Abstract

The study examines the effect of TiN coatings, deposited on inserts of cutting ceramics, on the cutting temperature in machining of alloyed case-hardened steels. The study has revealed a substantial decrease of temperature during cutting with coated tools of cutting ceramics as compared with temperature for uncoated tools of cutting ceramics. Positive transformation of the thermal state during the cutting process with the use of coated ceramic tools can improve the quality of machined surfaces. The study has revealed the reduction in thickness of "white layer" of surfaces of machined workpieces of hardened high-alloyed steels in use of coated ceramic tools and the increase of cutting properties of coated ceramic tools.
