The paper cutter is an essential tool in paper mills, therefore it is used in industries such as papermaking and printing. The sharpness and service life of the blade greatly affect the efficiency of the paper cutter. Next, I will briefly introduce the product to you, hoping to bring you some help.
The effectiveness and lifespan of paper cutting machine blades. When using automatic paper cutting machines, CNC paper cutting machines, programmable paper cutting machines, and other paper cutting machines, paying attention to work skills can improve the efficiency and lifespan of paper cutting machine blades.
- Cutting material for paper cutter blades
The blade of a single piece paper cutter is made of high-temperature welding between the blade and the blade body, with the blade made of high-speed steel and the blade body made of low-carbon steel. The hardness of the blade of a paper cutter determines its durability. High quality paper cutter blades have a hardness of HRC58~60 after heat treatment. - Grinding angle of paper cutter blade
The single-sided paper cutter blade is a single edged blade with a grinding angle of ∠ 19 °~23 °. The grinding edge of this shape causes the angled surface of the blade to bear the pressure of the paper edges during cutting, and the blade edge is quickly worn out. The double-sided blade has good wear resistance, and grinding the edge can reduce the load of the paper cutter and improve the accuracy of paper cutting. When the material of the paper cutter blade is excellent, considering the cutting resistance of the paper, the angle of the grinding edge should be as small as ∠ 19 °~23 ° as possible. - Quality of paper cutter blade grinding
When grinding the blade, the higher the smoothness of the grinding, the lower the cutting resistance, the longer the service life of the paper cutter blade, and the better the cutting quality. - The type of paper cut by the paper cutter
In the cutting process of a paper cutter, the speed at which the blade edge of the cutter becomes dull is relat
