The progress and working principle of microblasting surface treatment technology were introduced, and the effect of microblasting on the surface integrity and cutting performance of coated tools was analyzed. It is found that the microblasting can improve the surface roughness of the coated tool and the residual compressive stress on the surface of the coating, so the tool cutting performance is improved and its service life is prolonged. The effects of the microblasting surface treatment technology on the surface of coated tools were summarized, and the microblasting surface treatment technology was summarized. The results provide reference for surface treatment and green intelligent manufacturing of coated cutting tools.
