The Main Factors Affecting the Life of the Paper Cutter Blades

1. The material of the knife

The single-chip cutting machine tool is made by inlay welding of the blade and the cutter body at high temperature. The chromium tungsten manganese steel blade has a high hardness, low carbon steel blade body. The hardness of the tool steel of the durable blade is proportional to the quality of the blade, the blade hardness is as high as 60, and the quenching is HR55.

2. The quality of the paper cutter sharpening

The higher the quality of the paper cutter sharpening, the better the effect on the object and the longer the service life of the cutter.

3. The shape and angle of the sharpening.

Single-sided paper cutters generally use a single sharpening knife with a sharpening angle of 19° to 23°. Sharpening such a shape makes the inclined surface of the tool to withstand the pressure during the cutting process, which is cut from the part of the paper stack. The paper base in a section is rubbed, and the inclined surface of the blade is quickly worn. The cutting edge of the double-sided tool has obvious advantages, which helps to reduce the load of the machine and improve the accuracy of crop sharpening. Therefore, the sharpening angle should be as small as possible under the condition that the tool material allows and considering the size of crop resistance to shear.

4. Different crop materials.

The speed at which the edge of the reamer becomes dull is related to the cutting of abrasion-resistant materials during the cutting process. When cutting paper, the speed at which the blade becomes dull is related to the softness, hardness, and ash content of the paper. The hand feels during the cutting operation is harder. The harder the hand feels during the cutting operation and the greater the ash content of the paper, the faster the blade becomes dull.

Therefore, the use of various high-end automatic paper cutters, CNC paper cutters, and program-controlled paper cutter knives need to focus on skills, thereby improving the efficiency and service life of the paper cutter blades.
