Precautions for using Paper Slitter Machine to sharpen knives

The printing industry, packaging industry, and the use of paper cutters provide greater cutting accuracy. Automatic paper cutters, CNC paper cutters and program-controlled paper cutters are widely used in various high-end paper cutter related industries. The members of the blade cutter, its sharpness and the duration of use, and the degree of production efficiency of the paper cutter largely influence the use effect.

What are the main factors affecting the use effect and the life of Paper Slitter Machine blades?

First, the material of the knife. The single-chip cutting machine tool is made of inlaid welding between the blade and the blade body at high temperature. The chromium tungsten manganese steel blade has high hardness and low carbon steel blade body. Durability The hardness of the tool steel of the blade is proportional to the quality of the blade, and the blade hardness is as high as 60 quenched HR55.

Second, the quality of Paper Slitter Machine sharpening. The higher the quality of the brother, the longer the service life of the cutter and the better the quality of the crop.

Third, 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 bear 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, in the case of the tool material, the angle of sharpening should be as small as possible, taking into account the size of the crop's shear resistance.

Fourth, different crop materials. The speed at which the edges of the reamer become blunt and the cutting of abrasion-resistant materials during the cutting process. When cutting paper, the speed at which the blade becomes dull and the paper texture is soft, hard and ash content. The hand feel during the cutting operation is harder. The greater the ash content of the paper, the faster the blade becomes blunt.

Therefore, using various high-end automatic paper cutters, CNC paper cutters, and program-controlled paper cutter knives, pay attention to skills, thereby improving the efficiency and service life of the cutter blades.
