Objective. Roughness of the flank surface of linter saw teeth when abrasive blasting with black carbide particles. Methods. The method of full-factor mathematical planning of the experiment is applied. Results. The regression equations are obtained, which make it possible to assess the degree of influence of the processing parameters on the height parameter of the surface roughness. As a result of abrasive blasting of linter saw teeth, a favorable micro-profile of their side surfaces was formed. Such a surface profile is able to enhance the contact interaction with the cotton fiber and to carry out its additional scraping from the seeds. Conclusion. An intensification of the linting process has been achieved due to the activation of the lateral surfaces of the teeth of the roughly created surface with a certain step and height of the roughness.
