Paper cutter blade is one of the important parts of the paper cutter, widely used in the paper and printing industry. Paper cutter blades are used in papermaking, printing and other industries, the sharpness and service life of the blades, to a large extent, affect the efficiency of the paper cutter. Paper cutter blades are also known as paper cutter blades, paper cross-cutting blades, paper cutter blades, paper cross-cutting blades, full sheet paper cutter blades, but no matter how paper cutter blades are still a kind of straight knife.
The material of straight knife for paper cutter
Notes on the use of straight knives for paper cutters
There are two common materials used for straight knives for paper cutters on the market, one is alloy steel and the other is high-speed steel.
Alloy steel straight knife
The blades are compound rolled and can be used for general cutting. The original grain of the blade is finer and has high resistance to chipping. There is no transition and no gap and other defects in the combination of blade steel and knife body, and the blade edge is free from peeling, which can effectively ensure the service life of the blade.
High-speed steel straight knife
This material is suitable for cutting various kinds of paper, especially for cutting various kinds of high grammage coated paper, and the life of one sharpening can be increased by 5 times. High-speed steel contains 18% tungsten, which has the advantage of resistance to wear and tear. The blade is flat, sharp, and stable, and the cutting quality is precise and smooth.
When using automatic paper cutters, CNC paper cutters, program-controlled paper cutters, and other paper cutters, pay attention to work skills that can improve the efficiency and service life of paper cutter blades.
Paper cutter blade knifemaking materials
The single paper cutter blade is the blade and blade body high-temperature inlay welding, blade material for high-speed steel, blade body material for low carbon steel. The hardness of the blade of the paper cutter blade determines the durability of, a high-quality paper cutter blade, after heat treatment hardness HRC58 ~ 60.
Paper cutter blade grinding angle
The single-sided paper cutter blade is a single-edge blade, blade grinding angle in ∠ 19 ° ~ 23 °. This shape of the grinding edge makes the beveled side of the blade in cutting used to withstand the pressure of the paper edge, the blade's edge is quickly worn. The double-sided blade has good wear resistance and the ground edge reduces the cutter load and improves the accuracy of paper cutting. In the case of good material of the cutter blade, the angle of the ground edge should be less than ∠19°~23° as much as possible, considering the size of the cut paper resistance to cutting.
The quality of paper cutter blade grinding
When grinding the blade, the higher the grinding finish, the smaller the cutting resistance, the longer the service life of the paper cutter blade, the better the cutting quality.
Type of paper cut by paper cutter
In the paper cutter cutting work, the speed of dulling the blade of the paper cutter and cutting paper is soft and hard related. Paper cutting machine cutting paper hard texture, ash content of the paper, the blade blunt fast, especially cutting a variety of high-grain coated paper.
