Preparation method of porous circular knife with milling and grinding functions

The invention discloses a preparation method of a porous circular knife with milling and grinding functions. The preparation method comprises the following three steps: S1, designing the structure and the size of the circular knife; s2, manufacturing a primary product of the circular knife; and S3, the final finished porous circular knife is manufactured. The 3D additive printing technology is utilized, the circular knife can be rapidly manufactured without a mold, the precision and the production efficiency of the circular knife are effectively improved, the manufacturing cost of the circular knife is reduced, the service life of the circular knife is effectively prolonged by mixing the chopped lignocellulose particles and the alloy microparticles, and the production cost of the circular knife is reduced. And the short cut lignocellulose particles are burnt out and automatically disappear by utilizing high temperature, so that irregular pores are left on the surface of the circular knife, the anti-burning ef
