Advantages and disadvantages:
1. The domestic standard brand of tungsten-cobalt cemented carbide is YG, but now almost all the products of better manufacturers are not standard brands, but only their own brands and international standard usage codes. The code name for cutting cast iron is K.
According to international standards, K05 has good wear resistance, that is, it is the hardest and easy to crack, while K50 has poor wear resistance and is not easy to crack. But now international standards add symbols before this K to represent the types of materials, such as HW for uncoated cemented carbide and HC for coated cemented carbide.
2. Cutting cast iron with silicon nitride ceramics is usually more efficient than cutting cast iron with cemented carbide.
3. Generally speaking, cubic boron nitride (CBN or PCBN) can obtain the highest efficiency, but the blade is expensive.

Blade types and uses
1, toothed blade
Toothed blade
Toothed blades are made of high quality materials, sharp and durable, and rust-proof. Their advantages are no burr cutting, long service life, higher production efficiency for your machine, tooth pocket cutting, beautiful lace and easy tearing.
Main uses: cutter of throwing machine, cutter of bag making machine, cutter of sealing machine, cutter of adhesive tape, cutter of rotary printing machine, cutter of filling and packaging machine, cutter of measuring and packaging machine, cutter of food filling and packaging machine, cutter of outer packaging machine, cutter of chemical machinery, cutter of drug packaging machine, etc.
2. Cutting blade
Mainly used for cutting paper, film, gold foil, silver foil, copper foil, aluminum foil, tape and other items. It is required that the cutting resistance of the blade is minimum and the wear resistance is maximum. In order to meet the requirements of commodity precision, the blade must reach micron precision, and the materials are selected: 9CrSi, Cr 12Mov, W6Mo5CrV2, W 18Cr4V, etc.
3. Longitudinal scissors
It can be used in the following industries: large steel mills, steel pipe factories, nonferrous metal processing plants, strapping material factories, cold rolling plants, packaging materials factories, steel plate processing service centers, steel mesh factories, strip rolling mills and slitter manufacturers. For the requirement of high precision, the thickness tolerance can now be guaranteed to reach 0.0005 mm. For a small circle, its tolerance can reach H3.
4, dotted blade
These are strip and round blades for punching and virtual wire cutting, food packaging, medical packaging and other businesses, as well as folding machine blades, sealing and cutting blades. Materials: 9CrSi, Cr 12MoV, W6Mo5CrV2, W 18Cr4V, etc.
5. Leather blades
Leather blade is mainly used for cutting all kinds of leather, with neat incision and no burr, which is convenient for processing all kinds of leather products. Materials: 9CrSi, Cr 12MoV, W6Mo5CrV2, W 18Cr4V, etc.
6, rubber mechanical blade
Rubber mechanical blades are generally special-shaped blades, mainly including various tooth-shaped flat circular knives and strip knives. Materials: 9CrSi, Cr 12MoV, W6Mo5CrV2, W 18Cr4V, etc.
7, metallurgical blade
Cold bonding shear tools: In cold bonding, we use many medium and high alloy tool steels and heavy powder metallurgy steels as the basic materials of crosscutting tools, and the crosscutting tools made from them can cut: crush all kinds of cold bonded thin plates, medium and wide plates, hydraulic shear and flying shear of all kinds of steel plate wastes.
Hot-rolling shear tools: In hot rolling, we use many high-quality steel materials as cross-cutting tools, such as cross-cutting tools made of alloy steel, which can cut: hot-rolled steel, thick steel plate, ingot tail, steel bar, round steel and so on.
8, pipe cutting blade
This is a tool mainly used in pipe production line, which moves synchronously with the speed of pipes (including paper pipes, copper pipes, aluminum pipes, steel pipes, etc.). ). While rotating along the periphery of the pipe, slowly cut into the center to cut the pipe. Materials: 9CrSi, Cr 12MoV, W6Mo5CrV2, W 18Cr4V, cemented carbide, etc.
