Abstract. Objective. The surface layer of the flank surfaces of the saw blade teeth after abrasive blasting. Methods. The simulation of the interaction of abrasive grains and the metal surface of parts depending on the ratio of the cut thickness and the radius of rounding of the top of the abrasive particle. Results. The condition of the contact interaction of the abrasive grain with the processed surface of the part is obtained when microcutting occurs - scratching with the formation of detached microchips. This process can be easily accomplished by abrasive blasting with a sandblaster. In the process of abrasive blasting of the flank surfaces of the teeth of linter saws, a favorable micro-profile is formed, characterized by the height and pitch of irregularities. These roughness parameters, commensurate with the cotton fiber diameter, increase the linting efficiency. Conclusion. Abrasive blasting of black teeth of linter saws with silicon carbide as a result of plastic deformation and microcutting creates a hardened layer and roughness parameters that contribute to the intensification of the linting process.
