Precise and reliable information on the machinability of a material before it enters the machining process is a necessity, and hypotheses must be tested through verification of actual methods. This article presents conclusions of machinability tests on a new austenitic stainless steels X2Cr12Ni12MoTiN and describes appropriate parameters for the cutting zone during the process of turning. The content of this article also focuses on the analysis of selected basic indicators of steel machinability: quality of the processed surface. The results of the article are conclusions for working theory and practice for turning of austenitic stainless steels. Based on the cutting tests, cutting speeds of 80 to 200 m/min, feed rate of 0.05 to 0.2 mm and solid carbide insert WNMG 080404-NF.
