1. Material of knife making.
        The cutter of the single-piece paper cutter is made of high-temperature insert welding of the blade and the blade body. The blade is made of high hardness chromium tungsten manganese steel, and the blade body is made of low carbon steel. The durability of the cutter is directly proportional to the hardness of the steel used for the blade part. For high-quality blades, the hardness of the blade part after quenching can reach HR55 ~ 60.
        Second, the shape and angle of the sharpener of the paper cutter.
        On single-sided paper cutters, single-edged cutters are generally used, with a sharpening angle between 19 ° and 23 °. However, the sharp edges of this shape make the bevel of the cutter bear the pressure from the part of the paper stack being cut during the cutting process. Under the friction of the paper edge, the bevel of the blade is quickly worn away. The double-edged knife has obvious advantages. Its sharpening helps to reduce the load of the machine and improve the accuracy of cutting. Therefore, the angle of the sharpening edge should be as small as possible when the tool material permits, and considering the magnitude of the shear resistance of the cut object.
        3. The quality of paper cutter sharpening.
        The higher the quality of the sharpening knife, the longer the service life of the cutting knife, the better the cutting quality.
        4. Types of cutting materials.
        During the cutting process, the speed at which the cutter edge of the paper cutter becomes blunt is related to the wear resistance of the cut material. When cutting paper, the speed at which the blade becomes dull is related to the texture of the paper and how much the ash content is. When cutting harder paper with a larger ash content, the faster the blade becomes dull.

        First, the hydraulic paper cutter cuts text of different materials, and the processing speed is relatively fast. And it can ensure that the cut material has a certain accuracy after being cut. When cutting a larger density cut material, the difference between it and the ordinary paper cutter is particularly obvious. Customers who have high requirements for cutting precision You can choose it.
        The double hydraulic computer paper cutter is a kind of equipment controlled by a microcomputer program. The pressure of the paper pressing can be set by the computer, and the actions of pushing paper, pressing paper, and cutting can be automatically completed. The specially designed knife lock can also effectively prevent the phenomenon of sliding knife.

        The paper cutter is the standard supporting mechanical equipment of the printing factory, which is mainly used to deal with the paper cutting needs in the early and late printing.
        The paper cutter is developed from the original mechanical paper cutter to the tape control room paper cutter, and then to the microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting. External programming and editing of production data. The system makes the production time of the paper cutter shorter, the cutting precision is higher, the labor intensity is lower, and the operation safety is better.
        The current paper cutters are roughly divided into three categories, including manual paper cutters, electric paper cutters and hydraulic paper cutters.
        The manual paper cutter is the most traditional paper cutter, also called a cutting knife, and the paper cutting size is small, generally used for simple text cutting processing;
        The electric paper cutter is controlled by a pure mechanical structure to control the operation of the cutter, which is convenient for cutting and suitable for batch processing of documents;
        The hydraulic paper cutter contains hydraulic oil in its internal structure. The operation of the hydraulic oil is used to control the operation of the cutter. Because the electric paper cutter may cut through some soft papers, it may not be cut through. Paper processing industry. The hydraulic paper cutter can cut rice, leather, paper and other materials, and the processing speed is fast, so it is widely used in libraries, printing and publishing.

        In the use of paper cutter blades and slitter blades, the pollution of noise, exhaust gas, waste, etc. is still the main factor that damages the environment.
        We should abandon this kind of paper cutter blade, the traditional harmful production mode of slitting knife, and continue to explore the emerging sustainable development of cutter blade, green production mode of slitting knife.
        For the design of paper cutter blades and slitter blades, a lot of manpower and material resources are generally required. In the manufacturing process of paper cutter blades, slitter blades and other mechanical blade products, not only a large amount of waste material is natural, but also because of slitting The lack of flexibility in the production of machine blades and slitting knives has resulted in serious lavish use of equipment resources.
        Especially after the cutter blades, slitter blades and equipment are damaged, they often become a huge waste of resources and at the same time, many toxic and harmful and unrecyclable slitter blade waste materials are harmful to the environment and the people who dominate the environment. It will also cause great harm.
        In this process, a large amount of pollutants such as exhaust gas, waste water and residual impurities enter the environment. The typical characteristic of the traditional production mode of the slitting knife is to obtain resources from the natural world and become various engineering materials after refining.

        Tips for replacing and using cutter blade of paper cutter:
        1. A blade can be used 8 times;
        2. If you find that the blade has been too deep, you need to adjust or replace the blade;
        3. The blade can be taken out with a screwdriver, and should be put into the cutting table smoothly when it is put back;
        4. The blade should be on the left side.
