The application of coolants and lubricants (CL) considerably contributed to the increase of the efficiency of material removal in metal machining procedures. Both the cooling and the lubricating effect reduces the load on the tools, thus facilitates the partition of the material and the formation of a better surface quality. This article seeks to ascertain whether given production task – namely the machining of a hard surface – can be fulfilled with the same accuracy and economic efficiency if using less CL.
