Possibility of Reducing Environmental Load in Hard Machining

The development of metal machining processes and procedures has been characterized by aiming at accuracy and economy for decades. The applied coolants and lubricants helped this process; however, they are polluting the environment. For today that is a social demand and technical possibility that environmental aspects should predominate better in production engineering. In the frame of this article, through the application of dry hard turning we shall spotlight on its economy and efficiency. We shall prove that, keeping the same accuracy and economic efficiency, it is possible to choose a machining process by which the environmental load can be reduced compared to the most frequently applied grinding.
