Increasing demands for reducing the surface roughness of components impose high requirements for finishing operations. As a result, it creates a space for the application of new progressive methods for the surface finishing of components. The experimental activity referred to in this paper aims at comparing the conventional method of surface finishing (surface grinding followed by polishing) and a progressive finishing operation – forming with a diamond tip. The experiment was designed for the Wotan RJN 44 grinder and the Wagner WDR 1000 lathe. As the material to be machined, was chosen X17CrNi16-2. Forming with a diamond tip was made using a tool from Baublies, DDW type. The aim of this experiment was to compare the two finishing operations with the criterion for evaluating surface roughness Ra = 0.2 µm.Keywords: diamond tool polishing, grinding, finishing holes
