Reasons For Affecting The Effectiveness Of Cutting Machine Blades

What are the reasons that affect the effectiveness of cutting machine blades? How can the correct use of pneumatic slitting machines, corrugated cardboard slitting machines, and metal slitting machines improve the efficiency and lifespan of blade usage?
The cutting material is a key factor in determining the durability of the cutting machine blades; For ordinary cutting blades such as paper, plastic, and film, SKD-11 alloy steel with higher chromium content should be selected; High speed cutting machine blades need to have high wear resistance, so high-speed steel is the best cutting material;
In general, the durability of the blade is directly proportional to the heat treatment hardness; Therefore, high-quality cutting machine blades can have a hardness of HR55~60 after quenching treatment, while blades made of high-speed steel materials still require vacuum heat treatment to achieve ideal hardness and toughness.
The grinding accuracy and blade angle of the blade are also one of the factors that affect its lifespan. The cutting machine blade generally adopts a single blade design, with a grinding angle of around 30 °. Usually, the inclined surface of the cutting edge bears a relatively large amount of friction during the cutting process. Under the friction of the paper edge, the inclined surface of the blade is quickly worn out. Considering the shear resistance of the cutting object, the angle of grinding the blade should be as small as possible.
When selecting blades, the texture of the cutting material should be taken into account; The speed at which the blade becomes blunt during the cutting process is related to the wear resistance of the material being cut. When cutting materials with harder texture and greater toughness, the selected cutting machine blade should have better texture and hardness.
The cutting machine blade is a specialized blade used in the printing and packaging industries, and the cutting accuracy, sharpness, and service life greatly affect the production efficiency of the product; Reasonable selection and selection of cutting machine blades can better increase the production efficiency of finished products and shorten the cutting time.
