Abstract

Hard turning is used more and more frequently for finishing of precision hardened bores, namely for replacement of grinding. This paper studies the experimental results performed for qualifying of surfaces machined with hard boring. It presents the results of surface roughness measurements (2D, 3D) and indicates the changes occurring in the surface layer. It proves that the presented surface quality characteristics of the investigated parts suit the requirements moreover in some cases they are even better than characteristics of surfaces machined by grinding. As a summary it is stated if the cutting parameters are chosen well, surfaces and/or parts with better wear resistance and higher durability can be manufactured.
