Abstract

In this paper the experimental results of newly developed cutting inserts with special geometry and position for machining of hardened surfaces are summarized. The design of the tool holder and cutting insert allows the increase of the applied feed values in hard turning. Experiments are carried out at increased feed in bore turning procedure and the results are compared with the nowadays used conventional turning technology.
