S. , Master’s Degree student, e-mail: manhunt.47@yandex.ru Tambov State Technical University, 106 Sovetskaya str., Tambov, 392000, Russian Federation Abstract Theoretical and experimental studies of wear resistance through lathe and template-controlled turning/boring of ring to increase its wearability are carried in this article. Experimental studies were conducted on a special machine by rings processing. The studies of bits wear resistance were conducted by measuring of bits wearability depending on tooling material grade. According to studies results, the application of throw-away carbide inserts with wear-resistance coating can increase bits wear resistance in comparison with current in more than by half. As the result of work, the studies of bits wear resistance were tested and proved under factory conditions.
