3 Minutes to Understand Paper Cutting Blades

(1) The material of the cutter blade

The single-piece paper cutter blades are made of high-temperature inlaid welding of the blade and the blade. The blade is made of high-speed steel and the blade is made of low-carbon steel. The hardness of the cutting edge of the paper cutting blades determines the durability. The high-quality paper cutter blade has a hardness of HRC58~60 after heat treatment.

 

(2) The grinding angle of the paper cutter blades

 The single-sided paper cutting blade is a single-edged blade, and the blade grinding angle is ∠19°~23°. The grinding edge of this shape makes the bevel surface of the blade bear the pressure of the paper corner during cutting, and the blade's edge is quickly worn.

 

The double-sided blade has good wear resistance, and the grinding edge can reduce the load of the paper cutter and improve the accuracy of paper cutting. When the material of the paper cutter blades are excellent, considering the cutting resistance of the paper, the angle of the grinding edge should be less than ∠19°~23°.

 

(3) The grinding quality of the paper cutting blades

 When grinding the blade, the higher the grinding finish, the lower the cutting resistance, the longer the service life of the paper cutter blade, and the better the cutting quality.

 

(4) The type of paper cut by the paper cutter

 In the cutting work of the paper cutter, the speed of the cutting edge of the paper cutter blade is related to the hardness of the paper being cut. When the paper cutter cuts the paper with hard paper texture and high ash content, the blade passivation is fast, especially when cutting various high-gram coated papers.

 

(5) Matters needing attention

The use effect and life of paper cutting blades. When using automatic paper cutters, CNC paper cutters, program-controlled paper cutters, and other paper cutters, pay attention to working skills to improve the efficiency and service life of the paper cutter blades.
