We are YINGLOING (HEROHOME) SUPERHARD MATERIALS MANUFACTOR which is a professional supplier of blades and grinding wheels. For Blades, today, we would like to share some material about common slitter knife which is specifically used to cutting corrugated board and paper.
The specific material of the can be divided into the following four kinds: Tungsten Carbide (TC), High-speed steel (HSS), Cr12mov (D2), 9CrSi.
Tungsten Carbide is an alloy material for cutting cast iron, nonferrous metals, glass, stone and ordinary steel, etc., can also be used to cut heat-resistant steel, stainless steel, tool steel and other difficult materials, it has high hardness, Grinding, high strength and toughness, corrosion resistance and a series of excellent performance, but because of its high prices, Most manufacturers will prefer high-speed steel, the premise is to keep the blade in the case of good cutting.
High-speed steel is a high hardness, high wear resistance and high heat resistance of the tool steel, high-speed steel process performance, strength and toughness with good, so mainly used to make metal cutting tools.
Cr12mov (D2) is also a kind of Hardened steel, but its performance is slightly worse than high-speed steel, because of its low price, so for ordinary cutting, it will usually choose this material.
9CrSi is a commonly used low alloy tool steel, with high hardenability and hardenability and high tempering stability, can be used for low-speed cutting tools.
The four materials applicable to the scope and use of slightly different, so to choose the right material, in order to achieve good cutting effect. The generally trends of price and using life about this four raw materials:
In the tissue paper industry, the application of the cutting knife, the above four kinds of materials can be used to. But the specific use of what kind of material need to see the type of cutting knife, For example, punching knife suitable for the use of 9CrSi material, a small round knife suitable for high-speed steel material, these are suitable for the material is to maintain a good use of the effect, the most cost-effective.
In the corrugated industry, the use of slitter knife, the most commonly used is the Tungsten carbide and high-speed steel material.
