise grind angle (∠19°-23°) are key. High-speed steel blades can last up to five times longer than ordinary blades. Paper hardness and ash content accelerate blunting. Choosing the right specifications (such as 400×127×12.7) can significantly improve cutting quality and blade life.
- The Importance of Paper Cutter Blades
Paper cutter blades, as core components of paper cutters, play a vital role in the papermaking and printing industries. Whether manual, electric, automatic, or CNC paper cutters, or even those designed specifically for toilet or household paper, they all rely on the blade’s precise cutting. The blade’s sharpness and durability directly determine the efficiency of the paper cutter.
As an indispensable core component in the papermaking and printing industries, the sharpness and durability of paper cutter blades have a profound impact on paper cutter efficiency. Metal blades play a vital role in all types of paper cutters, ensuring precise cutting, whether manual, electric, automatic, or CNC.
The Importance of Metal Material: Metal material is crucial to the sharpness and durability of paper cutter blades, impacting the efficiency of the machine.
The Blade Dependencies of Different Paper Cutter Types: Different paper cutters rely on blades with different characteristics to ensure efficient operation.
- Use and Maintenance of Paper Cutter Blades
Blade Material and Heat Treatment
Single-piece paper cutter blades are constructed by high-temperature welding of the blade and blade body. The blade is made of high-speed steel, while the blade body is made of low-carbon steel. The choice of material has a crucial impact on the blade’s hardness and durability. After heat treatment, high-quality blades can achieve a hardness of HRC 58-60.
Grinding Angle and Finish
For single-sided paper cutter blades, the grinding angle is typically set between ∠19° and ∠23°. This design allows the blade’s beveled surface to withstand the pressure of paper edges during cutting. However, this also leads to more susceptible blade wear. Double-edged blades, by contrast, offer greater wear resistance. Their ground edge design reduces the load on the paper cutter while improving paper cutting accuracy. To extend blade life, the grinding angle should be kept within a range of ∠19° to 23°, provided the blade material is high quality and the paper has moderate cutting resistance.
The Impact of the Grinding Angle of a Paper Cutter Blade on Wear Resistance: The choice of edge angle is crucial to blade durability and cutting accuracy.
The Impact of Surface Finish on Cutting Resistance and Life: When grinding a paper cutter blade, the surface finish is crucial. A higher finish means a smoother blade, which reduces resistance during cutting, extending blade life and improving cut quality.
The Impact of Paper Type on Blades: During paper cutter use, the hardness or softness of the paper directly affects the rate at which the blade wears down. Especially when cutting hard paper with a high ash content, such as high-gram coated paper, the blade will dull significantly faster. Therefore, the hardness and ash content of the paper will affect the blade’s dulling rate. Understanding and selecting the appropriate cutting techniques can extend blade life.
Paper Cutter Blade Types and Specifications
Alloy and High-Speed Tool Steel Blades
Features of Alloy Tool Steel and High-Speed Tool Steel: These blades utilize a composite rolling process and are suitable for general cutting needs. Their original grain undergoes special treatment, significantly improving chipping resistance. High-Speed Tool Steel Paper Cutter Blades are widely suitable for various papers, especially high-gram coated paper, and offer a lifespan five times that of standard blades between sharpenings.
Applications and Advantages of Each Blade: Alloy Tool Steel and High-Speed Tool Steel blades are suitable for cutting general and high-gram paper, respectively. Their dimensions and finish provide excellent wear resistance.
