Keywords Hard turning, hard machining, polycrystalline boron nitride, development of cutting tools, economical aspects and benefits of hard turning, grinding 1. It shows the confrontation between grinding and alternative technologies in production, machines and parts of machines, for its hard turning.

The work presents the characteristics of hard turning process, its development of trends and economical aspects. Both the development of processing technologies, and above all, the new cutting tools of construction materials such as regular polycrystalline boron nitride (PCBN) and the development of the construction machine tools enable to reduce significantly costs of production. PK Abstract New production technologies are designed to improve productivity, product quality, flexibility and environmental performance of production processes of machines. Grinding - economical aspects M.Sc Engg Jakub Siwiec Supervisor: dr hab. Broušení - ekonomické aspekty Hard Turning vs.
