(1) Materials for paper cutting machine blades

The integrated paper cutter blade is made of high-temperature embedded and welded blades and the main body. The blade is made of high-speed steel, and the blade is made of low-carbon steel. The hardness of the paper cutting blade determines its durability. A good paper cutter blade has undergone heat treatment and has a hardness of HRC58-60.

(2) Grinding angle of paper cutter blades

The single sided paper cutting blade is a single edged blade with a grinding angle of ∠ 19 °~23 °. This shape of edge grinding causes the inclined surface of the blade to withstand the pressure of the paper corner during the cutting process, and the blade wears out quickly.

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

(3) Grinding quality of paper cutting machine blades

When grinding the blade, the higher the grinding degree, 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 at which the paper cutter cuts the edges is related to the hardness of the paper cutter. Paper Cuttings. When the paper cutter cuts paper with hard paper texture and high ash content, the blade will quickly passivate, especially when cutting various types of high gram coated paper.
