Problems solved by technology

[0002] When the circular cutting machine is working, it drives the material to rotate, so that the cutting knife of the circular cutting machine cuts the material into strips. Due to the long-term contact and friction between the cutting knife and the material, the strength and wear resistance of the cutting knife are poor. , it is easy to cause the cutter to curl and break, which will affect the service life of the cutter. At the same time, it is easy to affect the cutting effect of the cutter during the cutting process.

Embodiment 1

[0026] A cutting knife preparation process of a high-speed circular cutter, comprising the steps of: designing a cutting knife preparation process of a high-speed circular cutter, comprising the steps of: comprising the steps of:

[0027] S1. Select raw materials, 2 parts of carbon, 1 part of tungsten, 0.6 parts of zinc, 0.3 parts of copper, 5 parts of chromium, 0.2 parts of magnesium, 3 parts of manganese, 2 parts of nickel, and 60 parts of iron. By adding carbon, tungsten and chromium, It enhances the strength and wear resistance of the cutter, prevents the blade from being worn and rolled, and the addition of manganese material has the functions of deoxidation, desulfurization and regulation, prevents the formation of carbides on the grain edge of the cutter, and also increases the cutting edge. Strength, toughness, hardenability;

[0028] S2, crushing the raw materials, and mixing the crushed raw materials;

[0029] S3. Put the mixed raw materials into the vacuum reaction...
